The present invention relates to a doubly bent X-ray focusing device, a doubly bent X-ray spectroscopic device, apparatuses provided with the devices, and methods for manufacturing the devices.
Conventionally, a curved X-ray spectroscopic device has been known which has a concave shape in one direction or two directions, and is configured to focus and/or monochromate X-rays. In particular, in order to efficiently monochromate and focus X-rays, it is necessary to use a doubly curved X-ray spectroscopic device having a large spectroscopic surface that is concave in two directions. In this regard, deposition of a spectroscopic multilayer film on a substrate that has been machined into a predetermined doubly curved shape in advance is commonly performed. However, the substrate needs to have a surface roughness of several angstroms (several nm×10−1) in root-mean-square roughness, and polishing of such a doubly-curved-shaped substrate requires advanced technology and much labor, which results in significant increase in cost, and limited application. Meanwhile, an X-ray spectroscopic device (Patent Documents 1 and 2) has been known in which a silicon single crystal plate member is anode-bonded to a substrate having a predetermined curved shape. In this case, however, the plate member needs to be elastically deformed, and therefore, the degree of freedom of the bent shape of the plate member after being deformed is low. Under such circumstances, there has been proposed a crystal lens (Patent Document 3) which is manufactured by increasing the temperature of a crystal plate of Si, Ge, or the like to a temperature near its melting point, and applying a load to the crystal plate by using predetermined concave and convex dies to thermoplastically deform the crystal plate.

However, in the crystal lens manufacturing method disclosed in Patent Document 3, special equipment is required for performing the pressurizing deformation at high temperature. Further, not only the macro-shape of the forming die but also the micro-shape of the forming die (the surface roughness of the forming die) that adversely affects X-ray reflection characteristics are transferred onto the formed product. Therefore, even when an X-ray reflection coating or a synthetic multilayer is formed on the formed product, desired performance cannot be obtained.

Hereinafter, a doubly bent X-ray focusing device 1 according to a first embodiment of the present invention will be described. The doubly bent X-ray focusing device 1 of the first embodiment shown in
When the heating temperature to deform the glass plate 3 is less than 400° C., the glass plate 3 may sometimes not be formed to have a desired doubly bent surface even if the time for the heating and deformation is increased. On the other hand, when the heating temperature exceeds 600° C., although the time required for the heating and deformation is reduced, there is a risk that the surface roughness of the convex surface of the convex forming die may be transferred to the concave surface 3a of the glass plate 3. Therefore, the heating temperature to deform the glass plate 3 is preferably 400° C. to 600° C., and more preferably 450° C. to 550° C.
The blank glass plate 3, which has not been deformed, has a surface roughness not more than 0.5 nm in root-mean-square roughness. The blank glass plate 3 is, for example, a cover glass for microscopic observation or for a display of electronic equipment, and specifically is a rectangle plate made of borosilicate glass and having a long side of 75 mm, a short side of 25 mm, and a thickness of 0.15 mm. The thickness of the blank glass plate 3 is preferably not more than 1 mm because the thinner the blank glass plate 3 is, the more rapidly the blank glass plate 3 is heated and deformed, which facilitates forming. The dimension, shape, and material of the blank glass plate 3 may be other than those mentioned above as long as the surface roughness thereof is not more than 0.5 nm in root-mean-square roughness.
According to the doubly bent X-ray focusing device 1 of the first embodiment, the blank glass plate 3 is sandwiched between the doubly curved convex surface and the doubly curved concave surface that matches the doubly curved convex surface and is heated to a temperature of 400° C. to 600° C. to be deformed into the shape having the doubly bent surface. As a result, the glass plate 3 is not adversely affected by the surface roughness of the doubly curved convex surface 21a of the convex forming die 21 (
Next, a doubly bent X-ray focusing device assembly according to a second embodiment of the present invention will be described. A doubly bent X-ray focusing device assembly 6 of the second embodiment shown in
Since the doubly bent X-ray focusing device 1 has the self-supporting shape, it is sufficient that the base 7 is a fixture member to which the doubly bent X-ray focusing device 1 can be fixed, and the surface roughness of the concave surface 7a of the base 7 may be inferior to the surface roughness of the glass plate 3. The base 7 is not limited to the concave base 7 as shown in
Since the doubly bent X-ray focusing device assembly 6 of the second embodiment includes the doubly bent X-ray focusing device 1 of the first embodiment, the same effect as that of the doubly bent X-ray focusing device 1 of the first embodiment can be achieved.

Although the X-ray analyzing apparatus according to the fifth embodiment has been described as the X-ray fluorescence spectrometer provided with the doubly bent X-ray spectroscopic device assembly 16 of the fourth embodiment, the X-ray analyzing apparatus may be provided with at least one of: the doubly bent X-ray focusing device 1 of the first embodiment; the doubly bent X-ray focusing device assembly 6 of the second embodiment; the doubly bent X-ray spectroscopic device 11 of the third embodiment; and the doubly bent X-ray spectroscopic device assembly 16 of the fourth embodiment, or may be an X-ray analyzing apparatus other than X-ray fluorescence spectrometers.
Since the X-ray analyzing apparatus of the fifth embodiment is provided with at least one of: the doubly bent X-ray focusing device 1 of the first embodiment; the doubly bent X-ray focusing device assembly 6 of the second embodiment; the doubly bent X-ray spectroscopic device 11 of the third embodiment; and the doubly bent X-ray spectroscopic device assembly 16 of the fourth embodiment, the X-ray analyzing apparatus can perform highly accurate measurement while ensuring satisfactory focusing performance and/or spectroscopic performance.
Next, a method for manufacturing the doubly bent X-ray focusing device 1 according to a sixth embodiment of the present invention will be described. As shown in
In step S1, the glass plate 3 having the surface roughness not more than 0.5 nm in root-mean-square roughness is prepared. The blank glass plate 3 is, for example, a cover glass for microscopic observation or for a display of electronic equipment, and specifically, is a rectangle plate made of borosilicate glass and having a long side of 75 mm, a short side of 25 mm, and a thickness of 0.15 mm. The thickness of the blank glass plate 3 is preferably not more than 1 mm because the thinner the blank glass plate 3 is, the more rapidly the blank glass plate 3 is heated and deformed, which facilitates forming. The dimension, shape, and material of the blank glass plate 3 may be other than those mentioned above as long as the surface roughness thereof is not more than 0.5 nm in root-mean-square roughness.
In step S2, the convex forming die 21 having the desired doubly curved convex surface 21a is prepared. The doubly curved convex surface 21a of the convex forming die 21 is a toroidal surface in the manufacturing method of the present embodiment. The convex forming die 21 is made of stainless steel, and has a mass of 300 g. The doubly curved convex surface 21a has, in a plan view, a rectangular shape with a long side of 75 mm and a short side of 25 mm.
In step S3, the concave forming die 22 having the doubly curved concave surface 22a that matches the doubly curved convex surface 21a is prepared. The doubly curved concave surface 22a is a toroidal surface in the manufacturing method of the present embodiment. The concave forming die 22 is made of stainless steel. The doubly curved concave surface 22a of the concave forming die 22 has, in a plan view, a rectangular shape with a long side of 75 mm and a short side of 25 mm. The doubly curved concave surface 22a that matches the doubly curved convex surface 21a means the doubly curved concave surface 22a which is shifted from the doubly curved convex surface 21a by the thickness of the glass plate 3. The convex forming die 21 and the concave forming die 22 are machined dies, and the doubly curved convex surface 21a and the doubly curved concave surface 22a thereof are not subjected to special surface polishing. Therefore, these dies 21 and 22 are inferior in surface roughness to the blank glass plate 3.
In step S4, as shown in
In step S5A of
According to the manufacturing method of the sixth embodiment, the glass plate 3 is sandwiched between the doubly curved convex surface 21a and the doubly curved concave surface 22a that matches the doubly curved convex surface 21a, and heated to a temperature of 400° C. to 600° C. to be deformed into a shape having the doubly bent surface. As a result, even when the glass plate 3 is heated and deformed between the convex forming die 21 and the concave forming die 22, the glass plate 3 is not adversely affected by the surface roughness of the doubly curved convex surface 21a of the convex forming die 21, and has the surface roughness equivalent to that of the glass plate 3 before being heated and deformed. The reflection coating 5 is formed on the concave surface 3a of the glass plate 3. Therefore, it is possible to easily and inexpensively manufacture the doubly bent X-ray focusing device 1 having excellent focusing performance.
Next, a method for manufacturing the doubly bent X-ray focusing device assembly 6 according to a seventh embodiment of the present invention will be described. As shown in
In step S6A, the doubly bent X-ray focusing device 1 manufactured by the manufacturing method of the sixth embodiment is prepared.
In step S7A, the base 7 to which the doubly bent X-ray focusing device 1 is to be fixed is prepared. The same base 7 as that of the doubly bent X-ray focusing device assembly 6 of the second embodiment, for example, a concave stainless-steel base 7 having the same doubly curved concave surface 7a as the doubly curved concave surface 22a of the concave forming die 22, is prepared.
In step S8A, first, an adhesive, for example, epoxy resin, is applied to the entire concave surface 7a of the base 7 (
According to the manufacturing method of the seventh embodiment, since the doubly bent X-ray focusing device 1 manufactured by the manufacturing method of the sixth embodiment is fixed to the base 7, it is possible to easily and inexpensively manufacture the doubly bent X-ray focusing device assembly 6 having excellent focusing performance.
Next, a method for manufacturing a doubly bent X-ray focusing device assembly 6 according to an eighth embodiment of the present invention will be described. As shown in

In step S5C, the base 7 to which the deformed glass plate 3 is to be fixed is prepared. The same base 7 as that used in the manufacturing method of the seventh embodiment, for example, a concave stainless-steel base 7 having the same doubly curved concave surface 7a as the doubly curved concave surface 22a of the concave forming die 22, is prepared.
In step S6C, first, the convex forming die 21 and the deformed glass plate 3 are heated to a melting point of paraffin which is described later, and paraffin is applied to the convex surface 21a of the convex forming die 21, and then the concave surface 3a of the deformed glass plate 3 is superposed on the convex surface 21a having the paraffin. Then, the convex forming die 21 and the glass plate 3 are slowly cooled, whereby the glass plate 3 is held on the convex surface 21a of the convex forming die 21 due to the adhesion force of the paraffin. Next, an adhesive, for example, epoxy resin, is applied to the entire concave surface 7a of the base 7, and the convex surface 9 of the glass plate 3 adhered to and held by the convex surface 21a of the convex forming die 21 is superposed on and adhered to the concave surface 7a of the base 7, thereby fixing the glass plate 3 to the base 7.
After the deformed glass plate 3 is fixed, the entire structure, in which the convex forming die 21, the glass plate 3, and the base 7 are in the superposed state, is heated to the melting point of paraffin, whereby the convex forming die 21 is separated from the glass plate 3, and the paraffin remaining on the concave surface 3a of the glass plate 3 is removed. The paraffin used in this embodiment is desired to have a melting point at a low temperature that does not cause degradation of the adhesive, for example, 50° C. to 60° C.
In step S7C, the reflection coating 5 of Au (gold) that reflects X-rays is formed by, for example, vacuum deposition, on the concave surface 3a of the deformed glass plate 3 fixed to the base 7. Through the above-described process steps, the doubly bent X-ray focusing device assembly 6 is manufactured.
According to the manufacturing method of the eighth embodiment, as in the manufacturing method of the sixth embodiment, the glass plate 3 is sandwiched between the doubly curved convex surface 21a and the doubly curved concave surface 22a that matches the doubly curved convex surface 21a, and heated to a temperature of 400° C. to 600° C. to be deformed into a shape having the doubly bent surface. As a result, the glass plate 3 is not adversely affected by the surface roughness of the doubly curved convex surface 21a of the convex forming die 21, and has the surface roughness equivalent to that of the glass plate 3 before being heated and deformed. Then, the reflection coating 5 is formed on the concave surface 3a of the glass plate 3. Therefore, it is possible to easily and inexpensively manufacture the doubly bent X-ray focusing device assembly 6 having excellent focusing performance.
