Abstract

A superconducting X-ray detection apparatus has a refrigerator, a cooling head cooled by the refrigerator, and a stacked structure connected to an end portion of the cooling head. The stacked structure comprises a sensor holder, a low-temperature first-stage amplifier connected to the sensor holder, and a superconducting X-ray detector mounted on the low-temperature first-stage amplifier.

Claims (14)

1. A superconducting X-ray detection apparatus comprising: a refrigerator; a cooling head cooled by the refrigerator and a stacked structure connected to an end portion of the cooling head, the stacked structure comprising a sensor holder, a low-temperature first-stage amplifier connected to the sensor holder, and a superconducting X-ray detector mounted on the low-temperature first-stage amplifier.

2. A superconducting X-ray detection apparatus according to claim 1 ; further comprising a superconductive member disposed between the sensor holder and the low-temperature first-stage amplifier.

3. A superconducting X-ray detection apparatus according to claim 1 ; further comprising a superconductive member disposed between the superconducting X-ray detector and the low-temperature first-stage amplifier.

4. A superconducting X-ray detection apparatus according to claim 2 ; wherein the superconductive member comprises a superconductive foil.

5. A superconducting X-ray apparatus according to claim 3 ; wherein the superconductive member comprises a superconductive foil.

6. A superconducting X-ray analyzer comprising: an electron microscopy system having an electron beam source for irradiating a sample with an electron beam; and a superconducting X-ray detection apparatus according to claim 1 for detecting X-rays generated from the sample irradiated with the electron beam.

7. A superconducting X-ray analyzer according to claim 6 ; further comprising a superconductive member disposed between the sensor holder and the low-temperature first-stage amplifier of the detection apparatus.

8. A superconductor X-ray analyzer according to claim 6 ; further comprising a superconductive member disposed between the superconducting X-ray detector and the low-temperature first-stage amplifier.

9. A superconducting X-ray analyzer according to claim 7 ; wherein the superconductive member comprises a superconductive foil.

10. A superconducting X-ray analyzer according to claim 8 ; wherein the superconductive member comprises a superconductive foil.

11. A superconducting X-ray detection apparatus comprising: a cooling head; and a stacked structure connected to an end portion of the cooling head, the stacked structure comprising a superconducting X-ray detector, a low-temperature first-stage amplifier, and a superconductive member disposed between the superconducting X-ray detector and the low-temperature first-stage amplifier.

12. A superconducting X-ray detection apparatus according to claim 11 ; wherein the superconductive member comprises a superconductive foil.

13. A superconducting X-ray detection apparatus according to claim 11 ; further comprising a sensor holder disposed between the cooling head and the low-temperature first-stage amplifier.

14. A superconducting X-ray analyzer comprising: an electron microscopy system having an electron beam source for irradiating a sample with an electron beam; and a superconducting X-ray detection apparatus according to claim 11 for detecting X-rays generated from the sample irradiated with the electron beam.
