[0002] High-purity germanium detectors, considered the gold standard in nuclear radiation detection, are widely used in nuclear power, environmental protection, homeland security, and cutting-edge basic scientific research. The high-purity germanium crystal used for electrode fabrication is the core component of the detector system, and its manufacturing principle is based on a PN junction. This means that both electrode fabrication and intrinsic region processing are involved. The intrinsic region processing technology is crucial to the long-term stability and lifespan of the detector. When processing the intrinsic region, the electrode areas of high-purity germanium detectors not only have planar surfaces but also curved surfaces and other irregular structures, making mask etching difficult for users, resulting in poor etching effects that fail to meet user requirements.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 2 The present invention provides the following technical solution:

[0020] A high-purity germanium detector electrode mask fixture includes a base 1, a mounting sleeve 2, and a sealing module. The mounting sleeve 2 is mounted on the base 1, and the bottom of the mounting sleeve is a connecting plate 21. The connecting plate 21 at the bottom of the mounting sleeve 2 is connected to the base 1 by fastening bolts. A high-purity germanium crystal is installed inside the mounting sleeve 2. The sealing module is installed on the top of the mounting sleeve 2. The sealing module is used to seal the top part of the high-purity germanium crystal that does not need to be etched. The sealing module includes a sealing ring 4, a sealing gasket 5, a mounting bracket 6, and a top-pressure screw 8. The sealing ring 4 is installed at the bottom of the top-pressure sleeve 25, which is fixedly set on the top of the mounting sleeve 2 and located inside the mounting sleeve 2. During the process of fixing the base 1 and the mounting sleeve 2 with fastening bolts, the base 1 can push the part inside the mounting sleeve 2. The high-purity germanium crystal sealing ring 4 is pushed and squeezed to prevent the etching solution from entering the gap between the high-purity germanium crystal sidewall and the mounting sleeve 2, thus avoiding etching damage to the high-purity germanium crystal. The mounting bracket 6 is fixedly installed on the top of the mounting sleeve 2 by fixing bolts. The pressing screw 8 is screwed into the mounting bracket 6 by threads. A sealing gasket 5 is provided at the bottom of the pressing screw 8. The top of the mounting sleeve 2 is an opening 26. The pressing screw 8 is inserted into the mounting sleeve 2 through the opening 26. During the screwing process, the pressing screw 8 moves continuously toward the high-purity germanium crystal until the sealing gasket 5 is pressed against the top of the high-purity germanium crystal. Both the sealing gasket 5 and the sealing ring 4 are pressed and adhered to the top wall of the high-purity germanium crystal in the mounting sleeve 2, sealing and protecting the part of the high-purity germanium crystal that does not need to be etched.

[0021] A knob 7 is provided at the end of the top pressure screw 8 away from the sealing gasket 5, which makes it easy for the user to rotate the top pressure screw 8.

[0022] The mounting bracket 6 has a gantry-shaped structure. The mounting bracket 6 is bolted to the support plate 24 set at the top of the mounting sleeve 2, which facilitates the installation of the sealing module.

[0023] The base 1 is provided with a boss 11, which is adapted to the mounting sleeve 2. The boss 11 is inserted into the mounting sleeve 2 and is used to push the high-purity germanium fastener toward the sealing ring 4.

[0024] A sealing ring 3 is provided between the base 1 and the connecting plate 21. The sealing ring 3 can seal the gap between the connecting plate 21 and the base 1 to prevent the etching solution from entering the mounting sleeve 2 and causing excessive etching of the high-purity germanium crystal.

[0025] The sealing ring 3 is located between the first mounting slot 13 at the base 1 and the second mounting slot 23 at the connecting plate 21.

[0026] The top of the base 1 is provided with an annular limiting protrusion 12, which is adapted to the limiting slot 22 at the bottom of the connecting plate 21. The limiting protrusion 12 is inserted into the limiting slot 22 to limit the matching between the connecting plate 21 and the base 1.

[0027] The sealing gasket 5 and the sealing ring 4 are made of elastic sealing material. They have a certain degree of elasticity and can be squeezed while having good sealing performance, ensuring the etching effect of high-purity germanium crystal.

[0028] The specific implementation process is as follows:

[0029] When using this high-purity germanium detector electrode mask fixture to install the high-purity germanium crystal to be etched, first, install the high-purity germanium crystal in the mounting sleeve 2, then install the base 1 into the mounting sleeve 2, so that the protrusion 11 of the base 1 is inserted into the mounting sleeve 2, the limiting protrusion 12 of the base 1 is inserted into the limiting groove 22 of the connecting plate 21, and the sealing ring 3 is inserted into the first mounting groove 13 and the second mounting groove 23. During the process of fixing the base 1 and the connecting plate 21 with fastening bolts, the protrusion 11 of the base 1 is fed towards the mounting sleeve 2, pushing the high-purity germanium crystal towards the sealing ring 4, so that the sealing ring 4 is tightly attached to the high-purity germanium crystal, and the sealing ring 3 is also clamped and squeezed by the base 1 and the connecting plate 21, so that the sealing ring 3 seals the gap between the base 1 and the mounting sleeve 2; then, turn the knob 7, the knob 7 drives the top pressure screw 8 to rotate at the mounting bracket 6 and feed towards the mounting sleeve 2, so that the sealing gasket 5 at the end of the top pressure screw 8 is attached to the high-purity germanium crystal.

[0030] This high-purity germanium detector electrode mask fixture places a high-purity germanium crystal in the mounting sleeve 2. During the installation and fixing process of the mounting sleeve 2 and the base 1, the base 1 pushes the high-purity germanium crystal, so that the top of the high-purity germanium crystal is tightly fitted with the sealing ring 4. Then, the sealing gasket 5 is passed through the opening 26 at the top of the mounting sleeve 2 by the screw and pressed against the top of the high-purity germanium crystal. Through the action of the sealing ring 4 and the sealing gasket 5, the top part of the high-purity germanium is sealed. Then, the fixture is placed in the etching solution to etch the high-purity germanium crystal. This device can be adapted to etch various high-purity germanium crystals with curved tops, enhancing the etching effect of high-purity germanium crystals.
