Embodiment Construction

[0040] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0041] The present invention proposes a method for preparing a support structure of a microstructured gas detector, the specific process of which is as follows figure 1 shown, including:

[0042] S0, flatten the hot melt adhesive film 1 attached to the release paper 2 .

[0043] In one embodiment of the present invention, the hot-melt adhesive film 1 used is adhered to the silicone release paper 2 and is in the shape of a roll. Therefore, before laser cutting, at first, the hot-melt adhesive film 1 is cut into small pieces as required and Flatten it by applying pressure, such as figure 2 shown. Secondly, use adhesive tape to fix the release paper 2 with the hot melt adhesive film 1 on the laser cutting platform. When...

Abstract

A microstructured gas detector support structure and a preparation method thereof, the method comprising: S1, setting laser cutting parameters, the parameters including cutting distance, size and graphics; The adhesive film (1) is laser-cut until the hot-melt adhesive film (1) is completely cut through but the release paper (2) is not cut to form an array of support gaskets (5) with a frame (6); S3, Adhere one side of the hot-melt adhesive film (1) of the support gasket (5) array with the frame (6) to the read-out anode plate (3) of the microstructure gas detector, and use a flat hot press to remove the pressure from the release paper ( 2) Applying pressure and hot pressing on one side to form a support structure; S4, placing the stainless steel wire mesh (7) of the microstructure gas detector on the support structure and hot pressing, so that the readout anode plate (3) and the stainless steel wire mesh (7) ) is actually connected. The method has high processing precision and efficiency, and the support structure prepared by the hot-melt adhesive film increases the stability of the detector.

Description

technical field [0001] The invention relates to the field of microstructure gas detectors, in particular to a support structure of a microstructure gas detector and a preparation method thereof. Background technique [0002] In the commonly used microstructure gas detector Micromegas, its amplifying structure is composed of a stainless steel wire mesh and a readout anode, and an air gap is formed between the two using a support structure. The size and uniformity of the air gap between the stainless steel wire mesh and the anode have a great The amplifier magnification has a direct impact. [0003] In the prior art, the method used is to combine the anode circuit board and two layers of photosensitive film (single layer thickness is 64um) by rolling together, and then use photoetching technology to make the photosensitive film Support pillars with a diameter of 300um and a spacing of 2mm. Then, a stainless steel wire mesh with a certain tension is placed on the surface of t...
