Insert design PDF file and pictures describing the design with text.
Coating U-238 or Th-232 is essential for neutron detection in the range 2-14 MeV, but THGEM contains holes that should be protected from any coating material. So, a mask is designed to cover these holes.
The mask is made of stainless steel, 10 um laser tolerance with cut the plate to get the shape in the figure:
The lines in the mask has the following dimensions:
An adjustment holes will be cut in circle of 2.5 mm in diameter as shown:
To have the final shape for the mask.
Please look at the following file for more details for the manufacturer.
