Abstract: A large-area X-ray gas detector includes a housing having an inner cavity and a ray entrance communicated with the inner cavity, a thin entrance window and a signal collection module. The inner cavity is filled with a working gas which is a non-electronegativity gas sensitive to the X-ray. The entrance window is hermetically connected to the ray entrance such that the X-ray enters into the inner cavity. The signal collection module comprises an anode wire electrode layer and a cathode electrode layer arranged parallel with each other in the inner cavity, in which the anode wire electrode layer has an anode wire for accessing to a high voltage, and the cathode electrode layer is grounded. The anode wire electrode layer collects electrons generated by the working gas under an action of the X-ray.

Abstract: the present invention provides a method for forming a sensitive film for neutron detection, wherein the sensitive film is formed by electrophoresis coating, the liquid used for electrophoresis coating includes neutron sensitive material, electrophoresis paint and deionized water, and the neutron sensitive material is 10B single substance, 10B compound or mixture containing 10B. The sensitive film for neutron detection has the high detection efficiency because of the high content of 10B. The sensitive film for neutron detection has the uniform and stable film thickness, and excellent consistency. The production efficiency and the cost of the sensitive film are improved.
