摘要THGEMs based on a ceramic substrate have been successfully developed for neutron and single photon detection. The influences on thermal neutron scattering and internal radioactivity of both ceramic and FR-4 substrates were studied and compared. The ceramic THGEMs are homemade, of 200 mu m hole diameter, 600 mu m pitch, 200 mu m thickness, 80 mu m rim, and 50 mm x 50 mm sensitive area. FR-4 THGEMs with the same geometry were used as a reference. The gas gain, energy resolution and gain stability were measured in different gas mixtures using 5.9 keV X-rays. The maximum gain of a single layer ceramic THGEM reaches 6 x 10(4) and 1.5x 10(4) at Ne+CH4=95:5 and Ar + i-C4H10 = 97:3, respectively. The energy resolution is better than 24%. Good gain stability was obtained during a more than 100 hour continuous test in Ard+CO2=80:20. By using a Pu-239 source, the alpha deposited energy spectrum and gain curve of the ceramic THGEM were measured.
