Descrição

We report on the optical readout of the gas electron multiplier (GEM) operated with a gaseous mixture suitable for the detection of thermal neutrons: 3He-CF4. A CCD system operating in the 400-1000 nm band was used to collect the light. Spectroscopic data on the visible and NIR scintillation of He-CF4 are presented. Images of the tracks of the proton and triton recorded with a triple GEM detector are also shown. http://www.sciencedirect.com/science/article/B6TJM-45HFC9M-2D/1/c77549a88a84ef08c2d169c0b4e97ed8
