Keywords: | CsI photocathode; Noble gas scintillation | Issue Date: | 2007 | Citation: | Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment. 580:1 (2007) 214-217 | Abstract: | The performance of a new VUV photosensor, based on an micro-hole and strip plate (MHSP) electron multiplier with a CsI photocathode deposited on its top electrode, is described. This photosensor presents gains above 104 when operating in an Ar-5%Xe gas mixture at 1 atm. Although the gain of a single MHSP is not sufficient for efficient detection of single photons, this simple UV photosensor may be useful for the detection of higher light levels, such as primary- and secondary scintillation in noble gases. | URI: | https://hdl.handle.net/10316/4355 | DOI: | 10.1016/j.nima.2007.05.087 | Rights: | openAccess |
