Evaluation of Flat Microchannel Plate Photomultipliers for Use in a Portable Air Fluorescence Detector

Abstract:

Future applications of the air fluorescence technique will require robust, portable detectors, versatile enough to be deployed in remote areas with little infrastructure. One such experiment is the Gamma Ray and Neutron Decay Scan of the Galaxy (GRaNDScan), which proposes to survey the EeV sky by observation of γ and cosmic ray air showers in the southern hemisphere. To view a 30 field at or exceeding a resolution of 1, GRaNDScan will employ a lensless Schmidt optical system, with the light-sensitive element in each detector consisting of a spherical surface of tiled photomultipliers. Currently, the BURLE 85001 micro channel plate photomultiplier (MCP PMT), a low profile device appropriate for tiling, is the primary candidate for these cameras. In this paper, we discuss the preliminary design of the GRaNDScan optics, the basic characteristics of the 85001 photomultiplier, and the suitability of this device for use …
