SiPM Based Focal Plane Detectors Operated Alongside PMTs for Large Imaging Atmospheric Cherenkov Telescopes

摘要

have been fabricated, along with their associated control electronics and specially designed light concentrators. A low-noise analog pulse summation circuit was used to implement rapid signal response (~2.5 nsec) for this detection area while maintaining resolution of individual photoelectron peak spectra used for calibration. Data recorded during camera operation is analyzed for comparison to the photomultiplier devices.
