Participation in the development of a very sensitive camera for a new generation 17 m diameter cerenkov telescope

Objective



Research objectives and content The researeh object is the the development of a high sensitivity camera for the MAGIC project, a 17 m diameter imaging air Cherenkov telescope. A new generation of air Cherenkov will be required to bridge the gap in our knowledge of the atrophysical spectrum between satellite gamma-ray measurements (up to 30 GeV) and the 300 GeV gamma-ray energy theshold of their predecessors (e.g. the 10 m Whipple Telescope). A lowering of the threshold will be achieved through larger Cherenkov light collecting mirrors and the replacement of photomultiplier (PMT) based cameras by high quantum efficiency (QE), solid state photo-sensors. The standard eamera will be based on intensified photocells with GaAsP photoeathodes read out by an avalanehe diode, giving a gain up to 24 000. With this type of eamera it is estimated to gain a factor of 3 to 4 in signal eompared to a eLasieal PMT camera Training content (objective, benefit and expected impact) The main objective will be to develop and build the eamera. Besides learning a lot about the physies of this eamera there will be lots of ways to teaeh myself in partiele physies and astrophysics. The knowledge I can gain in this project will open many possibilities for the future. Links with industry / industrial relevanee (22) This projeet is being carried out in eollaboration with firms such as Hamamatsu, whis is one the leading firms in the world.
