PEBS — Positron electron balloon spectrometer
چکیده انگلیسی

The best measurement of the cosmic ray positron flux available today was performed by the HEAT balloon experiment more than 10 years ago. Given the limitations in weight and power consumption for balloon experiments, a novel approach was needed to design a detector which could increase the existing data by more than a factor of 100.Using silicon photomultipliers for the readout of a scintillating fiber tracker and of an imaging electromagnetic calorimeter, the PEBS detector features a large geometrical acceptance of 2500cm2sr for positrons, a total weight of 1500kg and a power consumption of 600W. The experiment is intended to measure cosmic ray particle spectra for a period of up to 20 days at an altitude of 40km circulating the North or South Pole.A full Geant4 simulation of the detector concept has been developed and key elements have been verified in a testbeam in October 2006 at CERN.
