Abstract
Galactic cosmic-ray electrons are thought to be shock accelerated in supernova remnants as evident from observations of non-thermal X-rays and TeV gamma rays. Above ∼1 TeV the local electron spectrum is expected to reflect the distribution and abundance of nearby acceleration sites but rates are low and current and past electron detectors, typically flown by high altitude balloons, were limited by their short exposure times and small apertures. CREST, a balloon-borne detector array of 1024 BaF2 crystals will measure the intensity and spectrum of multi-TeV electrons by detecting the synchrotron photons emitted from electrons passing through the Earth's magnetic field. Thus CREST's acceptance is several times its geometric area providing sensitivity up to ∼ 50 TeV. CREST will be flown in a circumpolar orbit on an upcoming Antarctic LDB flight.
