The observation of high energy (E > 1 TeV) electrons in the cosmic radiation provides important information on the distribution and energetics of local cosmic-ray sources. 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. Their locally observed energy spectrum above 1 TeV is expected to reflect the distribution and abundance of nearby acceleration sites. However, the rates at these energies are low and the direct detection would require unfeasibly large balloons or satellite born detectors. CREST, a balloon-borne detector array of 1024 BaF2 crystals, overcomes this hurdle: it will measure the intensity and spectrum of multi-TeV electrons by detecting 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 about 50 TeV. Following an engineering flight in spring of 2009, CREST will be flown in a circumpolar orbit on an upcoming Antarctic long-duration balloon flight.
