AbstractGamma-ray astronomy is generally viewed as an adjunct to cosmic ray physics. As such, the observation of very high energy gamma-rays will allow a new and complementary means of examining the origin and evolution of cosmic rays. However, at present the atmospheric Cerenkov technique (the technique by which very high energy gamma-rays are observed) is seriously hampered by limited flux sensitivity. Monte Carlo simulations suggest that the application of imaging to the atmospheric Cerenkov technique will provide a much needed increase in sensitivity. The successful application of imaging to very high energy gamma-ray observations of the Crab nebula will be discussed, as will improved techniques for calibration and noise rejection. These observations permit an improved estimate of the nebular magnetic field strength.
