Description
The bulk of the cosmic ray protons up to around 3 x 10^15 eV come from our Galaxy, with supernova shocks being the prime candidates for the acceleration sites. However, there is no evidence for the acceleration of particles in SNRs to the required energy from gamma-ray observations. It may be that the most energetic particles are accelerated in the early stages of Type II supernovae, resulting in prompt gamma-ray emission. I will review attempts to detect prompt gamma-rays from supernovae and consider the prospects for the Cherenkov Telescope Array (CTA).
