Description
VERITAS is an array of four imaging atmospheric Cherenkov telescopes in southern Arizona and is one of the world's most sensitive detectors of very high energy (VHE: >100 GeV) gamma rays and cosmic rays. While the primary focus of VERITAS is to detect and understand gamma-ray sources, techniques can be developed to distinguish and measure individual cosmic-ray species in the data. In this talk we'll survey the status of VERITAS measurements of cosmic rays--including progress towards an all-electron spectrum, prospects for the measurement of the positron fraction, and work towards distinguishing high-Z particle species with a direct Cherenkov technique. We'll also discuss recent VERITAS gamma-ray results that are directly relevant to the propagation of cosmic rays.
