  An observation of the radio galaxy 3C295 during the calibration phase of the
Chandra X-ray Observatory reveals X-ray emission from the core of the galaxy,
from each of the two prominent radio hotspots, and from the previously known
cluster gas. We discuss the possible emission processes for the hotspots and
argue that a synchrotron self-Compton model is preferred for most or all of the
observed X-ray emission. SSC models with near equipartition fields thus explain
the X-ray emission from the hotspots in the two highest surface brightness FRII
radio galaxies, Cygnus A and 3C295. This lends weight to the assumption of
equipartition and suggests that relativistic protons do not dominate the
particle energy density.
