   We propose to observe the distant (z=0.46) X-ray luminous cluster of
   galaxies surrounding the radio galaxy 3C295. A previous, short ASCA
   observation of the source suffered from severe technical problems and
   was insufficient to permit detailed study. The proposed 60 ks
   observation will permit the first detailed spectral analysis, enabling
   us to separate the multiphase emission associated with the cooling flow
   from the ambient cluster gas. When combined with the ROSAT HRI imaging
   data already gathered, the ASCA data will allow us to determine the
   mean temperature and metallicity of the cluster gas, the radial
   distributions of gas density, cooling rate, gas mass and total mass,
   and will provide a measure of the age of the cooling flow. This is of
   much interest for such a distant cluster.
