“…We wanted to make reliable estimates of radiation heating effects on ISA magnets in ISA situations-injection, acceleration, beam cleanup, ejection.Ô ur philosophy was to design simple experiments which could (1) give an immediate result for the order of magnitude of the tolerance and (2) be easily interpreted by computer models of the heating process. By testing models at both 30 GeV (here) and at 400 GeV (at FNAL), we could determine the reliability of the nodels over the energy range important for ISABELLE.…”
