Indiana University Cyclotron Facility - The First Year of Operation

A progress report on the Indiana University Cyclotron Facility in its first year of operation is presented. Research productivity in the period was substantial, with approximately 225 shifts of beam delivered to some 30 experiments. Nearly half the use was by user groups from outside Indiana University. The versatility of the I.U.C.F. accelerator system was evident from the delivery of 20 proton energies in the range 35 to 164 MeV, 6 energies of 6Li between 55 and 100 MeV, and also deuteron, alpha and 7Li beams. Beam quality was good and scattering spectra with overall energy resolution of 0.05% fwhm at 135 MeV were obtained. Intensities on target began at a few nano-amperes and had risen to some hundreds of nanoamperes by the end of the year. Reliability was satisfactory with unscheduled downtime beginning at about 30% of scheduled operation and falling to below 20% by year end.
