Abstract :
The results of NaI scintillator measurements of the energy spectrum of degraded proton beams at the Northeast Proton Therapy Center at Massachusetts General Hospital are described. Measurements are presented for both the typical radiation test beams presently in use and for a configuration that results in a smaller energy spread at low energies.
