	The Isotope Production Facility (IPF) at LANSCE produces medical radionuclides strontium-82 and germanium-68 by bombarding rubidium chloride and gallium metal targets respectively with a 100 MeV proton beam, 230 uA average current. Rastering the proton beam is necessary to distribute beam power deposited as heat in the target and allow for higher average beam current for isotope production. We currently use a single circle raster pattern with constant amplitude and frequency. In this paper, we demonstrate two different varying amplitude raster patterns (concentric circle and spiral) to achieve uniform target coverage and expose more target volume to beam heating. In this proof-of-principle experiment, we compare beam spot uniformity measured by irradiating films and foils for both raster patterns.

The Isotope Production Facility (IPF) at LANSCE produces medical radionuclides strontium-82 and germanium-68 by bombarding rubidium chloride and gallium metal targets respectively with a 100 MeV proton beam, 230 uA average current. Rastering the proton beam is necessary to distribute beam power deposited as heat in the target and allow for higher average beam current for isotope production. We currently use a single circle raster pattern with constant amplitude and frequency. In this paper, we demonstrate two different varying amplitude raster patterns (concentric circle and spiral) to achieve uniform target coverage and expose more target volume to beam heating. In this proof-of-principle experiment, we compare beam spot uniformity measured by irradiating films and foils for both raster patterns.
