Abstract

A new thin window support system for the accelerator production of positron emitters (e.g. ¹⁷F, ¹⁸F ¹¹C, ¹⁵O) has been developed. The integrated support grid and cooling design has been optimized for 6–13 MeV protons or deuterons. The water-cooled support grid regularly operated at >100 μA of 6 MeV deuterons and protons. The grid performed without failure at ⩾50 μA of 13 MeV protons on a 3.1 MPa gas target using 25.4 μm aluminum target foil. Transmission for the smallest hole grid of 72% based on uniform parallel beam agreed with the measured yield of 71±1% compared to the theoretical maximum yield.
