Measurements from a Compact Cost‐Effective Beamline for the THC14 PET Cyclotron;

The THC14 PET Cyclotron produced by THALES specifies two compact cost-effective beamlines for high current PET radioisotope production. The design and development of the beamline system was reported previously in NIM B 261 (2007) pp 809-812. This paper describes the successful testing of this compact beamline at the first installation. A series of measurement data are presented starting from low current scintillator image data, higher current beam diagnostic data (baffles, collimators, targets) and finally a simultaneous dual beam run on Faraday Cups. The beamline system has proven to be a flexible and valuable tool for optimizing high current beam intensity distribution on target in a well-instrumented manner. This ability to tailor the beam characteristics for the target is particularly important as high power targets are developed which can handle very high beam currents.
