Abstract :
Compact 14-MeV proton and 7-MeV deuteron linacs for use in positron emission tomography (PET) have been studied, and conceptual designs for low-energy beam transport (LEBT), radio-frequency quadrupole (RFQ), and drift tube linacs (DTL) have been achieved. The machines are compact and simple enough to be operated in hospitals. The LEBTs consist of two Einzel lenses and are about 25-cm long. The 425-MHz proton RFQ is designed for 50-mA peak current, and the 425-MHz deuteron RFQ is designed for 25-mA peak current. Both 850-MHz DTLs use permanent quadrupole magnets and have a high acceleration field of 15 MV/m with a peak field of twice the Kilpatrick limit
