Abstract :
The need to accelerate low-energy partially stripped heavy ions requires the pick-up electrodes (PUEs) to operate in a 3*10/sup -11/ torr vacuum. The PUEs are to measure the beam position to an absolute accuracy of +or-0.5 mm and must therefore be mechanically stable despite the requirement that they be vacuum fired at 950 degrees C and baked periodically to 300 degrees C. The mechanical design of the PUEs is described, and the automated test procedure used to ensure the stability, accuracy, and linearity of each unit is discussed.<>
