| Abstract |
The ANU Heavy Ion Facility comprises a 15 MV electrostatic accelerator followed by a superconducting linac booster. The beam is foil stripped in the terminal and then stripped again to provide high charge states at the entrance to the linac. Employment of double terminal stripping allows the system to accelerate beams with mass up to 70 amu. The disadvantage of double terminal stripping is low beam intensity of few particle nA delivered to the linac. The linac encompasses twelve β=0.1 lead tin plated Split Loop Resonators (SLR) housed in four module cryostats. One of the linac set up procedures that developed at ANU utilises U-bend at the end of the linac. One special wide Beam Profile Monitor (BPM) is installed after 90 degrees magnet. The technique allows to set correct phase by observing the displacement of beam profile versus phase shift of the last phase locked resonator. In this paper a simple method has been proposed to improve sensitivity of commercially available BPM for efficient operation with low beam intensities. The system demonstrated very high stability, simplicity of operation and high reliability allowing sustained operation of the LINAC facility.
