A pinger system for the Los Alamos Proton Storage Ring

Developers at the Proton Storage Ring have long desired a modulator and electrode combination capable of kicking the 800 MeV proton beam enough to conduct tune measurements with full intensity beams. To provide tune data at any time throughout the accumulation cycle, a pinger system has been developed. In addition, to tune data the system described here can provide a series of kicks synchronized with the area between bunches. A 4 m electrode has been designed and constructed for this purpose. The design is flexible in that the electrode may be split in the center and rotated in order to provide vertical and horizontal electrodes each 2 m long. In addition, two solid-state pulse modulators that can provide 10 kV in burst mode at up to 700 kHz have been purchased. This hardware and its intended use are described.<<ETX>>
