A scanning target profile monitor for the slow extracted beam at the AGS

PDF Version Also Available for Download.

Description

The purpose of this new instrument is for probing beam halo and obtaining beam profiles of the resonant extracted beam at the AGS. The device described here is a prototype version, to obtain data and prepare for a more permanent device. The goals of the permanent device are to allow emittances of low current, but high intensity slowly extracted beams to be accurately measured and to have a diagnostic for probing the wings of the beam distribution. The device works on secondary emission from thin targets as well as scattering into two scintillator telescopes. The targets are movable over the ... continued below

Description

The device described here is a prototype version, to obtain data and prepare for a more permanent device. The goals of the permanent device are to allow emittances of low current, but high intensity slowly extracted beams to be accurately measured and to have a diagnostic for probing the wings of the beam distribution. The device works on secondary emission from thin targets as well as scattering into two scintillator telescopes. The targets are movable over the entire aperture at the device. The performance of this new device has exceeded expectations. The authors were very concerned about singles rates in the area, since the telescopes were located inside the beam enclosure and had effectively no shielding. The singles rates were not insignificant, as high as 1 MHz, but the triple coincidence circuitry had no problems contending with these rates.
