“…The purpose of this prototype instrument [1] is for probing beam halo and obtaining beam profiles of the resonant extracted beam at the AGS. The goals of the possible subsequent next generation permanent device are to allow emittances of low current, but high intensity slowly extracted beams (SEB) to be accurately measured, and to have a diagnostic for probing the wings of the beam distribution.…”

An instrument for probing beam halo and obtaining beam profiles is discussed. 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 slow extracted beam emittances to be more routinely 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. Data will be presented, as well as a description of the design of the system.

“…The implementation of this optics under the highest intensity operation was the priority activity at the '97 startup and into the run. Instrumentation upgrades to further refine the emittance measurement and to allow quantitative measurements of the tails of the extracted beam were implemented (flags, and scanning targets) [4].…”

The AGS accelerator complex is into its third year of 60+ ~1 0 '~ (teraproton = Tp) per cycle operation. The hardware making up the complex as configured in 1997 is briefly mentioned. The present level of accelerator performance is discussed. This includes beam transfer efficiencies at each step in the acceleration process, i.e. losses; which are a serious issue at this intensity leveI. Progress made in understanding beam behavior at the Linac-to-Booster (LtB) injection, at the Booster-to-AGS (BtA) transfer as well as across the 450 ms AGS accumulation porch is presented. The state of transition crossing, with the gamma-tr jump is described Coherent effects including those driven by space charge are important at all of these steps.
