An overview of the fast injection-extraction kicker systems of the Brookhaven AGS-booster complex

Abstract

The expansion of the Brookhaven accelerator facilities, and the ongoing efforts to raise the AGS beam intensity, have been a driving force for the addition of new kickers and the upgrading of older ones to meet this challenge. All kicker power supply systems are running above their design specifications to provide wider operating ranges. The newly upgraded Booster fast extraction kicker power supply was commissioned in September 1997. Its compact high voltage modulator structure offers a pulse length almost three times longer than the preceding package within the confines of the same physical space. The AGS A5 injection kicker and the AGS G10 extraction kickers are also discussed. In order to expedite design, assembly, and commissioning, and to facilitate interchangeability, standardized modules have been adopted where possible. This paper gives an overview of the AGS and Booster fast injection and extraction kicker systems including their parameters, structure and status.

Parameters for the injection, acceleration, and extraction of uranium ions in Booster, AGS, and RHIC

“…The rigidity that can be extracted from Booster into the BTA line is limited by the F3 extraction kicker. The advertised limit is Bρ = 9.5 Tm [12]. We have successfully extracted Au31+ ions (originating from Tandem) at Bρ = 9.43 Tm for several years.…”

FY2019 parameters for Gold ions in Booster, AGS, and RHIC

“…The magnetic rigidity of the ion in units of Tm is Bρ = kcp/Q (12) where k = 10 9 /299792458 and cp is given in units of GeV. The angular frequency is ω = 2πf.…”
