TI - Development of a Compact Linear ZAO NEG Pumping System J2 - Proc. of ECRIS2020, East Lansing, MI, USA, 28-30 September 2020 CY - East Lansing, MI, USA T2 - International Workshop on ECR Ion Sources T3 - 24 LA - english AB - An upgrade of RHIC EBIS, the extended EBIS, is presently under development at Brookhaven National Laboratory to increase the intensity of the Au³²⁺ ion beams by 40%’50% to 2.1 ’ 10⁹ Au³²⁺ ions/pulse at the booster ring entrance. Generation of intense beams of polarized 3He²⁺ ions with up to ~ 5 ’ 1011 ions/pulse for the RHIC and the future electron’ion collider is a goal of the EBIS upgrade project as well. Ultra-high vacuum is extremely important for stable and reliable operation of EBIS/T devices. We have developed a linear pumping module based on the ZAO NEG unit commercially available from SAES Getters. This pumping system will be used for the Extended EBIS Upgrade which is presently under development at BNL. A ZAO NEG module has been modified to be heated up to 600 °C by passing up to 120 A of DC current through a stainless-steel cage for required NEG activation and reactivation temperature cycles. A method of pumping speed measurements using pulsed gas injection into the vacuum chamber has been developed and used for characterization of the ZAO NEG-based linear pumping system.
