The high intensity polarized electron gun at MIT-Bates was designed as an injector for the linac-ring version of ERHIC.. The design implements a separate preparation chamber, load lock, large area cathode, ring-shaped beam and active cathode cooling. Very good vacuum conditions have been achieved in both the gun chamber and the preparation chamber. Reliable cathode transfer between the load lock, the preparation chamber and the gun chamber has been demonstrated. Beam tests have been conducted with a current from 50 nA to 5 mA. The results of these tests are discussed. 2018-12-12T00:00:00Z https://hdl.handle.net/1721.1/102632 full animation Vidal, Chris Animation for vacuum manipulation 2016-05-23T00:00:00Z https://hdl.handle.net/1721.1/102631 High Intensity Polarized Electron Gun Tsentalovich, Evgeni MIT-Bates in collaboration with BNL investigated the possibility of building a very high intensity polarized electron gun using some BNL R&D funds and a supplement from the DOE Office of Nuclear Physics, This proposal requests funding to continue the work of the last six years and is expected to result in final assembly and testing of a polarized electron gun with unprecedentedly high intensity. 2016-05-23T00:00:00Z
