Description
The Strong Hadron Cooling (SHC) for electron ion collider project requires a state-of-the-art high brightness DC electron gun. The gun is required to deliver high average current (98.5 mA), 1 mm∙mrad normalized transverse emittance and 1-2.5 nC bunch charge. In this paper, we describe the high voltage design of a DC gun with an operating voltage of 550 KV, to be conditioned up to 600 KV. Unique features of this gun includes the use of inverted ceramic in this level of voltage, active cooling for the cathode and use of large/single crystal multialkali cathode grown on Silicon-Carbide substrate. A test beam line for high current test is also described.
