Description

The hadron cooler is an essential system for achieving high luminosity in the Electron-Ion Collider (EIC). The required electron source parameters exceed the current state of the art. We are conducting an electron-source R&D program aimed at producing an average current above 75 mA with bunch charges of 1–3 nC.
This proceeding outlines the high-voltage design of a DC gun operating at 500 kV, with conditioning capability up to 600 kV. The design incorporates several unique features, including an inverted ceramic insulator at this voltage level, active cathode cooling, and large single-crystal multi-alkali photocathodes grown on silicon carbide substrates. This paper presents recent progress on gun construction, commissioning plans, and preliminary major components test results.
