Description

The Electron–Ion Collider (EIC) requires a 750 MeV normal-conducting electron pre-injector operating at 30 Hz and delivering polarized electron bunches with charges of 1–2 nC. The RF system must provide bunching, capture, and acceleration while meeting the performance and reliability requirements of the EIC injector. The proposed RF architecture consists of a 197 MHz bunching cavity, two 1.3 GHz L-band normal-conducting structures, and fourteen 3 m, 2.856 GHz S-band traveling-wave accelerating structures. The L-band section provides low-energy capture and acceleration to approximately 14 MeV, followed by the S-band linac accelerating the beam to 750 MeV. The high-power RF system employs pulsed klystrons, with pulse compression used in the S-band system to reduce the required klystron peak power. Low-level RF controls are based on the modular EIC common hardware platform. This presentation will describe the overall RF architecture, the L-band and S-band accelerating systems, high-power RF and LLRF implementation, and key design choices being made to provide a scalable and reliable RF system for the EIC electron pre-injector.
