Description
The Electron-Ion Collider at Brookhaven National Laboratory requires high-current, high-brightness electron beams for efficient ion beam cooling. We present the design and beam dynamics optimization of a normal-conducting electron linac for the Low-Energy Cooler (LEC), building on operational experience from the Low Energy RHIC Electron Cooler (LEReC) and extending performance toward the demanding EIC parameter regime.
The accelerator is designed to generate 1 nC electron bunches with average beam current up to 80 mA and final energy of 13 MeV while maintaining normalized transverse emittance below 1.5×10^(-6)m and relative energy spread better than 3×10^(-4). Start-to-end beam dynamics studies, including injector, accelerating sections, long transport, and 180 m cooling sections, were performed using PARMELA code and benchmarked against IMPACT-T and GPT codes.
The results demonstrate the feasibility of achieving an electron beam quality required for future EIC cooling applications using a normal-conducting RF accelerator approach, with potential relevance to other high-current electron beam facilities.
