N2 - eRHIC, a future electron-hadron collider proposed at BNL, will collide high-intensity hadron beams from one of the existing rings of RHIC with an electron beam from a multi-pass 21.2 GeV superconducting RF (SRF) Energy Recovery Linac (ERL). A novel approach to the multipass ERL, utilizing a non-scaling FFAG, was recently proposed [1]. It has many advantages over the previous designs including significant cost savings. The current design has up to 16 passes in two FFAG rings. To mitigate various beam dynamics effects, it was proposed to lower RF frequency of the SRF linac from 704 MHz used in the previous design. In this paper we consider different effects driving the frequency choice of the SRF ERL and present our arguments for choosing a lower RF frequency.
