Description
The PERLE project aims to build a high power electron Energy Recovery Linac (ERL) demonstrator (5 MW) to develop and apply the energy recovery technique in a multi turn configuration. In an initial intermediate phase PERLE will operate in a single turn mode with a 5 mA beam at 89 MeV. In its final layout the machine will run in a three turn mode, delivering a 20 mA electron beam at 250 MeV. These challenging parameters make PERLE a unique multi turn ERL facility operating in an unexplored power regime, enabling the study and validation of a broad range of accelerator phenomena and paving the way for future, larger scale ERLs.
The principal advantage of ERLs lies in their ability to return the power of a spent beam to the RF system. This recovered power can then be used for acceleration with practically no losses, thereby markedly improving the sustainability of high power machines. One of PERLE’s goals is to assess the overall sustainability of a multi megawatt ERL. In this work we present the current status of the studies carried out to evaluate the total electrical power consumption (“plug to grid”) of the accelerator for various operating modes—both single turn and multi turn—and relate this consumption to the average beam power delivered at the interaction point. We also discuss the power balance of a high power multi turn ERL and compare its efficiency with that of conventional accelerator types; e.g., linacs (with recirculation).
