New versatile platform based on the low energy electron beam delivered by the PHIL photoinjector

Abstract

New flexible facility is proposed to be constructed at the photoinjector PHIL at LAL, Orsay. The proposed setup will provide a powerful tool for wide range R&D studies of different detector concepts using “mono-chromatic” samples of low energy electrons with adjustable energy and intensity. Main detector concepts to be studied with the new platform range from large area radiation resistant precision tracking, Micromegas/InGrid concept, and particle identification, to the beam monitoring using bent crystal technique. Other immediate platform applications are scintillator measurements for the neutrinoless double-beta decay experiments (SuperNEMO), diamond sensor tests as profile monitors and as tracking devices for the ATF2 project. In the framework of by-product physics studies, dE/dx for non-relativistic electrons will be measured using Micromegas/InGrid detector for single primary electron cluster reconstruction. Main characteristics of the setup and simulation results are addressed by this paper. Keywords: Micromegas/InGrid, photoinjector PHIL, beam monitoring, precision tracking.
