The LEETECH (Low Energy Electron TECHnique) electron test beam facility has been designed and manufactured at Laboratoire de l’Accelerateur Lineaire (Orsay, France). Energy of electron beam can vary from 100 keV to 5 MeV. Two measurement sessions with application of the diamond sensor and the Micromegas/InGrid tracking module characterization were performed. Complete facility design with the Geant4 simulation, mechanical design, implementation of remote control and readout system is presented. An option to generate the electron bunches including a few particles only is confirmed, the obtained results are in rather good agreement with the corresponding simulation within uncertainty. Main results with the preliminary analysis from the Micromegas/InGrid measurement session are also presented.

Results of simulation and measurements on the LEETECH facility with quartz Cherenkov detector prototype which is one of the candidates for the time-of-flight technique implementation at the upgraded BES-III and HIEPA (China) experiments are presented. The dependence of the electrons time variation from opening of the collimators is determined. The results of the dependence of time registration of Cherenkov exposure from spatial displacement of the quartz bar with the size 20 ⨯ 40 ⨯ 200 mm are presented. Time resolution of 50 ps was measured during the experiment. The obtained results are in agreement with the expected and demonstrate the possibility of the application of quartz detectors of this type for determining the kinds of the particles.

A new versatile facility LEETECH for detector R&D, tests and calibration is designed and constructed. It uses electrons produced by the photoinjector PHIL at LAL, Orsay and provides a powerful tool for wide range R&D studies of different detector concepts delivering “mono-chromatic” samples of low energy electrons with adjustable energy and intensity. Among other innovative instrumentation techniques, LEETECH will be used for testing various gaseous tracking detectors and studying new Micromegas/InGrid concept which has very promising characteristics of spatial resolution and can be a good candidate for particle tracking and identification. In this paper the importance and expected characteristics of such facility based on detailed simulation studies are addressed.
