  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.
