We designed and built a new test facility to investigate signal induced by electrons in the 0-3.5 MeV in the JUICE UVS and MAJIS instruments. The facility uses radioisotopes sources to produce low flux of electrons (<6000 electrons/cm².s). We present the facility, its capabilities and the results of measurements on UVS and MAJIS.
