New low electron flux facility in the 0 to 3.5 MeV range for the study of induced signal in JUICE instruments: UVS and MAJIS measurements

Abstract 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 ( 2 .s). We present the facility, its capabilities and the results of measurements on UVS and MAJIS.
