Electron irradiation facility for the study of radiation damage in large solar cell arrays in the energy range 0.5 < E <= 5 MeV
In this work, a description is presented of the use of an accelerator facility to uniformly irradiate with electrons large samples (of the order of m(2)) in the energy range from 0.7 to 5MeV, and currents ranging from hundreds of micro amps to tens of milliamps. The accelerator has a scanning system that allows for large area irradiations. Reference is made to a sample handling system used for solar cell irradiations and a Faraday Cup designed to measure the electron fluence in this facility. Measurements performed with these systems show a typical irradiation area of 6200 cm(2) and fluence values of 10(13) e/cm(2) achieved in about 60 s of irradiation time. (c) 2004 Elsevier B.V.
