The SIRIUS facility, at the Irradiated Solids Laboratory (UMR 7642 CEA-CNRS-Ecole polytechnique), is an irradiation platform with high energy electrons consisting of an electron accelerator and two irradiation stations (having the possibility of carrying out irradiations at high currents and at low temperatures). The SIRIUS facility is open to a large community of users nationally and internationally and is part of the national network of accelerators for the study of irradiated materials EMIR&A.

Pelletron accelerator by NEC.

Electrons Enerigies: 150 keV – 2.5 MeV
Current (10 nA – 50 µA)

Different irradiation cells (see below)
Online measurement (see below)
Possibility to control the temperature (see below)
 

Electron beam current is measured using pico-ammeters at the output of the accelerator and along the irradiation line. The electrical charge passing through the sample section is, in turn, measured via a digital current integrator.
