SIRIUS is an electron accelerator platform of the LSI Laboratory which offers the possibility to irradiate with high electron energy/current and low temperature. Since it came into operation, the accelerator is used as a powerful means of studying, analysing and designing a wide range of materials.
Notice that financial participation is due for the irradiations and contact the facility at sirius@polytechnique.fr before submitting your EMIR&A project.
The important particularity of SIRIUS :
The NEC Pelletron accelerator of adjustable energy (150 KeV – 2.5 MeV) and current (10 nA – 50 µA).
The accelerator is equipped with several irradiation set-ups which allow measurements even at low temperatures (20 K).
The two beamlines of the platform allowed to place the beam in two different experiment in a short time.
Some in situ measurement are available on SIRIUS
Electrical : conductivity, Hall effect, I-V curves
Optics : absorption, photoluminescence (with time resolution), cathodoluminescence
Structural : Raman
Magnetic : Electron Paramagnetic Resonance (post-irradiation, in situ under development)
