MIMAC low energy electron-recoil discrimination measured with fast neutrons

Electron-nuclear recoil discrimination by pulse shape analysis

In the framework of the " ULTIMA " project, we use ultra cold superfluid 3 He bolometers for the direct detection of single particle events, aimed for a future use as a dark matter detector. One parameter of the pulse shape observed after such an event is the thermalization time constant τ b. Until now it was believed that this parameter only depends on geometrical factors and superfluid 3 He p...

Digital pulse-shape discrimination of fast neutrons and γ rays

Discrimination of the detection of fast neutrons and γ rays in a liquid scintillator detector has been investigated using digital pulse-processing techniques. An experimental setup with a 252Cf source, a BC-501 liquid scintillator detector, and a BaF2 detector was used to collect waveforms with a 100 Ms/s, 14 bit sampling ADC. Three identical ADC’s were combined to increase the sampling frequen...

MSGC test with fast neutrons

Results are presented from the exposure of a CMS performance prototype MSGC to a fast neutron beam having an average energy of 20 MeV and an intensity of 7 106 neutrons/mm2/s. A fluence equivalent to 3 years of LHC operation has been accumulated without damages to the detector. The stability of the MSGC operation in a heavily ionising particle flux is reported and the estimation of their produc...
