Direct detection of charged particles with SiPMs

0 Electro - Optical Detection of Charged Particles

We have made the first observation of a charged particle beam by means of its electro-optical effect on the polarization of laser light in a LiNbO3 crystal. The modulation of the laser light during the passage of a pulsed electron beam was observed using a fast photodiode and a digital oscilloscope. The fastest rise time measured, 120 ps, was obtained in the single shot mode and was limited by ...

Detection Of Energetic Charged Particles During Electrolysis

By the use of Cr-39 particle track detectors immersed in the electrolyte, we confirm that a nuclear reaction of as-yet unknown nature can take place during electrolysis. With Li2SO4 dissolved in D2O or H2O and either Pd or Ni as cathodes, a very large statistical difference in nuclear track generation is found between detector chips immersed during electrolysis and the control chips immersed in...

Direct Detection of Dark Matter Particles

Experimental observations and theoretical arguments have pointed out that a large part of the Universe is composed by Dark Matter particles. This motivates experimental efforts to investigate the direct detection of these particles with detectors placed in underground laboratories. In this paper a short review of some used techniques will be presented. Particular care will be given to the resul...

2 00 0 First Electro - Optical Detection of Charged Particles

We have made the first observation of a charged particle beam by means of its electro-optical effect on the polarization of laser light in a birefringent crystal. The modulation of the laser light during the passage of a pulsed electron beam was observed using a fast photodiode and a digital oscilloscope. The fastest rise time measured in a single shot, 120 ps, was limited by the bandwidth of t...
