The history, present situation and prospects on electron multiplication and secondary scintillation in liquid xenon and their application to radiation detectors are shortly discussed.

The Joint European Torus (JET, Culham, UK) is the largest tokamak in the world devoted to nuclear fusion experiments of magnetic confined Deuterium (D)/Deuterium-Tritium (DT) plasmas. Neutrons produced in these plasmas are measured using various types of neutron detectors and spectrometers. Two of these instruments on JET make use of organic liquid scintillator detectors. The neutron emission p...

The use and detection of radiotracers in organic and biological chemistry has benefitted from advances in the efficiency and sophistication of both the chromatographic and the radioactive detection techniques. As a result, the chromatographic separation of radiolabeled compounds, sometimes referred to as “radiochromatography,” is now carried out in many laboratories throughout the world. The ba...

Scintillation produced in liquid xenon by alpha particles and gamma rays has been studied as a function of applied electric field. For back scattered gamma rays with energy of about 200 keV, the number of scintillation photons was found to decrease by 64±2% with increasing field strength. Consequently, the pulse shape discrimination power between alpha particles and gamma rays is found to reduc...

ArDM is a new-generation WIMP detector which will measure simultaneously light and charge from scintillation and ionization of liquid argon. Our goal is to construct, characterize and operate a 1 ton liquid argon underground detector. The project relies on the possibility to extract the electrons produced by ionization from the liquid into the gas phase of the detector, to amplify and read out ...

After a short introduction to solar neutrino physics, this paper describes the design concept and expected performance of the Borexino underground detector at Gran Sasso. Low background results from the Counting Test Facility, the rst phase of the Borexino project, are summarized.

Liquid argon is used as active medium in a variety of neutrino and dark matter experiments thanks to its excellent properties charge yield transport scintillator. scintillation photons are emitted narrow band 10 nm centered around 127 with characteristic time profile made by two components originated the decay lowest lying singlet, ${^{1}\mathrm{\ensuremath{\Sigma}}}_{u}^{+}$, triplet states, $...
