A Liquid Scintillator Detector for the Carpet-3 Experiment

详细

A new liquid scintillator detector created at the Carpet-2 air shower array of the Baksan Neutrino Observatory of the Institute for Nuclear Research is described. The detectors of this type will be placed in the modules of the ground-surface part of the new Carpet-3 array, which will be used to study galactic diffuse γ rays with energies of primary gamma rays E_γ > 100 TeV. For this detector the most probable amplitude of the anode signal from extensive air showers (EAS) is approximately 13 mV, while the energy resolution is ~42%. The inhomogeneity of the light-collection coefficient is 0.26. The number of photoelectrons at the photocathode is approximately 360. The detector is easy to operate and costs less than the traditional scintillation detectors used in our air-shower array.
