2Use of the Big Liquid Argon Spectrometer Bars for Neutrino and Cosmic-Ray Studies

VB Anikeev,SV Belikov,SN Gurzhiev,AG Denisov,SP Denisov,NN Fedjakin,VI Kochetkov,VM Korablev,VI Koreshev,VV Lipaev,SV Los,VN Mikhailin,

The design of the fine grained 300 t liquid argon calorimeter BARS is described. The BARS electronics include about 30 K channels of low noise amplifiers and ADCs. The DAQ system makes it possible to select channels with signals above the chosen threshold. 48 scintillation hodoscopes placed inside the liquid argon are used to form the first level trigger. The total number of scintillation counters in liquid argon is 384. Sums of ionization signals are used to produce the second level trigger. Results of the first use of liquid argon calorimetry for the measurements of tagged neutrino interactions, cosmic-ray muon spectra and composition of extensive atmospheric showers are discussed.

3First Investigation of the Gas Ionization Electromagnetic Calorimeter Using Heavy Freon C3f8

YV Gilitskii, SP Denisov,AY Dushkin,VN Mikhailin,VA Onuchin,AP Soldatov,VV Sytnik,IV Shein

First experimental results for a gas ionization electromagnetic calorimeter using heavy freon C3F8 as a ''fast'' working gas are presented. The density of C3F8 is 4.4 times that of the 90% Ar + 10% CF4 gas mixture used previously.
