Abstract
The design of the fine grained 300 t liquid argon calorimeter BARS is descr ibed. The BARS electronics include about 30 K channels of low noise amplifi ers and ADCs. The DAQ system makes it possible to select channels with sign als above the chosen threshold. 48 scintillation hodoscopes placed inside t he liquid argon are used to form the first level trigger. The total number of scintillation counters in liquid argon is 384. Sums of ionization signal s are used to produce the second level trigger. Results of the first use of liquid argon calorimetry for the measurements of tagged neutrino interacti ons, cosmic-ray muon spectra and composition of extensive atmospheric showe rs are discussed.
