Electronic circuits for recording signals from drift chambers of a neutrino calorimeter

Electronic circuits for data acquisition from the system of neutrino calorimeter drift chambers are described. The equipment contains forming amplifiers, 24-input moduli of time-to-digital converters providing the quantization of 10 ns per a count and a computer-controlled timing generator. The system equipment for 1500 signal wires are located in 8 ''Vector'' crates and provide recording of up to 64 singnals from each drift chamber plane during one accelerator beam extraction period
