Em. Gushchin et al., FAST BEAM CHAMBERS OF THE SET-UP ISTRA-M, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 351(2-3), 1994, pp. 345-348
The characteristics of narrow gap proportional chambers are presented.
These chambers are applied in a beam part of the ISTRA-M apparatus in
which very rare K- decays are studied.
