Abstract
The CHARM II Collaboration is building a massive, fine-grained and low-density detector for the study of neutrino-electron scattering. Its target calorimeter consists of 441 detector planes with 155 232 plastic streamer tubes with digital readout of the wires and analog readout of external pickup strips. At the time of this report, about 25% of the calorimeter planes were equipped with electronics. Results on the performance of these tubes are presented as obtained with cosmic-rays and with electron and pion beams. We have also investigated the use of water vapour as an additive to the gas to suppress coating of the anode wires. The use of water would be of particular importance when using the tubes in a high-rate environment.
