Abstract
We have designed, built, and tested a high-resolution streamer chamber that employs a novel diffusion suppression scheme. The chamber operates at 60 atm, uses a few-nanoseconds-wide 250 kV high-voltage pulse, has a maximum repetition rate of 10 Hz, and has an active volume of 13.5 × 4.5 × 0.7 cm3. Under these conditions we measure the rms deviation of streamer centers from fitted track trajectories to be about 12 ωm in space, and a two-track resolution of approximately 50 ωm.
