Delay line readout technique applied to proportional chambers using electronegative gas mixtures
The delay line readout technique was adapted to proportional chambers using electronegative gas mixtures. This requires lines with improved rise time, but allows somewhat shorter delays; at the same time, we improved the two-pulse resolution. Our new line is 55 cm long, has a delay to rise time ratio of 50 for a delay of 2.1 $mu$s; two pulse resolution in the middle of the line is of the order of 15 mm for equal amplitude pulses. We also investigated aluminum core and printed circuit delay lines. We found that the first ones are well suited for low to medium delays with medium two pulse resolution; the second ones are adapted to low delays and may have extremely good delay to rise time ratio in the differential stripline configuration.
