G. Battistoni et al., RESPONSE OF PROPORTIONAL AND STREAMER TUBES TO LASER-INDUCED HIGH IONIZATION TRACKS, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 401(2-3), 1997, pp. 309-316
The use of an intense XeCl laser provided a unique way to produce larg
e primary ionization in a streamer tube. The response of a proportiona
l tube was also studied as a function of the laser intensity for calib
ration purposes and to better understand the physical processes involv
ed in the excitation-ionization mechanisms in the gas mixtures. Up to
ionization powers as large as hundreds of m.i.p, the streamer tube res
ponse was shown to be logarithmic.
