Research paper thumbnail of A nonflammable gas mixture for plastic limited streamer tubes

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1989

The gas mixtures presently used in plastic limited streamer tubes ("Iarocci tubes" or LSTs) have ... more The gas mixtures presently used in plastic limited streamer tubes ("Iarocci tubes" or LSTs) have a high hydrocarbon content and are very flammable when mixed with air, posing a potential safety hazard in modern large underground experiments. The S$ Warm Iron Calorimeter group has therefore made an extensive investigation of nonflammable ternary mixtures based on COZ, Ar and various hydrocarbons.

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1989

The safety issues are therefore very relevant for large-volume underground experiments. We have found a set of completely safe (i.e. nonflammable) ternary mixtures of the kind Ar + hydrocarbon + CO 2 containing less than -5% of Ar and less than ~ 10% of hydrocarbon. We tested C4H10 , C5H12 and C6H14 as quenching agents. The main characteristics of the various mixtures have been measured: singles (untriggered) counting rate versus high voltage and with different dead times, and average charge. The stability of these mixtures is good, and their spurious streamer activity is compared with the standard binary or ternary mixture. We studied in particular the combination Ar(2.5%)+ C4H10(9.5% ) + CO2(88% ). All the data suggest that this or a similar gas mixture can successfully replace standard flammable mixtures both in tracking devices and hadron calorimeters. * Permanent address: INFN, Sezione di Padova, Italy. 0168-9002/89/$03.50

For various combinations of CF4 + hydrocarbon and CF4 + hydrocarbon + Ar we measured the singles counting rate plateau, the charge spectrum and the average drift time over the cell. The hydrocarbons used were respectively isobutane, n-pentane and n-hexane. The stability of these mixtures is good, and their spurious streamer activity is compared with the standard binary or ternary mixture. The drift velocity is at least twice as high as in the standard mixtures.
