Quenching properties of gas mixture in glass RPC operated with streamer mode
Quenching properties of gas mixture in a resistive plate chamber operated with streamer mode were investigated using optical image taken by the CCD camera and signal pulse waveform recorded by the digital oscilloscope. We have tested four quenching gases: C2H2F4, C2F6, CBrF3 and SF6. Streamer size, brightness and induced charge linearly depend on the ratio of Ar to quenching gas and their slope...
متن کاملMobilities of positive ions in some gas mixtures used in proportional and drift chambers
2014 We have measured the mobility of positive ions in several gas mixtures frequently used in proportional and drift chambers, namely Ar-(OCH3)2CH2, Ar-(OCH3)2CH2-IsoC4H10, Ar-CH4, and Ar-CO2. In all gas mixtures considered, Blanc’s law of positive ion mobility has been verified, except for a very small methylal concentration in argon-isobutane-methylal. The law permits the calculation of ion ...
متن کاملStudy of a self quenching streamer mode in pure gases of DME and isobutane
A self quenching streamer (SQS), or limited streamer mode has been studied in single wire chambers with cross-sections 12·12 mm and wire diameters 15, 25 and 50 μm. Chambers were filled with either pure dimethyl ether (DME) or isobutane gases and irradiated with Gd alpha and Fe x-ray sources. Clear transitions from a proportional to 100% SQS mode were observed on all three diameter wires with b...
متن کاملQuenching of self-excited vibrations
Stable normal-mode vibrations in engineering can be undesirable and one of the possibilities for quenching these is by embedding the oscillator in an autoparametric system by coupling to a damped oscillator. There exists the possibility of destabilizing the undesirable vibrations by a suitable tuning and choice of nonlinear coupling parameters. An additional feature is that, to make the quenchi...
متن کاملQuorum quenching for the management of dental plaque microbes
In the present study, variation among different bacterial strains was observed in the plaques of tobacco chewers (TC) as compared to those from normal persons (non tobacco chewers) (NTC). Bacterial strain J1 (dominant in the plaques of NTC) did not initiate the process of adhesion (biofilm formation) until it appeared to have reached a required population density necessary for the production of...
