Study of Dimethyl Ether for Limited Streamer Tubes*
نویسنده
چکیده
Position resolution and lifetime have been studied for one-atmosphere D\IE in half-inch diameter aluminum tube chambers operated in the limited streamer mode. The radial resolution was measured by timing to be CT, = 73 pm. The longitudinal resolution was measured by charge division to be < 0.3% of the wire length. No significant gain changes were seen after 12 C/cm.

Study 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 کاملThe Limited Streamer Tubes of the Sld *
A large hadron calorimeter and muon tracking device using plastic streamer tubes has been constructed in the iron flux-return structure for the SLD detector at SLAC. Various studies of the operating characteristics of the streamer tubes of this system are presented. Emphasis is placed on the tracking capabilities of the device and on the optimization of the high voltage and readout electronics....
متن کاملLimited Streamer Tube and Capacitor Testing for BABAR Detector
Testing of Limited Streamer Tubes (LSTs) has been conducted on the first set of LSTs meant for installation in the BABAR detector. The tubes are kept under high voltage (between 5 and 6 KV) as often as possible to ensure their durability. Three tests were conducted: signal charge, leak and radioactive source. Testing is conducted to ensure that no damage occurred during transport of the LSTs fr...

Peter Diakow Department of Mechanical and Materials Engineering, Queen’s University, Kingston, Canada Synopsis Dimethyl-ether (C2H6O) a common hydrocarbon is increasingly being used as a transportation fuel and as an aerosol propellant, very limited explosion safety data is available for this fuel. Experiments were performed to determine the detonation characteristics of dimethyl-ether air mixt...
متن کاملA layer of streamer tube detectors for the measurement of muons in the KASCADE central detector
For an improved detection of cosmic ray muons with a threshold of 2.4 GeV, the KASCADE Central Detector has been upgraded with a new detector component built of limited streamer tubes. Combined with the operation of two layers of multiwire proportional chambers they enable studies of the muonic component of extensive air showers at higher particle densities. Due to the pad readout system of the...
