Electromagnetic delay line readout for proportional wire chambers

Wire Arrays Vs Vidicons: a Comparison of Large Wire Arrays with Optical Spark Chambers Using Vidicon Readout

Digitized spark-chamber systems using wire arrays are being used for increas­ ingly complex types of events; their chief virtue is the provision of "on-line II informa­ tion on the progre ss of the experiment, which we inte rpret as rapid enough to aIIow the results obtained to influence the future course of the experiment. Such on-line operation can also be obtained by several other methods fo...

Drift and Proportional Tracking Chambers

A comprehensive study of rate capability in Multi - Wire Proportional Chambers

Systematic measurements on the rate capability of thin MWPCs operated in Xenon, Argon and Neon mixtures using CO 2 as UV-quencher are presented. A good agreement between data and existing models has been found, allowing us to present the rate capability of MWPCs in a comprehensive way and ultimately connect it with the mobilities of the drifting ions.

طراحی، شبیه‌سازی و ساخت یک نمونه اتاقک گازی پرتو ایکس حساس به موقعیت

In this paper a one dimentional position-sensitive X-ray gas detector has been designed, simulated and constructed based on Multi Wire Proportional Chamber (MWPC) with delay line position readout. These kinds of detectors are useful in soft X-ray imaging and are capable of being extended to two dimensions position readout easily. The position resolution of this detector is estimated to be 230µm...

Multiwire proportional chambers in the HERMESexperimentA

The multiwire proportional chambers of the HERMES spectrometer are described. The chambers are located in the spectrometer magnet gap which imposed strong constraints on their design. Non-ammable gas mixture of Ar(65%), CO 2 (30%) and CF 4 (5%) is successfully used with an eeciency plateau 500V wide. The readout is performed by means of the recently developed LeCroy PCOS4 acquisition system upg...
