Two New Parallel-plate Ionization Chambers for Electron Beam Dosimetry
-Two parallel-plate ionization chambers were projected, constructed and evauated for use in high energy electron beams. They were constructed using the two plastic materials recommended for clinical dosimetry protocols, i.e. acrylic and polystyrene. Both chambers have cylindrical shape with entrance windows in aluminized Mylar and they are open to the air. The acrylic chamber has a 2 mm air gap...
متن کاملResistive Plate Chambers in ATLAS
The ATLAS first level muon trigger is based, in the rapidity region ( v ( 5 1.05, on fast and finely segmented gaseous detectors, Resistive Plate Chambers (RPCs) . A prototype of a small scale RPC trigger tower has been assembled and tested. We present results on efficiency, time resolution, cluster size and collected charge. The detectors, filled with a non-flammable and environment-safe gas m...
متن کاملDetailed models for timing and efficiency in resistive plate chambers
We discuss detailed models for detector physics processes in Resistive Plate Chambers, in particular including the effect of attachment on the avalanche statistics. In addition, we present analytic formulas for average charges and intrinsic RPC time resolution. Using a Monte Carlo simulation including all the steps from primary ionization to the front-end electronics we discuss the dependence o...
متن کامل- iii - LIQUID XENON FILLED WIRE CHAMBERS FOR MEDICAL IMAGING
In 1968, Luis Alvarez suggested that a high-resolution multiwire particle detector could be developed using a thin layer of liquified noble gas as the detection medium. After key problems in chamber construcbon, purification, and readout had been solved, a spatial resolution of 15 fl. rms was demonstrated. Work is in progress to build high-resolubon chambers and lTIeasure their properties for p...
متن کاملA New Single Wire Readcut System-for Spark Chambers*
A new, conceptually very simple, single wire readout system for spark chambers in strong magnetic fields is described. (Submitted to Nucl. Instr. and Methods. ) *Work supported in part by the U. S. Atomic Energy Commission. Prepared under Contracts AT(04-3)-5 15 and AT(ll-l)-68 for the San Francisco Operations Office, U. S. Atomic Energy Commission.
