Delay-line readout of anode planes in proportional chambers

Drift and Proportional Tracking Chambers

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...

prediction of ignition delay period in d.i diesel engines

a semi-empirical mathematical model for predicting physical part of ignition delay period in the combustion of direct - injection diesel engines with swirl is developed . this model based on a single droplet evaporation model . the governing equations , namely , equations of droplet motion , heat and mass transfer were solved simultaneously using a rung-kutta step by step unmerical method . the...

Effects of Secondary Electron Emission on Charge Pulses from a Z-Stack Microchnnel Plate Photon Counting Detector with a Crossed Delay Line Anode Readout

A study of the effects of secondary electron emission on charge pulses from a microchannel plate (MCPs) photon counting detector with crossed delay line (CDL) anode readout is presented. The detector is a two-dimensional photon counting detector with fast count rate and good spatial resolution being developed at Los Alamos National Laboratory. The CDL anode is constructed of two orthogonal plan...
