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...

The purpose of this work carried out by MTA KFKI Atomic Energy Research Institute in Hungary, is to develop and validate a method for predicting the ex-core detector responses in the Russian pressurized water type VVER reactors. The time and space dependent neutron flux in the core during these measurements have been calculated by the KIKO3D nodal diffusion code. For calculating the ionization ...

NIMROD is a nearly 4pi detector system that consists of a 4pi neutron ball, 96 Ionization Chamber-Si-CsI modules in the forward 8 rings from 3.6 degree to 47 four rings with 46 CsI, Ionization Chamber and several Si detectors covering backward angles theta from 47 degrees to 170 degrees, four rings with 46 CsI, Ionization Chamber and several Si detectors covering backward angles theta from 47 d...

A novel surface ionization detector using a reducing quartz liner and a Mo emitter with a quartz enclosed internal heater for selective measurement of alkylamines by gas chromatography is designed and evaluated.

The imaging characteristics of an arc-shaped xenon gas ionization chamber for the purpose of megavoltage CT imaging were investigated. The detector consists of several hundred 320 microm thick gas cavities separated by thin tungsten plates of the same thickness. Dose response, efficiency and resolution parameters were calculated using Monte Carlo simulations. The calculations were compared to m...

Dual-energy measurements are presented utilizing a novel slot-scan digital radiographic imaging detector, operating on gaseous solid state ionization principles. The novel multimedia detector has two basic functional components: a noble gas-filled detector volume operating on gas microstrip principles, and a solid state detector volume. The purpose of this study is to investigate the potential ...

a three-step selective photo-ionization for gd155 and gd157 isotopes by pulsed laser wasevaluated numerically. due to large thermal neutron absorption cross sections, these two isotopes innatural gadolinium are good candidates as burnable poison to control reactivity early in the fuel cycleand allow extended fuel burn up. rate equations have been used to calculate the dynamics of the isotopepop...

After a short review of Q-balls properties, in this paper we discuss their interaction with matter, and their energy losses in the earth, for a large range of velocities. These calculations are used to compute the fractional angular acceptance of a detector at Gran Sasso Laboratory. Furthermore we computed the light yield in liquid scintillators, the ionization in streamer tubes and the Restric...
