Talk:Ionization chamber

message: Someone needs to add a redirect so that searching for "ion chamber" will redirect to "ionization chamber". Colinsweet (talk) 05:25, 30 January 2008 (UTC)

text: I think the term 'ionization chamber' is sometimes used in two different senses - in one sense referring specifically to these low voltage type detectors, and in another sense as a more general umbrella term for chambers operating at whatever voltage that detect radiation/particles by the ionization they cause.

thread_title:  Ion Chamber redirect 

message: I have overhauled the article to remove confusion with Geiger-Muller and proportional devices. There is an additional graphic to more clearly show generation of ion pairs and ion drift. Repeition and deviation have been removed and fragmentary edits have been consolidated. The article now takes the approach of a simple guide to the physics, and practical construction and uses of the ion chamber as a radiogical instrument. Dougsim (talk) 14:24, 3 November 2012 (UTC)

message: The present text, in the paragraph starting with "The electric field also enables", confuses current mode with ionization chamber mode. One has nothing to do with the other. An ionization chamber is a gas filled radiation detector operated at a sufficient internal electric field to collect all (or nearly all) of the ions that are produced in the gas by the direct action of the incident radiation, avoiding ion recombination, but at an internal electric field below the onset of gas multiplication. A gas filled radiation detector operated in the proportional gas multiplication region is termed a "proportional chamber". In principle a gas filled detector can be operated in either ionization mode or proportional mode depending on the applied voltage, but the design and application of the device usually favors one of these modes over the other. 
Current mode implies measurement of the average total ion production in the chamber gas by the average electric current induced in the external electrical circuit. Current mode stands in opposition to pulse counting mode in which each individual detection "event", such as an alpha particle passing through the chamber gas, produces a small cloud of ionization which can be read out electrically as a pulse and recorded as an increment on a counter. In principle an ionization chamber can be operated in either current mode or pulse mode, the main difference being the method for reading out the signal. Similarly, proportional chambers can be operated in either current mode or pulse counting mode.  — Preceding unsigned comment added by Shefsky (talk • contribs) 01:14, 3 September 2013 (UTC)
thread_title:  Confusion between current mode and ionization chamber mode 

message: I don't want to stand on one side or the other as to the "correct" spelling, but this article is very inconsistent.  To make things consistent with the article title, I am going change all occurrences of "ionisation" to "ionization" (and similarly for "ionizing" etc), unless I hear strong opinions to the contrary.  Just thought I would bring it up here first. LaurentianShield (talk) 22:45, 3 August 2014 (UTC)
