Talk:Cherenkov detector

Merger proposal
It seems plainly obvious to me that Ring-imaging Cherenkov detector should be merged into Cherenkov detector. Both articles are unsourced stubs that need a lot of work, and one is a sub-category of the other. The principle of Cherenkov detection is explained to varying degrees in both. For Cherenkov detector it takes up the majority of the article!! --EvilFred (talk) 15:35, 30 October 2012 (UTC)


 * I disagree. Sub-category relation in itself is no reason for merging. Ring-imaging Cherenkov detector and Cherenkov detector are valid separate articles. Certainly the latter still needs quite some TLC, while the former has been significantly expanded in the last few months. -- KlausFoehl (talk) 14:48, 15 March 2013 (UTC)

article structuring - detector aspects
I put the following aspects up for discussion...

what produces the Cherenkov light?
 * Cherenkov light produced by primary particle
 * Cherenkov light produced (also) by secondary particles (incoherent emission, example electromagnetic shower or coherent emission, example Askaryan effect)

what electromagnetic band is detected:
 * radiofrequency
 * visible light
 * UV light

what information is used?
 * binary signal, light/no light
 * amount of light
 * direction of light

and then relating to the above, what Cherenkov detector types exist (incomplete list):
 * threshold
 * succession of several thresholds
 * differential
 * light output
 * RICH
 * calorimetry

...waiting for your fellow authors' feedback. -- KlausFoehl (talk) 15:07, 15 March 2013 (UTC)

articles Cherenkov detector and Cherenkov radiation
There are articles Cherenkov detector and Cherenkov radiation. I think that an overlap in contents is unavoidable, but I wonder: should some content in Cherenkov radiation be better placed in the Cherenkov detector article?

I do not think that the two articles should be merged.

Waiting for other opinions. -- KlausFoehl (talk) 16:05, 19 April 2013 (UTC)

A black hole self-detects
A black hole, when consumes mass, generates patterns in its spectrum of electromagnetic emissions, and that acts as a Cherenkov (self-)detector.

note that:
 * 1) the "black hole system" isn't only its core
 * 2) layer components of the "black hole system" allow particles to travel faster than light within them
