Talk:Particle detector

There are two reasons why adding the extra link to ATLAS might seem a bit vain: I work on the experiment, and I wrote a lot of the article. However, as was requested in December 2004, I have been building up the ATLAS article in more detail than most detectors, precisely because it can serve as a useful illustration of how they work. Thus linking to it seems appropriate to me; but if you dissagree, feel free to discuss. -- SCZenz 21:28, 15 July 2005 (UTC)

there is BaBar too at SLAC, and it's still running Tatonzolo 19:48, 25 January 2007 (UTC)

single electron transistor and high Q optical cavitys and penning traps can detect single particles, albeit with low energy. lemma? Arnero 21:43, 22 March 2007 (UTC)

Size, mechanism?

I'm an engineer but not a particle physicist. I see pictures like this one and have a few questions:

• What's the size scale? From cloud chamber, I'm guessing it's on a human scale of inches to feet, which is a bit of a surprising coincidence given how many orders of magnitude there are between our size scale and that of the particles.
• How can we detect the path of particles since detecting a particle once involves exchanging photons (or other particles) between the particle and the detector (right?)

Thanks. —Ben FrantzDale (talk) 02:58, 8 July 2012 (UTC)
