My father Eugene (Bud) Cowan used to build cloud chambers. Here are some photos.

The EU-funded Training Network INSIGHTS.

Some outreach: RHUL Evening Lecture 8 Dec 2017, Using Machine Learning at the Large Hadron Collider (podcast and slides); Antimatter: the picture that was not reversed. Talk given to the West of London Astronomical Society, 12 March 2007 (ppt, pdf).

RHUL sees the 2004 Venus Transit. Link to Guardian with our jet + planet photo. And here is a related talk I gave at the IoP Physics Update Course at RHUL, 9 April 2005.
