The best photo of the cloud chamber I could find is on p.29 of this NASA presentation: http://ebongeek.com/wp-content/uploads/2012/01/Overview-of-Low-Energy-Nuclear-Reactions-LENR-as-Implemented-by-Andrea-Rossi-and-Francesco-Piantelli.pdf There are many interesting things in this presentation including a statement on p.24 that both Piantelli and Rossi have observed gammas and neutrons.
