Compressor cooled cloud chamber running 7 hours

Running of the Cloudylabs cloud chamber during 7 hours in a cold outside environment (13°C) with few experiments. This video was recorded at the beginning of this year. Set-up : 0 to 7 min After 1 hour : 11:52 Magnetic field 12:04 After 2 hours : 13:53 Strontium 90 source 14:37 At 16:06, sorry I just hide the positon with the static image... Thoron (Radon 220) : 17:50 Proton 20:59 X, Gamma-Rays : 21:21 Refill of alcohol after 5 hours : 23:51 This is a prototype made in April 2020. I traveled this machine all over France to perform stress test. I have to make some improvements, but I guess It’s not too far from the final state. The infrared lamp should be used even if the outside temperature is warm because it help to stabilize the equilibrium. Check for more informations about the physic of nuclear particles or to contact me if you want to acquire one of this machine. Thanks for your interest !
