A video showing the first 15 min of set-up of the new cloud chamber. It can display particles in less than 7 minutes and can work with no assistance during 2 hours. It recquire only methanol and eletricity to observe the particles. I think I have reached the end of my research as the quality of the particles can't be increased (in terms of sharpness and reactivity). It was a very long process (nearly 9 years) to masterize all the parameters to get the perfect equilibrium with a compressor cooled machine. This is by far the most complicated experience I had to stabilize since my beggining in the field early 2010. Thanks for watching and your interest during these years =) , Cloudylabs.fr
