Source: WordNetMost of these experiments required the reduction of the cosmic ray muon flux in order to be successful, and the group necessarily became expert in the operation of deep underground laboratories. Frederick Reines
Compared to electromagnetic relays, they may be falsely triggered by transients and in general may be susceptible to damage by extreme cosmic ray and EMP episodes. Source: Internet
Consequently, many more cosmic ray bursts must be happening than just the small fraction seen by astronomers. Source: Internet
As the cosmic ray speed decreases due to deceleration in the stack, the ionization increases along the path. Source: Internet
He graduated on cosmic ray experiments in 1957 with Marcello Conversi. Source: Internet
At the top of the plastic stack the ionization is less, due to the high cosmic ray speed. Source: Internet
