fast electron การใช้

Much early experimental work on Rydberg atoms relied on the use of collimated beams of fast electrons incident on ground-state atoms.
Fast electrons which move at a large fraction of the speed of light have a mean free path up to 100 times longer.
The similarity theory allows deriving non-trivial power-law scalings for the energy of fast electrons in underdense and overdense plasmas.
Henri Becquerel himself proved that beta rays are fast electrons, while Rutherford and Thomas Royds proved in 1909 that alpha particles are ionized helium.
In February 2013, Samuel Ting acknowledged that he would be publishing the first scholarly paper in a few weeks, and that in its first 18 months of operation AMS had recorded 25 billion particle events including nearly eight billion fast electrons and positrons.
