Charged Particle Detection 1David Futyan Energy Loss of Charged Particles in Matter For moderately relativistic charged particles other than electrons ( heavy charged particles ) almost all the energy loss is through Coulomb interaction with the atomic electrons.
{"Image DocumentName": "Energy Loss of Charged Particles in Matter", "Image ImageDescription": "For moderately relativistic charged particles other than electrons ( heavy charged particles ) almost all the energy loss is through Coulomb interaction with the atomic electrons. This interaction is inelastic: The energy transferred to the electrons causes them to be either: ejected from the parent atom (hard collision) - ionization. or: excited to a higher energy level (soft collision) - excitation. Energy transferred in each collision much less than particle\u2019s total KE, but no. of collisions / unit length is very large. e.g. 10MeV proton completely stopped by 0.25mm of Cu.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
