What is an electrons mass and energy while being accelerated? What about radiation in circular accelerators?
Questions: I read in the textbook by Ohanian (Principles of Physics) that at SLAC electrons are accelerated to a speed of 99.999 999 994 8% of the speed of light, or 0.999 999 999 948c. I would like to know the following: 1. The actual combined applied voltage used to attain this speed? 2. The mass of the electrons at this speed expressed in kg, as the electrons exist the accelerator, and just before a collision? 3. The energy of the accelerated electrons expressed in MeV? (Or, is the energy of the accelerated electron deduced from applied voltage?) I read somewhere that in linacs, as opposed to circular accelerators, electrons do not lose gained energy due to acceleration. Was this the case in this example? If there were a loss, what would have been its magnitude in MeV or in percentage? Thank you for your help. Sincerely Boris Milvich Answer: Hi Boris, here are some answers to your questions: 1) The applied voltage is not done in one step. Simply put, we can boost the kinetic energy
