Which one is more efficient in generating high energy Gamma rays?

[QUOTE="gleem, post: 6406322, member: 298988"] That is the [B]average[/B] energy of the x-rays, the maximum energy is 22MeV. Efficiency would generally be measured as the ratio of the total energy of the useful flux of radiation to the energy used to produce this flux. Bremsstrahlung production itself is an inefficient process and the same for any method for accelerating electrons. The difference is in the energy losses due to the different methods of accelerating the electrons. I am not very familiar with the Hermes or laser systems but let me make a few remarks. As it is presented the advantage of the laser based bremsstrahlung generator is that it is much smaller than other methods to accelerate the electrons. Linacs have losses because they use electric power to drive high frequency amplifiers to produce the electric fields for the waveguide that accelerate the electrons. Lasers must excite the lasing medium to produce the high intensity light beams that produce the electric fields. Not all this energy goes into producing the accelerating field. Their energy losses are different. Although both are pulsed systems the linac has(currently?) a higher repetition rate compared to the laser. The Los Alamos Hermes is a different beast producing a hyperintense electron pulse to produce the bremsstrahlung. You really cannot say it is a beam since its rep rate is only 7 pulses per day but each pulse produces a heck of a lot of x-rays. So will the electric bill be less for a plasma wake field accelerator so the same thing as a linac? I do not know. [/QUOTE]
