WG: [ RadSafe ] Neutron flux from electron accelerators

[Rainer.Facius at dlr.de]

Sorry for the goof-up:
 
Of course, it is the Bremsstrahlung effect instead of the Compton effect - although an inverse Compton effect also exists which in principle which could contribute.

In technical terms: The electrons produce photons by the Compton effect which in turn can liberate nucleons (protons or neutrons) via Chadwick-Goldhaber's nuclear photo effect - appropriate energies and materials provided.

Hello radsafers,



                I am curious how neutrons are produced in an electron
(and positron?) accelerator. Can anyone offer a brief explanation?



Thanks in advance,
