bremsstrahlung emission production in secondary targets

Hi,

I am interested to investigate the possibility of the generation of bremsstrahlung emission in the laser plasma interaction.

Two references which are mentioned at the manual of EPOCH discuss about the generation of energetic electrons which are produced due to the interaction of an intense laser beam with a solid target. the transport of such energetic electrons in front of and within the solid target may produce bremsstrahlung emissions.

In our case, the interaction of an intense laser beam with a solid target accelerates protons at the rear side of the target. These accelerated protons move about several millimetres and then interact with a secondary solid target which could produce bremsstrahlung emission within the second target.

The difference is that, here, I focus on protons (not electrons) . Moreover, at the references the energetic electrons directly interact with the main target while in my case protons should move away from the rear side of the main target and then interact with a secondary target.

would you please tell me can I use EPOCH to study this phenomenon?

Thanks in advance,

Current EPOCH only includes support for bremsstrahlung emission created through the interaction of incident electrons and other matter. It's possible in the future we can add proton induced bremsstrahlung, but I'm not able to offer any timescale for that work to be carried out.

Regarding the second half of your question, the bremsstrahlung module doesn't differentiate between 'targets'. It simply calculates the local bremsstrahlung emission due to the interaction of electrons and and other material present.
