PENEMPA: electrons or photons?

Asked by Vittoria

Hi,

I simulate the following interaction but I have some doubts about PENEPMA and I need your help.

1) photon beam of nominal energy of 6 MeV impinging on a phantom composed of different layers: 5 cm of water, an optical fiber and finally 2 cm of water.
I need to understand what happens at the level of the optical fiber, that is the energy absorbed by the fiber. It's possible can put the detectors between two layers?

2) the incident energy that I have to defined into the first panel refers to photons or electrons? Why in the file "Stas & Probabilities" I find "Number of electrons simulated?"

3) If I select "substratum" what is the substrate thickness by default?

I hope I have explained my problem well

Thanks for your time.

Vittoria

pyPENELOPE was designed for electron microscopy problems. With that in mind,

1) No it is not possible to put a detector in between two layers. This could be done in the original FORTRAN code of PENELOPE, but not in pyPENELOPE

2) Incident particles are electrons in PENEPMA. In PENSHOWER (second choice of simulation), you can select electrons, positrons and photons. However, you will only get the trajectories.

3) The default substrate thickness is 3 cm.
