- To determine the neck thickness I need to calculate the forward range of electrons which might be produced by the Ion beam interactions.Since the range of Ion beam itself is in Microns,Is it safe to assume that if I keep my neck thickness around 2-3mm the electrons emitted in the forward direction won't leave the cup surface?.
Dear Shahryar,
Thanks for the suggestion I already looked at ESTAR database.The problem in my case is the maximum energy of electrons is 330eV whereas ESTAR database is not available below MeV range!
What is the energy of your electron?
Is it 300 keV or 330 eV?
Your question is not clear.
From the ESTAR, the stopping range of the electron with 300 keV energy is around 0.14 mm. In case of 300 eV, the stopping range is shorter than that.
Ok..The deutron beam is of 300Kev whereas the maximum energy of secondary electrons emitted from the surface is around 330ev for which i have to calculate the range!
OK, I got your situation.
The electron range get shorter when the electron energy get lower.
You can check the homepage below.

Then the stopping range of 300-eV electron is much shorter than 10-keV electron (0.5 micro-m in copper).
