[Sneap] NEC pelletron C stripper foil question

[Lucas Phinney]

Hello,

I am a graduate student at the University of North Texas working in the Ion
Beam Modification and Analysis Laboratory (IBMAL) with Dr. Jerry Duggan.  I
am trying to get higher charge states of a C beam (+5 and +6), with a 3 MV
NEC 9SDH-2 Pelletron.  We are currently using the Nitrogen gas stripper and
I can only get up to +4 charge state, and I was hoping that by going to the
solid foil I would be able to get the higher charge state.  I was wondering
if anyone had experience using C foil strippers in the tandem and could give
me some pointers.  I was specifically wondering what thickness would be
best, but any information would be appreciated.

Thanks
