Subject: RE:SIMION gem file - update
Hi everybody,
attached are updated copies of the simion GEM files that I am using for our IMS simulations.
In the previous GEM files, the ring electrodes were offset from the rest of the TOF section by 5mm.
(due to typo in prog I use to create the files !)

This has now been corrected.

As before there are two version, IMS_CF ions pass through Carbon Foil, and IMS_OP - opaque ions are stopped at the foil.
