comment Velocity distribution in ion source (electron bombardment) for Bainbridge mass spectrometer
Since I saw the bounty get posted, I've tried a few times to see if there was any more information I could find to improve my answer. I can think it can be improved, but I don't know enough about mass spec machines to answer @Julia's questions. It looks like the only way to get those specs is to request them from the manufacturers, and I don't have enough experience with mass spec to know what questions to ask (or even if the manufacturer would know some of the answers).
