[Tgun] Moving forward

[Fay Hannon]

Hi Mark,

For now, I'd suggest moving forward with measurements despite the FE beam. It seems small @ 90kV, so let's ignore it for the next stage of measurement.

I would like to focus on the I-V curve, so we need to get beam to the dump to measure the current. You might even be able to measure the FE current first (for different sol settings). I think though, that for the 'transconductance' measurement we can do this with modulated beam - you know Uc now, and have calibrated Urf - so you should be able to calculate the g21 from the equation of average current predicted. I think you would want to do this at a variety of HV settings.

Please put all your spreadsheets on the sharepoint site.

Call if you have questions.
Fay
