<p class="MsoNormal">Hi Mark, <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">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.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">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.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Please put all your spreadsheets on the sharepoint site.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Call if you have questions.<o:p></o:p></p>
