There are two sheets at this link: RunPeriod-2018-08 (the proposal for this week) and RunPeriod-2018-01 (the data we've collected previously). As a reminder, in Spring 2018 we did not have any high-statistics intensity scan with the final Tungsten foil installed in the beamline.</div><div class=""><br class=""></div><div class="">The proposal covers the same range of intensity (Beam current x RL) as we had in Spring 2018, with 100M events at each setting (aside from the very low intensity, where the rate is too low). As Sergey requested, this also includes a raw mode run at each setting of 1M events, assumed to run at ~3 kHz. The goal is to have a complete set of intensity scan data for efficiency studies with this Fall 2018 data.</div><div class=""><br class=""></div><div class="">The estimated beam time required for this proposal is ~28 hours at 100% efficiency, so it would likely take at least 2 days of calendar time to complete. </div><div class=""><br class=""></div><div class="">Comments/suggestions welcome,</div><div class="">Justin</div></body></html>
