Folks,
<div class=""><br class="">
</div>
<div class="">I support Volker’s suggestions on the two beam energies and the even split of days at each.</div>
<div class="">I also support running with the FT-Off configuration as I do not think that we will have any</div>
<div class="">updated analysis results to tell us anything more than we already know. Also the experiment</div>
<div class="">running before RG-K will be in the FT-Off configuration and this will be most efficienct to</div>
<div class="">stay in this configuration.</div>
<div class=""><br class="">
</div>
<div class="">The other point of consideration is what beam energies we will accept. To be most flexible</div>
<div class="">in getting scheduled, we should be prepared with a statement on what we would accept for</div>
<div class="">running. I would not be so specific, but I do not want different settings all around our request</div>
<div class="">as this really complicates data analysis.</div>
<div class=""><br class="">
</div>
<div class="">We also want to be sure to request that the electron beam is longitudinally polarized with</div>
<div class="">P>80%.</div>
<div class=""><br class="">
</div>
<div class="">Running with the FT-On can be saved for the next part of our beam time after next year.</div>
<div class=""><br class="">
</div>
<div class="">Regards,</div>
<div class="">Daniel</div>

We are planning for t next cycle of runs. There will be opportunity to run RG-K again. I will need to know, ASAP, what beam energy you want to run, 4 pass (~8.5 GeV) or 3-pass (6.4 GeV)?<span class="Apple-converted-space"> </span><br class="">
