Dear Annalisa,
<div><br>
</div>
<div>Thank you for the email confirming that RG-K is ready to run in FY27.</div>
<div>
<p data-start="173" data-end="515">I am not sure where the information came from that Møller will start running in the second half of the beam period. There is no official schedule yet, and at the Møller ERR in August it was indicated that the Møller KPP would
take place in January 2027. This would require that the injector be configured for Møller polarization at that time.</p>
<p data-start="517" data-end="659">I will keep your request to run first in mind, but I want to retain flexibility, as the detailed schedule may require a different arrangement.</p>
</div>
<div>Regards,</div>

<p style="font-family: ComicSansMS;">Dear Stepan,</p>
<p style="font-family: ComicSansMS;"><span style="caret-color: rgb(255, 38, 0);">W</span>e have discussed your proposal within the RG-K group and we all think it would be great to take data for RG-K in <span style="font-size: medium;">FY27. We are ready to
increase and eventually complete our assigned PAC days.</span></p>
<p style="font-family: ComicSansMS;"><span style="font-size: medium;">We have also learned that in FY27 Hall A is expected to run the MOLLER experiment (possibly starting in the second half of the beam period), which requires very high beam polarization with
high-rate polarization change. This may have an impact on the magnitude of the polarization possible in Hall B (and, possibly, on the correct reconstruction of the beam polarization in our DAQ).</span></p>
<p style="font-family: ComicSansMS;"><span style="font-size: medium;">Since we understand that RG-E is not sensitive to the beam polarization, it would beneficial for us to run in the first half of the beam before before MOLLER so we can ensure that we maximize
the RG-K beam polarization.</span></p>
<p style="font-family: ComicSansMS;"><span style="font-size: medium;">Thank you for this opportunity</span></p>
<p style="font-family: ComicSansMS;"><span style="font-size: medium;">All the best</span></p>
<p style="font-family: ComicSansMS;"><span style="font-size: medium;">Annalisa</span></p>

<div><span style="font-size: medium;">I’m putting together a tentative run schedule for after the FY26 PRad run. One likely scenario for FY27 is running RG-E and RG-K. I’d like to get the run groups’ views on whether you are ready and willing to proceed, or
if you would prefer additional time to analyze the existing data before the next run. If you can get back to me before next Tuesday, that would be great.</span></div>
