Dear Marco,
<div class=""><br class="">
</div>
<div class="">those are exciting news - things going in the right direction for a change! Let’s see if it pans out this way - the RTPC is ready. </div>
<div class=""><br class="">
</div>
<div class="">Here is a short list of things that will need to be taken care of so we are in optimum shape:</div>
<div class="">
<div>- Target gas bottles with H2, 4He, and D2 (the latter must be a NEW bottle) on the gas pad.</div>
<div>- 4 He/CO2 drift gas bottles multiplexed together on the gas pad</div>
<div>- All pressure transducers and MFCs operational </div>
<div>- Update clas12mon and CED in the CH to the most recent version (with David Payette’s updated RTPC monitoring plots and Gagik’s fix of the overflow problem).</div>
<div><br class="">
</div>
<div>1000 thanks to everyone for getting us ready in time!</div>
<div>- Sebastian</div>

Dear all,
<div class="">this is what I received from Jay few minutes ago. It seems we have some hope to receive beam into the Hall by the end of the week!</div>
<div class="">We can discuss it tomorrow at the 2:30 meeting and decide whether we need to resume shifts over the week end.</div>
<div class="">Who’s is going to be the RC in the upcoming week?</div>
<div class="">Cheers</div>
<div class="">Marco<br class="">

<div class="">I don't know who the on-coming RCs are so I address this to the usual suspects. Please forward. I am on-coming PD. Beam is presently in arc 6 with good arc 5 match. My optimistic estimate:<br class="">
<br class="">
End of Tuesday day shift: finishing 6E match<br class="">
End of Tuesday swing: finishing 7E<br class="">
<br class="">
End of Wednesday swing: knocking on 5C00<br class="">
End of Thursday owl: matched at 5C00<br class="">
Thursday day shift: maintenance<br class="">
Thursday swing: recovery to 5C00 after maintenance<br class="">
Friday owl: match first pass to Hall A dumplet* allsave<br class="">
Friday day: match first pass to Hall B dumplet*<br class="">
Friday swing: propagate beam to 3C dumplet<br class="">
Saturday owl: poke beam into Hall B<br class="">
Saturday day: poke beam into Hall C<br class="">
Saturday swing: photons to Hall D<br class="">
<br class="">
So lock up Halls B,C,D Friday afternoon. But enough sweepers might not be found Friday. C is ready to lock up and so could be swept Thursday swing and taken to controlled. Or even Wednesday swing. B or D Thursday swing and the other Friday swing? Would
any of you object to Wednesday swing lockup of C, Thursday of D and Friday of B? Controlled access to C and D until Friday swing.<br class="">
<br class="">
* Hall B gets four days at first pass before beam goes back to CREX. Hall C also needs two days at first pass but this hasn't been scheduled AFAIK<br class="">
<br class="">
If all goes well, switch B back to fifth pass early Wednesday August 5 and start beam to A. Getting back to 150 uA first pass will be interesting so I'd like it to start soon after the 8am meeting.<br class="">
<br class="">
Depending on where we are 1330 Wednesday, 0745 meetings will start either Thursday or Friday of this week.<br class="">
<br class="">
Jay<br class="">
