<html><head><meta http-equiv="Content-Type" content="text/html; charset=us-ascii"></head><body style="word-wrap: break-word; -webkit-nbsp-mode: space; line-break: after-white-space;" class="">Folks,<div class=""><br class=""></div><div class="">We had no beam in the hall overnight and there are a number of remaining issues with</div><div class="">setting up the machine. They have not yet gotten the beam to the Hall D tagger dump</div><div class="">and thus have not yet gone from tuned beam to CW. Overnight they had a variety of</div><div class="">problems with hardware and with machine instabilities. Also they believe that there is</div><div class="">a possible obstruction in the beam path associated with a newly installed cryomodule.</div><div class=""><br class=""></div><div class="">I just met with the Program Deputy. Given the current list of problems in the machine</div><div class="">and the lack of satisfactory progress, the plan today is to send 4th pass CW beam to</div><div class="">Hall C and try to better setup the machine and figure out the source of the instabilities.</div><div class="">After they make progress there, they will then try to tune the 5th pass beam around to</div><div class="">Hall D. Only then will beam be sent to Hall B to begin tuning our line.</div><div class=""><br class=""></div><div class="">Eugene Pasyuk will send out a separate email shortly, but the day shift today is cancelled,</div><div class="">i.e. shifts are cancelled until 4 p.m.. The torus and solenoid magnets are now being</div><div class="">ramped down. Given this development, there is no need to call for a Run Coordinator </div><div class="">meeting today. If there is need to have a meeting tomorrow, I will send out email tomorrow.</div><div class=""><br class=""></div><div class="">As for the hydrogen target, there was quite a bit of progress yesterday and Bob Miller</div><div class="">was able to get the target filled after all system self-checks were successfully completed.</div><div class="">However, the regulation control is not functioning. Dialog with the Saclay folks continues.</div><div class="">I will provide a further update on the target when there is news. Let me know if you have</div><div class="">any questions.</div><div class=""><br class=""></div><div class="">Regards,</div><div class="">Daniel<br class=""><div class="">
