<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="">Yesterday during the day the machine was down for a period of beam studies. The plan </div><div class="">was to begin restoration at the start of swing shift and continue setting up the machine</div><div class="">and the tuning of 5th pass beam to Hall B. However, a number of hardware problems </div><div class="">including a dipole power supply failure in our line did not allow any beam to be delivered </div><div class="">to Hall B last night. At 7 a.m. today the machine went down for RF recovery with the plan </div><div class="">to begin restoration of beam by the start of swing shift. </div><div class=""><br class=""></div><div class="">Today in the hall there will be work on the problematic Hall B cryo-target and I hope to have </div><div class="">some news on developments before the day is done. Bob Miller is presently in the hall going</div><div class="">through a series of detailed investigations/checks based on communication from the Saclay </div><div class="">expert that was received this morning. Also the magnet group will be in the hall trying to better </div><div class="">understand the source of the fast rampdown of the solenoid yesterday due to noise in the </div><div class="">quench detection circuitry.</div><div class=""><br class=""></div><div class="">Given the current status, there will be no Run Coordinator meeting this afternoon. I will sent </div><div class="">out email tomorrow with a status update and plans for our next meeting. If you have any </div><div class="">questions, let me know.</div><div class=""><br class=""></div><div class="">Regards,</div><div class="">Daniel<br class=""><div class=""></div></div><div class=""></div><div class=""></div><div class="">
