<div>Folks,</div>
<div><br>
</div>
<div>I wanted to send out an update on the plans for beam delivery to Hall B for the start of the CLAS12 RG-L/ALERT run. </div>
<div>At the present time the beam restoration work is in progress and things are getting very close in setting up the machine </div>
<div>for beam to all 4 halls. Presently the plan is for shifts in Hall B to begin starting Monday, Mar. 31 with day shift. See the </div>
<div>posted schedule at: <a href="https://www.jlab.org/Hall-B/shifts/">https://www.jlab.org/Hall-B/shifts/</a></div>
<div>There is even a small chance that beam delivery to Hall B could start on Sunday and a standby set of shifts with volunteers </div>
<div>has been setup.</div>
<div><br>
</div>
<div>The plan is to take beam in Hall B at 1-pass energy (2.2 GeV) and begin with establishing the beam tune to the Faraday cup </div>
<div>through the long 45 cm target straw. Then commissioning of the new ALERT detector is scheduled for about a week before </div>
<div>the physics program begins with a pass change to 5-pass energy (10.6 GeV).</div>
<div><br>
</div>
<div>Before arriving for your shifts:</div>
<div>1) Make sure that all of your JLab training is up to date so that you will not have any site access issues.</div>
<div>2) Read the RG-L/Hall B safety paperwork (ESAD, RSAD, COO) posted on the run wikipage at:</div>
<div><a href="https://wiki.jlab.org/clas12-run/index.php/Run_Group_L">https://wiki.jlab.org/clas12-run/index.php/Run_Group_L</a>. When you arrive for your first shift, you are required to sign the safety </div>
<div>binder in the Counting House.</div>
<div>3) I suggest that folks review the ERG document (Emergency Response Guidelines) on the run wikipage to refresh your training.</div>
<div>4) Before your shift begins read the short term shift plans prepared by the Run Coordinator on the run wikipage short-term schedule </div>
<div>at: <a href="https://wiki.jlab.org/clas12-run/index.php/Run_Group_L#tab=Short_Term_Schedule">https://wiki.jlab.org/clas12-run/index.php/Run_Group_L#tab=Short_Term_Schedule</a></div>
<div><br>
</div>
<div>At this point all subsystem Group Leaders should be carrying their on-call phones at all times to respond to calls.</div>
<div><br>
</div>
<div>Let me know if you have any questions. I look forward to working with everyone over the coming months to make this a success</div>
<div>data collection period.</div>
<div><br>
</div>
<div>Regards,</div>
