<div class="logentry node-content">
<p>We have made significant progress today. Our detectors and spectrometers are all running smoothly and ready to take electrons from targets. We are officially in the Tritium-mode Phase-I (meaning gas-target locked, solid-targets only, max. 10uA with raster on/off).<br />
The accelerator is able to send us some 5th pass tune beam and even some CW beam into the hall, despite some issues with the harps near the target region which MCC is trying to fix. </p>
<p>Plan for tonight and tomorrow --- Once we have good CW beam, we will immediately start the ion-chamber calibration, beam-centering, bull's eyes scan, and detector/DAQ checkout. These will hopefully be finished during the following Swing/Owl shifts. If we can finish these tasks by tomorrow early morning, we will put the sieve slit plates in on both arm and then start the optics run. All shift-workers will be needed to be on shifts from now on. </p>
<p>We still have lots of empty spots in this weekend and next week that we really need your helps to fill in. We will have one more TO training tomorrow (please contact JP) and more if needed next week.Doug will find a good time next week to help new shift-workers to complete the Hall safety walk-through so please contact with him to work out the best time for you.</p>
