    12 GeV Upgrade
    In Hall B, the magnet support legs were installed and the bases grouted on the Torus magnet. The plan is for the “spit,” which has served as the temporary support for the magnet during the coil installation phase, to be removed later this week. 

  • You will recall that in the fall of 2015, I wrote a Montage about the intent to develop an Integrated Diversity and Inclusion program. The Diversity and Inclusion Council, under Chairpersons Mary Logue and Rolf Ent, has been working in collaboration with the Public Affairs office on several initiatives, which will soon go public. One of the very interesting but pernicious effects which, to a greater or lesser degree, we all are susceptible to is implicit bias. We are also looking to provide training for supervisors and also to enhance the information provided to people involved in the hiring process, which would include cultural context, gender communications, as well as implicit bias.

    12 GeV Upgrade
    Power-testing of the Super High Momentum Spectrometer Horizontal Bend (HB) magnet has resumed after engineers implemented further modifications to improve the response time of the power supply's quench-detection circuitry. When this magnet reaches the current required for 11 GeV/c operation, its magnetic field will be mapped, and the magnet construction contract with Michigan State University will be complete.

  • Our upgrade project is called the 12 GeV CEBAF Upgrade Project.

    At the time CD-4A was achieved, we demonstrated 2.2 GeV per pass. This was 12 GeV! Well, not quite. In fact with more than one pass, we limited ourselves to a little more than 6 GeV with three passes, and to 10.5 GeV with 5.5 passes. It was not felt to be prudent to demand 12 GeV out of the machine immediately after turn on.

    12 GeV Upgrade

    Last week was very productive for the 12 GeV Upgrade project, with major achievements realized in both Halls B and C. In Hall B, the energization of the Torus magnet achieved full current of 3,770 Amps on Friday afternoon, Nov. 4. Mapping of the magnet field then commenced, and, once complete, the Torus will be powered down and installation of the remaining detectors will restart.
