12 GeV UpgradeThe Torus magnet for CLAS12 has been parked at a temperature of 80 Kelvin for the past two months awaiting the upcoming beam run in Hall B. t will be brought back down to liquid helium temperature at the end of January to prepare for the run. The drift chambers have all been suspended from the Torus cryostat and had their services attached, and the Forward Carriage has been rolled upstream to its operating position next to the Torus.
The five coils of the Solenoid magnet have now been spliced into one continuous circuit, and the resulting magnet “cold mass” has been covered with reflecting aluminum foil. The radiation shields are now being fit to the outer circumference of this assembly. After this step, the multi-layer insulation blankets will be added and then the entire assembly will be suspended inside the cryostat outer shell; eight suspension links are welded to the cryostat and then attached to the cold mass by insulating links in this step. The conical end regions and the bore tubes of both the radiation screen and the cryostat were prepared earlier and will be attached after the cold mass is suspended from the cryostat outer shell in order to close the cryostat. Planning for shipping the Solenoid to Jefferson Lab is well underway, including the final steps in the design of the shipping cradle and isolation springs needed for the road trip to Virginia.
PhysicsL’Oréal-UNESCO For Women in Science Program Applications Due Feb. 3
The L’Oréal-UNESCO For Women in Science program recognizes and rewards the contributions women make in STEM fields and identifies exceptional women researchers committed to serving as role models for younger generations. More than 2,250 women scientists in over 110 countries have been recognized since the program began in 1998. In the U.S., the program awards five postdoctoral women scientists annually with grants of $60,000 each. Applicants are selected from a variety of fields, including the life and physical/material sciences, technology (including computer science), engineering and mathematics. Applications for the program are now open and are due on Friday, Feb. 3. The application and more information can be found at the link.
Nominate A Colleague for the 2017 Outstanding Nuclear Physicist Award
JSA is now accepting nominations for the 2017 Outstanding Nuclear Physicist Award, which recognizes individuals who have made outstanding and sustained contributions, including technical achievements, to experimental and/or theoretical research related to the nuclear physics program at Jefferson Lab. The biennial award consists of a certificate and a $10,000 honorarium, presented to the honoree at the Jefferson Lab Annual Users Group meeting. Deadline for submissions is Jan. 31, 2017. See details and poster online.
Center for Theoretical and Computational PhysicsA new paper shows how a thorough amplitude analysis of the data available for the Zc(3900) peak, seen by BESIII and Belle, can help with constraining phenomenological models. It discusses possible scenarios of a QCD state, a virtual state, or a kinematical enhancement. Although the current data are not precise enough to distinguish between these hypotheses, the proposed method may shed light on the nature of these exotic enhancements when applied to data from forthcoming high-statistics measurements.
