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.

The SHMS dipole magnet assembly has progressed to the point that the coil, in its helium vessel, is now surrounded by the cylindrical outer insulation, thermal shield and vacuum vessel. The weight of the coil is now permanently held by the outer vessel rather than by temporary tooling. The full assembly is more than thirteen feet long and five feet in diameter. The inner thermal shield was damaged during insertion, so magnetic-field mapping will proceed while the repairs are made to the shield. In Hall C, the huge iron yoke which will contain the dipole magnet has been leveled and opened. It is now ready and waiting for delivery of the magnet.

Publications Refresher Course Offered Feb. 23
The next Publications Training and Refresher course will be held on Tuesday, Feb. 23, at 9 a.m. in CEBAF Center room F224-225. A brief introduction to the Department of Energy's Public Access Plan and how it affects Jefferson Lab will be presented. In this session, authors will learn how to submit manuscripts to the Publications Review and Approval System, how to make recommended revisions to papers during the signature process, and how to add the relevant information once the paper is published. If you would like to attend, R.S.V.P. to Kim Edwards by Friday, Feb. 19.

Apply Now for the Graduate Fellowship Program at Jefferson Lab
JSA is now accepting applications for the JSA/JLab Graduate Fellowship Program for the 2016-2017 academic year. JSA will award fellowships to qualified doctoral students at SURA member universities for research related to the Thomas Jefferson National Accelerator Facility (Jefferson Lab) in Newport News, Virginia. Each fellowship will provide the awardee's home institution with a $10,000 stipend. The awardee's home institution must agree to provide the remaining research assistant stipend from institutional or research funds. An additional $2,000 supplemental stipend is provided to the awardee's home institution for the graduate student. Conference travel support is also available for use during the fellowship period. The JSA/JLab Graduate Fellowship Program is funded by the JSA Initiatives Fund. Funds for the 2016-2017 Graduate Fellowship Program are limited. Application materials are due by February 29, 2016. Visit the website for an application form and application requirements. If you have any questions about the program, contact Elizabeth L. Lawson at

JSA Offers Sabbatical and Research Leave Support at Jefferson Lab
JSA is now accepting applications for the JSA/JLab Sabbatical and Research Leave Support Program for the 2016-2017 academic year, with support beginning as early as summer 2016. The JSA/JLab Sabbatical and Research Leave Support Program enhances research opportunities for faculty through access to Jefferson Lab facilities and interaction with Lab researchers and users, strengthens the teaching and research capabilities of universities through faculty involvement, and strengthens the research programs of the Lab by attracting “new blood” and integrating university faculty members in the Lab's programs. The program is funded by the JSA Initiatives Fund. Application materials for the program are due by March 31, 2016. Visit the website for an application form and proposal requirements. If you have any questions about the program, contact Elizabeth L. Lawson at

The Installation group has been busy the last few weeks. Some of the highlights are:
  • Finished installing the Hall C beamline cantilevered stand and bridge, which supports three BE (bending) magnets, an unser girder and raster and detector stands;
  • Installed and connected the cooling water system for the above components;
  • Hall C's dump weir and rails were demolished to allow the installation of a new designed dump (similar to Hall A's);
  • In the injector test cave, the SSG box duct and cable tray were installed;
  • In the accelerator, box supplies were acid flushed, VIP repairs were made, DP station was pumped down and some valve position switches were replaced;
  • During the winter down, more box supply acid flushing was carried out, low-conductivity water leak repairs were made and many VIPs were troubleshot and repaired;
  • 30 valve position switches were upgraded to all-metal switches; and
  • Hot Checkout of both the LCW and vacuum systems were completed.

Environment, Health, Safety and Quality

Get Jefferson Lab Emergency Contact Card
All members of the Jefferson Lab community are encouraged to carry their Jefferson Lab emergency notification and reminder card with their lab ID. The card lists the primary numbers for reporting emergencies, injuries, or any abnormal situation, as well as guidance on reporting emergencies and other situations and staying safe. The cards are available at the reception desks in the Support Service Center, Bldg. 28, and CEBAF Center.

Computing and Networking Infrastructure

Scientific Computer Filesystem Data Issue
Due to a hardware failure over the weekend, a small subset of files on the scientific computing Lustre system was lost. This affects files in /work, /cache, and /volatile. If your data is affected, file access attempts will return the error "Cannot send after transport endpoint shutdown." The scientific computing group is working on automatically removing the affected files. Computer system users who see this message in the meantime should remove the files with the "unlink" command, after which each file can be manually recreated. The Scientific Computing group is working with the vendor on a long term stability fix for the affected file servers. If you have any questions or concerns about this issue, contact the IT Division Helpdesk at x7155 or
