Reminder: How to Determine JLab Work Status
For updated, recorded messages, call the main telephone number, (757) 269-7100, or call the JLab Status Line, (757) 234-6236. You may also visit the JLab website, where weather closing or delay information will be posted as a banner message.
If timing warrants, your home phone (the number you've listed in the Employee Self Service System) number will receive a pre-recorded message, giving you the latest information about the lab's status. If you have access to your JLab e-mail account, check your inbox for a Site Wide Alert message. If you have a JLab pager, check it for a weather alert/status notice.
In the event of a large or very severe weather event that disrupts electrical power/systems at JLab, knocking out these notification systems, visit JLab's Emergency Site Status webpage. This webpage, which you should bookmark, is only used when all local communication modes are unavailable. For additional information, see the full memo (requires sign in).

The accelerator delivered beam to the experimental halls last week, with some downtime. On Tuesday, beamline vacuum valve 1L12A would not open, and the faulty part was replaced. The north linac 70 Megahertz amplifier dropped the radiofrequency a couple of times. Arc6A power supply was noisy and it was repaired Friday. Hall B nanoamp beam position monitors were unresponsive, and the problem was resolved. The injector was optimized to deliver high current, and Hall C took over 170 microamps of polarized beam for some time. Two shifts were spent for beam studies.
The FEL team had a great week of running and performed the first measurements of photons at 10 electron-volts produced by the FEL’s third harmonic while lasing at 370 nanometers. The group used a hole outcoupler for the harmonics and a calibrated photoemission diode to verify that third-harmonic output is on the order of 0.1 percent of the fundamental, as expected.
Engineering Division Professional Development Program
The first set of eight seminars will be devoted to Cryogenics and presented by the lab's award-winning staff, Jan. 25-April 26. Two overview sessions are open to all lab staff, representatives from local industry and graduate engineering students who have a professional interest in the topic; overview sessions will be held at Jefferson Lab in the CEBAF Center Auditorium. Six technical presentations are for engineers, senior/mid-level technicians and graduate engineering students; technical sessions will be held in CEBAF Center, Room F113. Eight Continuing Education Units will be granted by the Virginia State Licensing Board to professional engineers who complete the cryogenics series. Space is limited and advanced reservations are required for all sessions.

Nearly two-thirds of JLab's past slip and fall mishaps occurred on snow, ice or wet surfaces near entrances or on parking lots. Here are some tips to help you prevent falls:
You can find more information about winter weather precautions for home and travel at Ready Virginia – Winter Weather. In addition, here at JLab, you can report unsafe conditions by calling x7400.
