12 GeV Upgrade
Design effort on the conventional facilities to support the 12 GeV
CEBAF Upgrade continues to progress. On Dec. 20, the Design and Safety
Review meeting on the 100 percent design of the North and South Access
Building Additions was held at Jefferson Lab. Facilities Management and
Logistics is focused on completing the 100 percent designs for the Beam
Switchyard (BSY) Addition and the North and South Access Utility
Upgrades this month. On Feb. 1, the Architect-Engineer (A-E) firm, HSMM
(Hayes, Seay, Mattern & Mattern), is scheduled to submit the draft
Final Design documents of the Hall D Complex for JLab review.
Physics
In Hall A, the Coulomb Sum Rule experiment E05-110 is
presently running (Jan. 14) the penultimate of the 17 energies
scheduled for this experiment; it's on track to have accumulated all
the
required data by Wednesday, Jan. 16.
In Hall C, GEp-2γ (E04-019) has
completed data
taking on two of three kinematic data points. The remaining data taking
on the partially completed third point is scheduled to resume later
this week.
Accelerator
The accelerator ran exceedingly well during this period, with a
realignment of a section of beam pipe in the North Linac the only
corrective action necessary. Up to Jan. 11, the three experimental
halls
received 162 hours of beam. After a change to the very low energy
of 400 MEV ½ pass on Jan. 11, only Hall A was taking beam and to
date (Jan. 15), Hall A has received 50 hours of beam at the new energy.
Free-Electron Laser (FEL)
This week, FEL staff completed a major milestone in
certifying
the gun test stand and the FEL for independent operation. The GTS gun
high-voltage conditioning was then begun by ramping and soaking
immediately at
330 kilovolts. At the same time, the FEL gun and adjacent
beamline bake was completed. FEL staff are continuing to process the
GTS high voltage
on 24-hour shifts.

Adopt-A-Spot Litter Pickup event on Jan. 25
The 12 GeV Upgrade project team, along with ESH&Q staff, seeks
volunteers to help with litter pickup along the sidewalk & grass
areas from Onnes Drive to the corner of Jefferson Avenue & Oyster
Point Road. Participants will meet in the CEBAF Center lobby at 11:15
a.m. for a short safety briefing and will then proceed to pick up
litter. If you would like to participate, contact Cindy Saban at x5981
or saban@jlab.org in advance.

Environment, Safety, Health & Quality
Lab staff members
recently expressed concern about the number of deer sighted around the
JLab campus. The following are basic safety tips for driving near deer
from the Insurance Information Institute:
- Be especially attentive from sunset to midnight and
during the hours shortly before and after sunrise. These are the
highest risk times for deer-vehicle collisions.
- Deer seldom run alone. If you see one deer, others
may be nearby.
- When driving at night, use high beam headlights when
there is no oncoming traffic. The high beams will better illuminate the
eyes of deer on or near the roadway.
- Slow down and blow your horn with one long blast to
frighten the deer away.
- Always wear your seat belt. Most people injured in
car/deer crashes were not wearing a seat belt.
- If your vehicle strikes a deer, do not touch the
animal. A frightened and wounded deer can hurt you or further injure
itself.
PNNL Electrical LO/TO
Lesson Learned
A Pacific Northwest National Lab electrician, while removing two
120-volt power supply cables from a bundle of four de-energized
120-volt power supply cables, recently removed another authorized
worker's Danger Tag. There was no lock, but the Danger Tag had been
attached. The worker did not contact any hazardous energy source. The
work activity was stopped, and the electrician's lock and tag
qualifications were suspended. An event investigation was formed by
line management to conduct a review, including causal analysis. This
event, although a "near miss," points out the importance of workers
being aware of and following energy control measures: All JLab staff
working near any type of energy control devices on systems such as
electrical, hydraulic, fluid, or cryogenic need to aware of the
importance of complying with Lab lockout/tagout/try measures. For more
information, see Chapter 6110 Lock, Tag, Try in the Lab ES&H Manual.
Computing and Networking Infrastructure
Automatic Installation of Microsoft Office
On the evening of Feb. 5, the Computer Center will
automatically install Office 2007 on all JLab Common User Environment
(Computer Center-managed) Windows systems that haven’t already
installed it. *Non-Windows systems, including Unix-based systems such
as Mac OS X and Linux, will not be affected.* To sign up for training
in the new features of Office 2007, see the announcement.
As always, should you encounter difficulties with your computer, call
or visit the Computer Center Help Desk, x7155 or CEBAF Center F200.
E-Mail changes to impact users of Pine, Mutt and
mailx clients
Changes are being made to JLab's e-mail environment to improve e-mail
performance and manageability. The first phase of changes will be
implemented on Feb. 5 and will directly affect those who use text-based
e-mail clients on Unix systems. Examples include Pine, Mutt and mailx.
These changes will likely not affect those who use Thunderbird,
Outlook, Mozilla or other e-mail clients that use the IMAP protocol to
read mail.
The changes that will take place are two-fold:
- The mail spool directory (/var/mail) is currently
mounted on all
central user login machines, as well as many CUE level 1 linux desktops
around the site. This access is being removed. This means that users of
Pine, Mutt, or other text-based e-mail readers in Unix systems will
need to configure these e-mail readers to use IMAP to access e-mail.
Access to e-mail on the local file systems will no longer be permitted.
- Some advanced users have their inboxes stored in
their home directories
in a file called mbox. These users will have their inboxes migrated
back to the mail spool directory. This change will be transparent to
all users that use IMAP e-mail clients.
Additional changes that will affect all users and where you store your
e-mail folders will take place later in the spring/summer.
Announcements will be made regarding those changes at a later date.
Scientific Computing Users Meeting on Jan. 23
Scheduled for 9:30 a.m. in L102, this meeting
will provide users
with an open forum to discuss JLab's offline experimental physics
scientific computing environment. Planning for batch farm computing and
storage for the next several years are the primary agenda items. A
detailed agenda can be found on the Events
Calendar.
