BaBar Data Archive Prototype Arrives

In preparation for long-term access of its eight-year data set, the BaBar Collaboration acquired four prototype computers at SLAC this month. The machines are now undergoing testing by BaBar computing specialists and the SLAC computing team. A total of sixty machines, containing one petabyte of data from the BaBar experiment, will eventually reside in the SLAC computing building. The Long Term Data Access project, or LTDA, will ensure that data is reliably available and easily accessible through 2018.

Director's Work Group Meetings
December 6–8

I will be holding work group meetings December 6-8 in the Kavli Auditorium. These sessions will provide you the opportunity to speak face-to-face with me about anything on your mind. There will be six meetings organized by directorate using the below schedule, with an 8 a.m. combined Owl Shift and Accelerator Directorate meeting on Tuesday, and an overflow/open meeting Wednesday for anyone unable to attend their dedicated directorate session. The Operations Directorate has asked me to address them on December 9 at another venue, so the six sessions listed below do not include Operations.

Schedule by directorate:

  • PPA: Monday, Dec. 6, 2–3 p.m.
  • AD with last names A–M and Owl Shift: Tuesday, Dec. 7, 8–9 a.m.
  • SSRL: Tuesday, Dec. 7, 9:15-10:15 a.m.
  • LCLS and Photon Science: Tuesday, Dec. 7, 2:30–3:30 p.m.
  • AD with last names N–Z: Wednesday, Dec. 8, 2:45–3:45 p.m.
  • Overflow/Open: Wednesday, Dec. 8, 4–5 p.m.

Colloquium Monday: Dark Matter

Next Monday, December 6, astrophysicists Simona Murgia, Louie Strigari and Risa Wechsler of the Kavli Institute for Particle Astrophysics and Cosmology will present a special SLAC colloquium celebrating the international event Dark Matter Awareness Week. SLAC is in the forefront of institutions using a number of varied approaches to seek answers to the mystery of dark matter, the elusive substance that is thought to make up more than 20 percent of the universe. In Monday's colloquium, each speaker will present a 15-minute talk covering a different aspect of research into dark matter.

The colloquium will begin at 4:15 p.m. in Panofsky Auditorium. It is free and open to all. 

Please Don't Cross the Tape!

With construction happening near Buildings 50, 28, the Visitor Parking lot and more, please stay alert to changing conditions and especially safety barriers along your regular walking routes. It may seem simple to duck under a ribbon of "caution" tape, but please, don't! It's there for a reason, and you don't want to accidentally walk into a construction trench or piece of heavy equipment. Unless you are wearing the correct personal protective equipment, and are authorized by the field construction manager, you may not pass a designated construction area barrier. Please stay outside the fences and don't cross the tape.
