Running Hot

The linear accelerator and SPEAR3 can work through the heat. A number of upgrades and the outstanding work of the maintenance staff have kept the beams operational for the great majority of Northern California's recent heat wave.

"It's only on the very hottest days that it's a problem," said Roger Erickson, who manages accelerator operations at SLAC.

During the peak of the heat wave on July 22 and 23, when temperatures exceeded 100 degrees Fahrenheit, both accelerators struggled as equipment overheated. Dozens of problems appeared for the linac, keeping the beams off until late in the evenings. SPEAR3 avoided losing beam.  Read more...

ILC Reference Design and Detector Concept Reports on Schedule

In closing out last week's Vancouver Linear Collider Workshop 2006, Global Design Effort Director Barry Barish declared that the Reference Design Report (RDR) and Detector Concept Report (DCR) are on track to be released in draft form in early 2007. "We have seen a lot of costing information, and we are still on track," he said.

Hosted jointly by the American Linear Collider Planning Group (ALCPG) and the GDE, nearly 300 participants met for a four-day workshop at the University of British Columbia in Vancouver, Canada. While some meeting participants rose early to take morning swims, the sublime views of the Canadian Rockies and the Pacific Ocean did not distract anyone from the tasks at hand: assess progress made toward writing a RDR and DCR, determine next steps for the ILC R&D program, and complete preliminary costing for the International Linear Collider (ILC).

Prior to this workshop, all Area System Group, Global Group and Technical System Group leaders were given homework: prepare preliminary cost estimates for Barish and the three costing engineers, Wilhelm Bialowons of DESY, Peter Garbincius of Fermilab and Tetsuo Shidara of KEK. "We have three costing engineers—one for each region, and all work was done in concert with the three," Barish said. "Our goal is to come up with the best cost to performance ratio we can, and we have almost complete information. Some pieces are still missing, but we did get pretty much all of the information that we wanted." Read more...

Chemical Storage Map Now Available Online

Today, the Chemical Management System (CMS) group unveils a vital tool: a map of all chemical storage areas at SLAC. Thanks to its creator, the Klystron group's Mary Regan, lab employees can now view all chemical storage areas on site.

The map is available as a word document and can be accessed through the "Chemical Use Maps" link on the chemical information webpage.

The map is especially useful for chemical storage custodians—those individuals responsible for maintaining chemical storage areas at their work site. Chemical storage custodians should view the CMS map to verify that their chemical storage area is represented correctly.

The CMS group needs your help to keep this map up to date. Please contact Judy Fulton, the Hazardous Materials Program Manager, by e-mail if you know of a new storage area that needs to be added to the CMS map or a storage area that no longer exists at a particular building. Please include the following information in your e-mail:

New storage areas
- An attachment of the building's
  floor plan
- Building number
- Location of storage area inside
- Date when an ES&H
  representative can visit site
  to take inventory and photos
  of storage area
- Storage custodian's contact

Removed storage areas
- Building number
- Location of storage area inside
 of building
- Storage custodian's contact

To report general or minor problems, including problems with downloading the file or storage areas placed in the wrong area of the map, directly contact Stafford McCaskill, the CMS map custodian.
