LCLS on a Pedestal

Last week, a team working with the Linac Coherent Light Source (LCLS) construction project repositioned dozens of undulator magnets to make room for pre-assembly of the undulator support pedestals. For months, the undulators have remained stored in wooden crates in the Collider Hall, and now the first stages leading to their installation next year are set to begin.

"The most exciting thing for me is just seeing it all start to come together," said Ben Poling, leader of the group that will pre-assemble the undulator support systems. "I've been with this project since the beginning. It's really satisfying."

Poling and colleagues are currently making room among the rows of crates for the coming parade of related equipment—vacuum chambers, quadrupole magnets and beam position monitors that the team will soon start piecing together. Assembling these structures calls for a dedicated workspace furnished with high-precision mock-ups—actual replicas of the final support stands—for aligning the components, which Poling's group is currently setting up in the Collider Hall. The undulators will only be installed once the pedestals are in place in the Undulator Hall. In all, the LCLS will use 33 undulators at one time, with seven serving as back-ups.

ILC Physicists Build Their Dream House

Older detectors can still teach us new tricks; IRENG07 participants inspected the rollers of the SLAC Large Detector.

Be it a house renovation or even a proposed particle accelerator, anyone involved in a construction project can appreciate the 1948 classic film Mr. Blandings Builds His Dream House, starring Cary Grant and Myrna Loy. In a memorable scene, the married couple meets with their architect, who presents them with the plans for their home. Mr. and Mrs. Blandings proceed to mark up the plans until they are no longer recognizable, turning the mere home into their dream home. Sure, there is the minor detail of the chimney going through the middle of Mrs. Blanding's sewing room, but that is the architect's problem to figure out, right?

As opposed to the Mr. and Mrs. Blandings method of taking the design of their dream house into their own hands, the ILC engineers, accelerator and detector physicists are already engaging in a dialogue (hopefully one that will prevent a chimney going through the middle of a detector). Roughly one hundred members from the ILC engineering, accelerator and detector communities started swapping information at the IRENG07 workshop that took place at SLAC in mid-September.

Even though the proposed construction start for the ILC is still years away, a detailed schematic for the underground detector cavern should be prepared now, as part of the engineering design phase for the project. The engineers need to know such things as the detector dimensions and the weight of the heaviest components to determine how many and what types of cranes will be needed. The detector concept groups need to provide the answers, which isn't exactly easy as they are still defining their engineering designs too. The accelerator physicists need to make sure that the design of the hall and the detectors won't have impacts on delivering the highest quality beam. All the different requirements can be overwhelming for any person involved in the project, but the participants at IRENG07 have the comfort of knowing that they are all ultimately working toward the same goal—scientific discoveries.

Black Box Opens Its Doors This Friday

This Friday, you can step inside the shipping container that has boosted SLAC's computing power by a third in recent weeks.

The Sun Microsystems Project Blackbox—an 8 by 20-foot shipping container painted white—houses 252 computing systems.

The box will be open from noon to 3:00 p.m. on Friday, October 19, allowing the curious to walk through the center aisle of the mostly self-contained computer center.

A Sun engineer will answer questions about Project Blackbox at SLAC, the first installation to be tested by a customer.

Scientific Computing and Computing Services staff will be on hand, also offering tours of the machine room on the first floor of the Computing Building (Building 50).

The box is located behind the Computing Building. You can walk around the building to the back, or go inside to the Help Desk, where staff will direct you to Project Blackbox.

For more information, contact Chuck Boeheim.


Embroidered Logowear Now Available Online

(Photo - Kurt Vaillancourt in Lands End jacket)SLAC and Linac Coherent Light Source (LCLS) logowear is now available directly from Lands' End Business Outfitters. A website set up specifically for SLAC's "Friends of the Linear Accelerator"—which facilitates the logowear sales—allows SLAC employees, contractors, users and fans to order SLAC gear online.

Hundreds of catalog items, embroidered with either the SLAC or LCLS logo, are available at this website year-round. There is no minimum order quantity.

This web capability has eliminated the need for the special logowear sales that were previously held at SLAC each November.

Additionally, many in-stock logo items are available in the Stanford Guest House gift shop. The gift shop is open 7 days a week, 24 hours a day, in the Guest House lobby.
