Serious Accident Leads to Accelerator Shutdown

A Special Announcement by Lab Director Jonathan Dorfan

A contractor’s electrician working at SLAC suffered a serious accident on Monday, October 11.  The accident took place in the klystron gallery of the linear accelerator and involved a 480V flashover.  At the time of writing, the electrician is in critical but stable condition. The distress to his wife and family is enormous and I know you all join me in sending our heart-felt prayers for his speedy and complete recovery.

An investigative team, including experts from DOE headquarters and other DOE sites, will arrive on Monday, October, 18 and spend approximately three weeks on-site doing a thorough and in-depth evaluation of the accident. As is appropriate, the scene of the accident is sealed off so as to protect the evidence.

When it Comes to Accelerators, What is Cold?

By Heather Rock Woods

Superconductivity arises in special materials at super cold temperatures. At these temperatures—a few degrees above absolute zero—the materials’ electrical resistance virtually vanishes.

Superconducting technology will be used to accelerate electrons and positrons into extremely energetic collisions in the proposed International Linear Collider (ILC).

This summer, the International Technical Recommendation Panel (ITRP) decided that the international physics community should design the ILC linear accelerators (linacs) with cold technology, rather than the warm technology espoused by SLAC and other institutions.

SLAC and Fermilab to Launch symmetry magazine

By David Harris

SLAC and Fermilab are set to launch symmetry, a new publication for the international particle physics community. The inaugural issue will be released in late October.

This joint publication replaces both SLAC’s Beam Line (last published Spring/Summer 2002) and Fermilab’s Fermi News (last issue in June 2004) with a monthly full-color magazine and accompanying on-line version. This is the first time two DOE national laboratories have combined resources to produce such a publication.
