Celebrating Jonathan, Colleagues and Collaborations

by Shawne Workman

During a July 24 celebration of SLAC Director Emeritus Jonathan Dorfan's 32-year SLAC career, physics leaders from around the globe reviewed the accomplishments of decades of successful collaborations—from the days of Mark I and Mark II detectors through the evolution of SLAC into a leading photon science, particle physics and astrophysics laboratory. A symposium in Panofsky Auditorium was followed by cake, ice cream and reminiscences on the SLAC Green and a dinner "roast."

Morning introductions included letters of congratulations from well-wishers who could not attend, among them U.S. Representative Mike Honda, current SLAC Director Persis Drell and DOE Associate Director for Science for High Energy Physics Dennis Kovar. Posters celebrating such milestones as the Mark II detector, PEP-II collider, Kavli Institute for Particle Astrophysics and Cosmology and the Linac Coherent Light Source heralded the day's stories.

Physics from BaBar at ICHEP08

by Abolhassan Jawahery

The major summer conference for particle physics, the 2008 International Conference on High Energy Physics, or ICHEP08, is currently underway in Philadelphia. There, hundreds of researchers from laboratories and universities around the world are spending this week and next discussing the most exciting high-energy physics results of the past year.

As in the past, the BaBar collaboration will have a great harvest of physics to present at the conference, including the first results from our final run.

Word of the Week:
Antiparticle

by Brad Plummer

In particle physics, antiparticles are the subatomic counterparts of most kinds of particles, having the same mass but opposite charge (among other variables). The positron, for example, is the antiparticle partner of the electron, having a positive charge. Protons similarly associate with antiprotons.

Antiparticles are produced naturally in certain types of radioactive decays, and were first observed in the early 1930s. Scientists first succeeded in assembling antiparticles into antiatoms in the mid 1990s by combining positrons and antiprotons to form antihydrogen.

Building the LCLS: Weekly Update

by Brad Plummer

Construction highlights for the Linac Coherent Light Source (LCLS) this week include:

• Preparation for energizing the water handling systems in the Beam Transport Hall and Undulator Hall and throughout the facility.

• Installation of sprinklers and ductwork in the Far Experimental Hall.

• Electrical grounding installation in the Access Tunnel leading to the FEH.

New Facilities Request System: FAMIS

by Gail Fong

A new facilities request system goes into effect today, as part of a larger system called FAMIS (Facilities Asset Management Information System) that will allow the Facilities Department to better manage work requests, equipment, preventive maintenance and costs.

Access the new system through the Facilities Web site to enter facilities-related safety, work and Fleet Services requests, and to look up request status. Please direct questions to the Facilities Service Desk (x8901).

Safety Review: Feedback and Improvement

by Steven Frey

This is the final article in a five-part series examining each of the five core functions of SLAC's Integrated Safety Management System. The core functions are hands-on tools to help you plan and conduct work in a safe manner. Their relationships are depicted in this handy diagram:

The fifth ISMS core function introduces quality control into the work planning process. Following this function, you apply experiences and lessons from earlier jobs to enhance work planning and further minimize risk of accident, illness or injury. The central question is, "How can I do better next time?"

Consider the example job, welding a girder. After the work has been scoped, planned and implemented within the planned safety controls, a review of the job can provide invaluable information to keep future work safe. A welder might learn from a co-worker that leaning toward the girder inadvertently brought him or her close to a slip or fall, or near to a previously unknown electrical or radiation hazard. Individuals may be aware of different "minor" situations that, when reviewed collectively, reveal a larger risk.
