Tor Raubenheimer Becomes Assistant Director
for Accelerator R&D; Division Restructured

Tor Raubenheimer, the head of the International Linear Collider (ILC) group at SLAC, has been named the new Assistant Director for SLAC's Accelerator Research Division. Concurrently, the division has been restructured to include three new departments: ILC , High Luminosity Research and Development (R&D) and Large Hadron Collider (LHC) R&D. A revised organizational chart is now posted online.

"I look forward to working with all involved in this very strong and talented division," said Raubenheimer. "I especially look forward to the sharing of expertise, engineering, and technical resources among the many departments in the new Accelerator Research Division and supporting a broad program that looks toward the future of the laboratory."

The departmental changes to the Accelerator Research Division (ARD) seek to bring together all accelerator R&D associated with the laboratory's Particle Physics and Astrophysics Directorate. This includes the four existing accelerator research departments, SLAC's ILC group, and two new departments. SLAC's LHC R&D group, which had been embedded within the ILC group for historical reasons, is now a separate department of ARD. Likewise, the High Luminosity R&D program on accelerator systems for future high luminosity colliders has become a department of ARD. 

The SLAC ILC group has also become a department under the umbrella of the Accelerator Research Division.  Read more...

Maintaining Our Focus

SLAC's Focus on Safety Week may have happened in July, but the ideas generated in the week's safety meetings and brainstorming sessions carry over to every month of the year. To date, the Environment, Safety and Health (ES&H) division has received meeting reports from over 56 groups, noting over 240 potential injury causation factors and methods of eliminating them.

The vast majority of these issues are self-correcting, as in the case of one respondent from the Photon Science Directorate, who suggested that to avoid foot injuries, an "extra pair of sturdy shoes be kept at work for walking around the site and accessing the accelerator." Or from the Stanford Synchrotron Radiation Laboratory's Accelerator Development and Controls group, which suggested that running to meetings be discouraged.

Regarding office ergonomics, several respondents suggested contacting Medical for an ergonomic evaluation. This is an important function of our Medical Department and is certainly an appropriate way to correct office body mechanics issues before they manifest themselves as injuries. You can schedule an ergonomic evaluation by contacting the Medical Department at x2281.

If the ideas generated in your group meetings involve physical repairs or modification to your workspace, please contact Conventional and Experimental Facilities (CEF) and submit a service request. CEF prioritizes service requests with safety in mind. If you are not sure if your situation fits the definition for a safety request, don't hesitate to contact the CEF Service Desk at x8901 for assistance.

Word of the Week:

Luminosity is the term used to describe the effectiveness of a colliding-beam particle accelerator. It is equal to the number of collisions per second, times the number of electrons in each bunch, times the number of positrons in each bunch, divided by the cross-sectional area of the beams. The tighter the beams are focused and the more particles are packed into each bunch, the higher the luminosity.

In the News:
Fred Kavli Does It Again

Norwegian-born engineer and philanthropist Fred Kavli at his home in Goleta, Calif.

In a ceremony held in Trondheim, Norway, the Kavli Institute for Systems Neuroscience was established last week at the Norwegian University of Science and Technology.

There are now 15 Kavli institutes worldwide dedicated to neuroscience, nanoscience, astrophysics and theoretical physics, including the Kavli Institute for Particle Astrophysics and Cosmology at SLAC.

Safety Seconds

Everyone probably guessed that I was not going to agree with the statement that SLAC's injury rate is as good as one could expect. Amazingly, there are a large number of companies whose total population exceeds six million people whose injury rates are lower than ours. In fact, there are companies with a total of just under one million workers who have an injury rate of one-quarter or less of SLAC's.
