Come Celebrate the LCLS

I invite all SLAC staff and users to join me in celebrating the Linac Coherent Light Source Dedication on Monday, August 16. We will gather on the main SLAC Green at 2:15 p.m. to officially dedicate this incredible facility. I will be joined by U.S. Secretary of Energy Steven Chu, Stanford President John Hennessy and others in highlighting the accomplishment of the LCLS and the innovative science that is already providing new insights into the atomic world. The short ceremony will be followed by entertainment and a reception on the Green.

I ask that supervisors please make arrangements to ensure everyone can attend; it is important that we take time to celebrate this truly SLAC-wide accomplishment.

I look forward to seeing you there.

SAFE2010: SLACers Join Forces to Reduce Risks and Re-use Materials

The age-old maxim that there is strength in numbers rings true when it comes to safety at SLAC National Accelerator Laboratory. Several departments, including Waste Management, Facilities and Environmental Safety and Health, worked together to remove two modules containing tubes of ethane gas from a site near Interaction Region 6, where they had sat untouched for several years. In addition to creating a safer environment for SLAC employees, the groups found a way to reuse the material that resulted in a cost savings for the lab.

A now-retired SLAC engineer ordered the ethane for use in the Stanford Large Detector experiment on the former SLAC Linear Collider. When the research came to a close in 2001, the spare ethane tubes were left at the site to await a new home. The two trailers—each containing 38 tubes of the highly flammable ethane gas—were moved from site 750 to site B666 to make way for the construction of the Linac Coherent Light Source in the fall of 2006.

The question of finding them a permanent home landed in the lap of Waste Management section leader Yolanda Pilastro in July 2009.

"I knew this project would be a challenge," she said.

Pilastro immediately began searching for ways to reuse the gas, either at SLAC, another Department of Energy site or a commercial vendor. After extensive networking, she located Airgas, a Pennsylvania-based distributor that was willing to take the ethane tubes and transport them to their Houston, Texas facility to be reused.
