People: Ian Evans Champions User Safety

He's back! Environment, Safety & Health Program Manager Ian Evans has returned to SLAC after three years developing the user safety program at the Spallation Neutron Science and High Flux Isotope Reactor research facility at Oak Ridge National Laboratory in Tennessee. Prior to working at Oak Ridge, Evans managed the ES&H program at the Stanford Synchrotron Radiation Lightsource for 16 years. His duties at his new position will include continuing to develop a user safety program at the Linac Coherent Light Source, updating SSRL's user program, and integrating the two.

"SSRL is an established, mature facility, whereas LCLS is young and in the process of developing a program from a user's standpoint," Evans said. "The end goal is that, from the user perspective, the systems you see would be equitable at SSRL and LCLS."

To help SLAC offer world-class user programs in addition to world-class facilities, Evans will work to combine safety and operations programs so that users will see congruency between the two user facilities. Users will see consistency between SSRL and LCLS programs during the proposal review process, throughout a unified training program, and when interacting with support staff who will have similar roles and responsibilities at each facility. These commonalities will enable smoother transition for users who may have worked at SSRL in the past and are starting experiments at LCLS.  Read more...

WIS Seminar Today:
Helen Quinn on Science

Don't forget to bring your lunch to Panofsky Auditorium today at noon to hear esteemed theoretical physicist Helen Quinn discussing "What is Science?"

Quinn will use her 40+ years of experience in physics, science education and outreach to address what might seem like a basic question. Quinn has found that the general public and scientists don't always share a common understanding of science—how it is conducted, how progress comes about, and what its inherent values and limitations are. Some of her insights may surprise you.

A former American Physical Society President and winner of the Dirac Medal among many other honors, Quinn is retiring from SLAC at the end of this year.

The seminar, sponsored by the Women's Interchange at SLAC, takes place from noon to 1 p.m. and is free and open to all.

Around SLAC:
Vacuum Chamber

The Heavy Fabrication Building's giant vacuum chamber is hard to miss, sticking out into the Building 26 parking lot like a toe through a well worn sock. Inside, it glows a dull orange, rock-hard epoxy hanging from the walls like little stalactites. The chamber is used to coat magnets with the stuff, the low pressure conditions (less than 1/360th of the Earth's atmospheric pressure) preventing any air bubbles from forming in the epoxy as it's applied. After nearly a decade of dormancy, the tank will be in heavy use this month, as engineers and technicians with SLAC's Heavy Fabrication Department prepare a batch of magnets for use in CERN klystrons.
