SLAC Today

Monday - June 23, 2008

Can You Hear Me Now?

Ron Badger is standing inside what looks like a cave, but is actually the windowless belly of Building 136. And just like a cave, the thick cement walls make cell phones go dead at the threshold. Badger is standing near a stack of black receivers as he picks up his radio and calls to someone half way across campus. They answer back loud and clear.

The SLAC radio and pager system allows employees and visitors to communicate 40 feet below ground in the accelerator tunnels, inside the PEP and SLD ring tunnels, and out to the far corners of the campus. It all works through a simple set of relays.

If Mike Harms is above ground trying to send a page or communicate by radio with Badger who is in the tunnels of the accelerator or inside a dense building, his radio will broadcast a signal that gets picked up by one of three large antennae on campus. They are located at the repeater Building 443 (on the hill above the research yard), at Building 136 and at Sector 1 of the beam line. The signal is captured by the antennae, which runs it through a system of cables that extend through many tunnels and buildings on campus. The cable releases the radio wave—or "leaks" it—into the tunnel where Badger's radio picks it up.  Read more...

Colloquium Monday

The Current Food Crisis: Causes and Consequences

(Photo - Walter Falcon)In this afternoon's colloquium, Stanford University Professor Walter Falcon will speak about the unusual nature of the current food crisis and how it is being felt around the world. In looking forward, he will specifically address the potential role of genetically modified organisms (GMOs) in feeding a world of 9 billion persons in 2050.

Falcon is deputy director of the Food Security and the Environment Program, former director of the Freeman Spogli Institute for International Studies, and Farnsworth professor of International Agricultural Policy at Stanford University (Emeritus).

A specialist in agricultural policy in developing countries, Falcon current research focuses on agricultural decision-making in Indonesia and Mexico, and on biotechnology, climate change and biofuels.

The colloquium takes place this afternoon at 4:15 p.m. in Panofsky Auditorium. All are invited to attend.

Celebrate Jonathan: Registration Continues

A symposium honoring Jonathan Dorfan's distinguished career at SLAC and his leadership in the broader scientific community is scheduled for July 24, 2008.

The symposium will include talks by longtime friends and coworkers. In the afternoon, the event will move to the SLAC green, where all attendees are invited to enjoy ice cream and cake. The day-long event will conclude with a reception and dinner at the Stanford Faculty Club, where Stanford President John Hennessy will speak.

Simply visit the event website to register.

 

Shipping and Receiving Delays Anticipated

Due to the shortage of resources and requests for vacation over the summer period, Shipping and Receiving will be experiencing some delays in its delivery of received items to customers. At some time over the next few weeks there may be a 2-3 day lag in the delivery time. Customers may contact Sandra Pickrom (x4247) if they foresee any special need for the rapid delivery of an item.
