Deep Underground Science: New Issue of Symmetry Online

If you're a dark matter particle or a neutrino, it's a constant struggle to make yourself heard. The universe is an exceptionally noisy place, filled with a rain of cosmic-ray particles—mainly high-energy protons. One of the few places to escape the noise is deep underground, where the rock, earth or water above shields against cosmic rays and allows other particles to tell whatever they are trying to say.

This issue of Symmetry explores a range of particle physics and other sciences that can be be performed only deep underground.

Some highlights of the issue: plans for a U.S. deep underground science and engineering laboratory, taking clean equipment to an extreme in the Enriched Xenon Observatory in a salt deposit in New Mexico, the trial faced by the earthquake-stricken Abruzzo region and the Gran Sasso laboratory in Italy, the search for "dark life", and a day in the life of the Soudan underground lab in Minnesota.

A Visit from George Shultz

Former U.S. Secretary of State George Shultz, presently a distinguished fellow at Stanford University's Hoover Institution, visited SLAC last week together with several colleagues, national security fellows in residence for the year at the Hoover Institution and Center for International Security and Cooperation at Stanford. After lunch with SLAC Director Persis Drell and Hoover Senior Fellow Sid Drell, the group toured the lab.

The group visited the Klystron Gallery, then John Galayda, director of construction for the Linac Coherent Light Source, guided them through the LCLS Undulator Hall and Far Experimental Hall for a glimpse into the workings of the worlds' first hard X-ray laser.

Colloquium Today:
A New Generation of Particle Accelerators

Particle accelerators and their associated technologies impact many aspects of our lives, from the inner workings of a microwave oven, to industrial processing of materials, to modern treatments for cancer, to keeping us safe. Tremendous technical progress in the last two decades has radically changed the landscape, transforming fantastic concepts into tangible reality. We'll take a look at how far these technologies have come, and what the future might hold.

Eric Colby is the acting head of the Advanced Accelerator Research Department and a senior scientist at SLAC. Eric has worked for more than two decades on a variety of accelerator research from particle and microwave sources to advanced concepts for accelerators. He is the spokesman of E163, an experiment to demonstrate techniques for accelerating particles with light.

The talk will begin at 4:15 p.m. today in Panofsky Auditorium. The colloquium is free and open to all.
