Direct Kinetic Measurements of a Criegee Intermediate

“Criegee intermediates” are elusive molecules that play a pivotal role in atmospheric chemistry and are also byproducts of key combustion reactions. At the Chemical Dynamics Beamline, the reaction rates of one form of Criegee intermediate was directly measured for the first time, with some surprising results. Read more »PPT-icon-35 PDF-icon-35

Peter Denes, Head, Photon Sciences Initiative

I joined the ALS family in 2007, filling the newly created position of ALS Division Deputy for Engineering. Because a large percentage of ALS staff are part of the Engineering Division, this position was created to establish shared management in the two divisions to ensure better integration and coordination between engineering and non-engineering ALS staff.Read More Read more »

Christoph Steier, Accelerator Operations and Development

The operational performance of the ALS has improved continuously after overcoming the challenges presented by the injector upgrade to enable top-off operations in 2007. In the last six months, reliability, mean-time-between-failures and mean-time-to-recovery have reached levels never before achieved at the ALS (see this month’s article “Twelve Superlative User Weeks at the ALS”). This includesRead More Read more »

Paul Adams, ALS Division Deputy for Biosciences

In my new role as ALS Division Deputy for Biosciences I am working with bioscience researchers at the ALS to develop an integrated strategic plan. Lab Director Paul Alivisatos, Physical Biosciences and Life Sciences Division Directors, and ALS leadership identified this activity as important for the future of Lab biosciences, and for making a caseRead More Read more »

Elizabeth Moxon, ALS Communications Group Leader

How do you explain how a synchrotron works to a fidgety five-year-old and her tired parents? Well, you turn her into an electron, hand her a ping-pong ball “photon” and send her careening around a synchrotron obstacle course that has been painted in brilliant colors on the ALS parking lot. After she “accelerates” down aRead More Read more »

Ben Feinberg, Interim Deputy Director for Science

Although officially retired, in May I agreed to help the ALS part-time in light of Bob Schoenlein’s new role helping to plan for a next generation light source at Berkeley Lab. As the ALS Interim Deputy Director for Science, I now have the opportunity to work with a different part of the ALS organization thanRead More Read more »

Two Novel Ultra-Incompressible Materials

Materials that are mechanically, thermally, and chemically stable at extreme conditions are valuable for aerospace engineering and fission/fusion research. Researchers have synthesized and characterized two such materials: Re2N and Re3N are both extremely incompressible. Read more »PPT-icon-35 PDF-icon-35
