Two ALS Users Selected for DOE Research Award Print

Berkeley Lab Scientists Kevin Wilson and Oliver Gessner have been selected from a nationwide pool of more than 800 applicants to receive research awards from the DOE’s Early Career Research Program. Wilson and Gessner join 66 other U.S. university- and laboratory-based researchers who were selected for the five-year awards.

Overseen by the DOE’s Office of Science, the Early Career Research Program provides crucial financial support to top researchers in their formative career stages. With these awards, the DOE specifically targeted research areas that are high priority to the department and the nation as a whole.

wilsonWilson, Beamline Scientist on the Chemical Dynamics Beamline 9.0.2, plans to focus his Early Career research on the fate of hydrocarbons in the environment. His research will use new experimental techniques to look at how hydrocarbons at the liquid-water interface react with gas-phase free radicals. “It was my beamline work here at the ALS that led to some of these questions about how chemical reactions occur on the surface of organic aerosol particles,” says Wilson.


Gessner, also associated with the Chemical Sciences Division, will concentrate his Early Career research on gessnermolecular electronic function. Gessner’s work will use intense, ultrashort x-ray pulses to monitor the light‐induced creation and transport of charges in complex molecular systems. Some important proof-of-principle work that went into Gessner’s proposal was conducted at the ALS, exploring the unique capabilities of the light source in combination with pulsed optical lasers. “There’s so much expertise here in the fields of x-ray spectrometry and the physics of condensed phase systems,” says Gessner. “Our work at the ALS provided a great base to build on as I crafted my proposal.”

The awards serve as a rare opportunity for both scientists to delve deeper into their work and craft well-rounded research programs. “It’s a rare opportunity to really focus on a single problem and to put together a scientific program around it,” says Wilson.

“This early career award will allow me to grow this work into an actual program,” says Gessner. “It’s very gratifying to see the DOE acknowledging our work in this manner.”

Twelve Superlatve User Weeks Print

September 28, 2011

Twice this month, the ALS achieved a 12-week running average reliability of over 99%--something without precedent according to Dave Richardson. The most recent 12-week running average for MTBF was above 78.5 hours, and the MTTR was 38 minutes. See charts below for detailed information. Congratulations to all who helped achieve these successes!


Summer 2011 Shutdown Update Print

The 2011 ALS summer shutdown is turning out to be quite productive. Read updates of shutdown activities and see pictures here. This page will be updated, so check back regularly!


THE DOME of the Building 6 roof is in need of repair both inside and out


The exterior of the roof is nearly re-shingled! See the newest images here, taken from atop the dome!


Construction crews built scaffolding around the outside of the dome's roof so they could access the whole dome safely.




















Asphalt shingles that used to leak during heavy rains will be replaced with "cool roof" technology.












The dome is half done in this photograph. You can clearly see the old (bottom) and new (top) shingles!










Construction crews have been hard at work all month reroofing the ALS dome! What a gorgeous view they get from the office!



















It's nearly complete. The ALS's new "cool roof" will be complete soon!












No update on the dome's interior. The plastic sheeting is still in place. Stay tuned to see the final result...


Scaffolding was built on top of the large crane in the ALS building. Workers will be scraping lead paint away from 30% of the dome's interior. A "lead lock" coating will then be applied to protect occupants from exposure to the remaining lead paint.












A plastic sheet now hangs between the interior of the dome roof and the delicate controls below. This will prevent stray pieces of hardware or lead paint chips from falling.











Super Bend Magnets get new cold heads - every year



This is one of the ALS's three super bend magnets (super conducting center bend in SR 4, 8, and 12). The cold heads (helium compressors) on the magnets must be swapped out every year. This involves warming the magnets up from their sub five kelvin operating temperature, breaking the vacuum, swapping the cold head, reestablishing the vacuum and cooling the magnet back down. This process takes a minimum of three weeks and is one of the things that drives our need for an annual extended shutdown.


















Sector 6 gets ready for a new Elliptically Polarizing Undulator




This EPU has been undergoing magnetic testing in the building 15 high bay for several months. It's final location is expected to be in sector 6.
























This new vacuum chamber was installed during the shutdown, as well as a new chicane magnet. These preparations have prepared this downstream section of straight 6 for the new EPU, which will be installed over several 2-day shutdowns in the coming months.












POWER SUPPLIES are also being replaced during this shutdown. An old QFA and an old SD power supply were both removed in preparation for newer models.



Crews remove the old sextupole power supply using a counter weight and a 4-ton crane. Two new sextupole power supplies will replace this old one, providing a tested backup should it ever be needed.
















The old QFA power supply was also removed in preparation of a new one. The new QFA will be less sensitive to line voltage sags that cause beam dumps. Both power supply upgrade projects will aid in more reliable beam delivery, but are mainly to replace aging equipment and keep the ALS running smoothly.

Students in Uruguay Collect Protein Crystallography Data at the ALS Print

The Institut Pasteur de Montevideo (IPM) in Uruguay introduced students to remote protein crystallography data collection with the help of Peter Zwart at Beamline 5.0.2. A two-week, international workshop on macromolecular crystallography (MX) and its applications instructed 20 PhD students, postdocs and research assistants on the complete MX process.

ALS Controls Upgrade: Meeting the Needs of a Growing Facility Print

Users may never notice it, but a major controls and instrumentation upgrade is underway at the ALS. Over the next four years, the controls system that runs all aspects of the synchrotron, from injection to magnets, will be decentralized and its instrumentation replaced. These improvements will coordinate with recent software upgrades to improve efficiency, beam stability, and “disaster scenario” control.

Optical Metrology Lab Receives New Funding for Upgrades Print

The Optical Metrology Lab (OML) at the ALS is renowned for its precision and technical expertise in metrology of x-ray optics. It has achieved this notoriety with only two full-time staff members and extremely limited laboratory facilities. Now, with new funding from the DOE that provides $1.2M to build a new clean room laboratory with environmental controls, and the promise of $1.4M to upgrade and replace outdated instrumentation, the OML will be able to achieve an even higher level of excellence.

Solving Structures with Collaborative Crystallography Print

The Berkeley Center for Structural Biology’s Collaborative Crystallography (CC) program is making major advancements in solving protein structures, especially for users involved in high-throughput projects. The CC program is an NIH-funded, peer-reviewed service that allows external users to apply for both beam time and the support of a crystallographer to perform experiments and subsequent data analyses.
