LCLS CXI Instrument Receives First X-rays

X-rays entered the Linac Coherent Light Source's Far Experimental Hall for the first time Saturday, as part of commissioning for the Coherent X-ray Imaging instrument. The team of instrument scientists, accompanied by many staff members of the Photon Controls and Data Systems groups, other LCLS staff and a few onlookers welcomed X-rays to CXI shortly before 2:30 p.m. This was followed by several hours of SLAC Radiation Physics Department surveys and validation of the instrument hutch.  Read more...

SLAC Users Organization Elections Open

The polls are open for the election of the 2011 members of the SLAC Users Organization Executive Committee. This year we will be electing four new members to fill rotating three-year terms. The outgoing members are Henry Band, Gerard Bonneaud, Michael Peskin and Steve Sekula. We thank them for their service.

All members of the SLAC Particle Physics and Astrophysics community are invited to participate. Online voting is open until midnight on Sunday, December 19.

More information about SLUO can be found online on the SLUO Web site. If you are not yet a member, please consider joining.

SLUO represents the interests of SLAC particle physics and astrophysics scientific users to the lab management, to funding agencies and to members of Congress in Washington, DC. Please do your part to see that SLUO has as strong a leadership as possible. Please vote.

New Facilities Request E-mail Notifications Start Today

In an effort to improve communications with our customers, the Facilities Division has implemented an e-mail notification system, beginning today. Facilities customers will be notified when any of the following items on their requests are updated.

  • A service request is changed to a work order.
  • The priority is changed.
  • The due date is changed.
  • The work order status changes.

In order to avoid sending multiple e-mails for each individual change, the system will send out a summary of the changes to a given work order. This summary will go out at 2 a.m. if any of the four items above were updated the previous day. Each update will also include a full history of the work order.

Customers will be able to "opt out" of notifications as well.

To check on work orders, customers can always go to the Facilities Web site (use the "Search Requests" link at the top left) or call the help desk (x8901).

Colloquium Today:
The First Year of SXR

Today at 4:15 p.m. in Panofsky Auditorium, Bill Schlotter, instrument scientist with the Linac Coherent Light Source Soft X-ray Instrument, will present the final colloquium of the quarter: "Studying Materials with the LCLS: The First Year of SXR."

Dedicated to materials research with soft X-rays, the SXR instrument took first light from the LCLS on May 6, 2010. Following commissioning the instrument launched into a diverse set of user experiments, ranging from studying the ultrafast dynamics of magnetic systems to the evolution of molecules on catalytic surfaces, and even matter under extreme conditions.

The ability of the SXR instrument to adapt to such a wide range of experiments is born out of the diverse set of user-provided experimental end-stations that are rolled in and temporarily connected. X-rays from the LCLS are delivered to these end-stations through the SXR beamline, which can tailor the X-ray bandwidth and spot size for each experiment.

The first user run has revealed a better understanding of the interaction of intense free-electron-laser soft X-rays with matter and demonstrated the viability of many soft X-ray techniques at the LCLS. The SXR instrument is the second instrument at LCLS to take beam, and the most recent instrument to begin user experiments. SXR was initiated and supported by an international consortium that realized a need for a soft X-ray spectroscopy, scattering and imaging beamline. As a result, the outstanding operation of the LCLS combined with a knowledgeable and dedicated user community has produced a world-class tool for understanding materials.

Today's talk is free and open to all. This is the final colloquium for 2010.
