Cool Magnetic Molecules

Certain materials are known to heat up or cool down when they are exposed to a changing magnetic field. This is known as the magnetocaloric effect. All magnetic materials exhibit this effect, but in most cases, it is too small to be technologically useful. Recently, however, an international collaboration of researchers from Spain, Scotland, and the U.S. has utilized ALS Beamline 11.3.1 (small-molecule crystallography) to characterize the design of such "molecular coolers."

AP-XPS Measures MIEC Oxides in Action
Using ambient pressure x-ray photoelectron spectroscopy on ALS Beamlines 9.3.2 and 11.0.2 , researchers provide the first in situ measurements of local surface oxidation states and electric potential in active MIEC electrodes (oxide materials that can conduct both electrons and oxygen ions), potentially valuable for high-temperature electrolysis and synthetic fuel production.

ALS Users' Meeting Update

Planning is well underway for the ALS Users' Meeting, which will be held October 3-5 (save the date). The meeting will consist of one and a half days of lecture, with several invited speakers emphasizing the relevance of synchrotron radiation in industry, an equal amount of workshop time, and the second annual student poster slam. The photography contest is back again by popular demand, and this year it will be open to everyone, so shutterbugs get your cameras out!

It's not too late to submit your ideas and workshop suggestions to meeting co-chairs This e-mail address is being protected from spambots. You need JavaScript enabled to view it and This e-mail address is being protected from spambots. You need JavaScript enabled to view it —just email by the end of May. The Users' Meeting Web site will be online soon; registration and poster submissions will open shortly thereafter.

General User Proposals: Statistics Posted; Next Cycles' Deadlines

Proposal scores for the July - December 2011 cycle have been finalized and users have been notified of their beam time allocations. The distribution of proposal scores and the cutoff scores for each beamline are posted online.

The User Office is accepting new General User Proposals from scientists who wish to conduct research at the ALS in the next cycle. Please visit our Web site for information on how to Apply for Beamtime, or follow the relevant links below:

PROPOSAL SUBMISSION DEADLINE for Structural Biology/ Biological SAXS Beamlines
Cycle: August - October 2011
Deadline: June 15, 2011

PROPOSAL SUBMISSION DEADLINE for all other (General Sciences) Beamlines
Cycle: January - June 2012
Deadline: July 15, 2011

BEAM TIME REQUESTS on ACTIVE PROPOSALS
Proposals for general sciences beamlines are considered active for two years, or until the total shifts requested in the proposal have been used. If you are the PI or experimental leader of an active proposal for which you would like to request beam time during the July-December 2012 cycle, you will receive an email with instructions.

APPROVED PROGRAM PROPOSALS:
Deadline: June 15 2011
An Approved Program (AP) enables an investigator or a group of investigators to receive an assured percentage of beam time for a period of up to three years to carry out an extended program of research. Users wishing to apply for an AP need to contact the ALS Deputy Division Director for Science. See the Web site for more information.

Safety Note: Summer's Here, but PPE at ALS Stays the Same

With hot weather arriving, ALS staff and users are reminded that Personal Protective Equipment (PPE) requirements remain the same year-round. Anyone working on the ALS experiment floor must wear long pants (or equivalent) and closed-toe shoes at all times. Shorts and/or open-toed sandals are not permitted at any time on the red floor! Read the ALS PPE guidelines.

Using the Staff Machine Shop David Osborne

Greetings ALS Users! Have you ever discovered that you need part of your experiment modified, and the changes needed require machine shop work? The ALS provides two options to help you solve your problem quickly and get back to data collection.

This e-mail address is being protected from spambots. You need JavaScript enabled to view it runs the staff machine shop in Building 80. For small jobs, Kurt can make modifications for you at no cost and generally with very fast turnaround time. For more involved machining, discuss with Kurt whether there will be a cost to your project.

As a second option, if you already have machining skills, you may obtain authorization to work in the staff machine shop. Plan ahead: the certification process takes about two weeks, and begins by contacting the ALS Safety Manager This e-mail address is being protected from spambots. You need JavaScript enabled to view it . There is some paperwork, and you'll need to take Kurt Krueger's machine shop safety course, but for the few people who need to make modifications themselves, the ALS provides this solution.

I want to thank both Jim Floyd and Kurt Krueger for their continued commitment to safety AND to finding solutions that keep your science progressing as rapidly as possible.

All users are welcome to contact their UEC representatives to raise issues of concern relating to their own research, or to alert us to issues facing our whole community.

opsinfoOperations Update
For the user runs from April 6 to May 1, 2011, the beam reliability [(time scheduled - time lost)/time scheduled)] was 97.2%. For this period, the mean time between failures (MTBF) was 61.0 hours, and the mean time to recovery (MTTR) was 118 minutes. There were no significant interruptions.

More detailed information on reliability is available on the ALS reliability bulletin board, which is located in the hallway between the ALS and the control room in Building 80. Questions about beam reliability should be directed to Dave Richardson ( This e-mail address is being protected from spambots. You need JavaScript enabled to view it , x4376).

Long-term and weekly operations schedules are available on the Web. Requests for special operations use of the "scrubbing" shift should be sent to Rick Bloemhard ( This e-mail address is being protected from spambots. You need JavaScript enabled to view it , x4738) by 1:00 p.m. Friday. The beam status in real time can be found on the ALS home page.
