2008 News from APS Sector 7

  • December 2008:
    • 12/2/08 The APS User News-at-a-Glance Issue 50 is out. Note the story about the APS Renewal, Neutron/X-ray School, etc...

  • October 2008:
    • Please note that the deadline for General User Beamtime Requests and New Proposals is fast approaching. Requests or new proposals are due Friday Oct. 31 2008. The laser will be running at 1 kHz for the winter run of 2009-1. In the winter of 2009, we should have all the instruments available for experiments.

      As far as laser experimental capabilities for the current run 2008-3, Coherent visited Sector 7 from Oct. 14-16, 2008. The laser was set to run at 5 kHz, with power and pulse lengths comparable to previous runs. We finally obtained a laser permit for 7ID-E and for limited scope operation in 7ID-C on the 6-circle diffractometer last week on Thursday Oct. 23, 2008. This new permit for 7ID-C required a set up specific "mini-SOP" that details the optical path and beams available on the 6-circle. The laser ran over the past weekend, and after fixing some timing problems last Monday, Don Walko was able to take time-resolved data. We'll contact users with beamtime requests for 2008-3 shortly.

    • Please note that a new article entitled "Empirical dead-time corrections for synchrotron sources" by D. Walko et al. has been published in J. Synch. Rad.. The article is available here. Congratulations to all involved!
    • A preliminary schedule of 7ID has been posted on 10/13/2008 on our web site (Operation link).
      Yuelin Li has schedule a laser repair visit by Coherent on Oct. 13-14. They will replace
      many optical components and switch the laser repetition rate to 5 kHz. The laser will stay at
      5 kHz during the 2008-3 run. We are hoping to get a laser permit shortly thereafter, possibly by Oct. 17.
    • The 7ID beamline is looking to hire a Scientific Associate immediately to help support the 7ID Ultrafast laser program. If you know any suitable candidates,
      please let them know to contact Yuelin Li or Jin Wang for additional details. Here is a direct link to the position description.
      The ANL Job search site is available here (search for position ID 313791 XSD Scientific Associate for 7ID).

  • August 2008:
    • On August 26, the XOR7 team requested to postpone the announcement of the results of the GUP competition for beamtime on 7ID because of delays in restarting laser operation following a laser incident. Some details of the incident can be found here as reported to DoE in an ORPS notice. An investigation of the incident is ongoing and laser operation will not retart until it is completed. A draft of the report is expected around September 12, 2008.
    • We are pleased to announce that Yuelin Li formerly from the APS Accelerator Division joined Sector 7 at the end of August.
      Here is an APS wide announcement of this good news. Yuelin has a vast experience with amplified Ti:Sapphire system so will be the new LCA supervisior for the 7ID-E laser.
  • July 2008:
    • Sincere congratulations to the group of Prof. David Reis for their recent publication in Phys. Rev. Lett..
      The work was recently displayed on the APS web site. In the same month, Prof. Reis's group also published an article in Phys. Rev. B
      (See Sheu et al. in the publication section of this web site).
    • At the end of July, Eric Landahl left Sector 7 and the APS to take a faculty position at DePaul University in Chicago. Eric led many significant upgrades to the laser facility at XOR7 in the past 5 years (completely new Ti:Sapphire laser, new laser enclosure, etc...). He will be dearly missed. This is certain to affect our laser-pump x-ray probe program for the near future.

  • August 2006:
    • There are major news for the future of the 7ID beamline to announce.
      During the Aug.10-11 Summary Workshop of the APS Upgrade, a fast-track
      project to implement the Zholentz RF Crab-cavity picosecond source will be 
      implemented by September 2007. An x-ray beam with 120 Hz repetition rate and a
      few picosecond duration will be demonstrated on 7ID during hybrid mode operation
      using pulsed RF cavities. See on the link provided above the talks by George
      Srajer and Linda Young for more details on the projected scheme. This will open
      new opportunities for pump-probe experiments at the APS. The sector staff is
      quite excited with this news and will work to implement the x-ray optics and
      timing signals required to use this new capability in 2007.

  • March 2006:
    • The experimental run 2006-1 is going well overall. We are currently planning to
      install a new monochromator to replace the aging cryogenic monochromator in
      7ID-A. We are hoping that it will be installed in the May 2006 shutdown. The
      monochromator would be a standard APS Kohzu monochromator with watercooled 
      diamond (111) crystals. We hope that it will provide reliable scanning for the
      increasing demand of spectroscopic experiment on 7ID. The watercooling may also
      improve the beam fast time scale stability. Diamond (111) crystals may reduce
      the throughput a bit though while improving the energy resolution some. This
      depends very much on the quality of the diamonds. The monochromator comes from
      S32, and has performed well there. We plan to do extensive commissioning after
      it is installed, thus it may affect the beamtime available for user experiments
      on 7ID this summer. We will try our best to provide as much beamtime as possible
      for user experiments this summer.

    interesting note for example about how to handle a broken Be window. Note also that the final report
    on the Pb surface contamination in 7ID-C and D confirmed that the area are now free from excessive Pb.

    The APS hosted the Three-Way Meeting (APS,ESRF,SPring8) on June 2-3. Many of the talks
    are available on-line along with the meeting agenda. See this link for further details

    In May, ANL hosted the IndoUS Workshop on Radiation Physics with Synchrotron and Other New Sources
    (See this link here ). Photos taken at the workshop are also available here..

  • May 2003: The new schedule was posted on May 8, 2003 in the operation section of the web site.
    See the schedule here for more details.
    The shutdown has been busy with a list of activities one can see on the operation section.
    On 5/21/03, the APS launched its new ESAF approval system. From now on,
    MHATT-CAT Users must submit their ESAF online at least 7 days in advance
    for simple experiment not involving hazardous activities, and MHATT-CAT as
    well as the APS must approve the experiment before it can start. See my email message for more details.
  • February 2003: See the news story of COBRA on the APS web site Science tab!
    Find here my MHATT-CHAT email on Summer 2003 conference deadlines, etc...

  • January 2003: See the schedule for the second run of FY03 on the MHATT-CAT operations page.
    Several activities occured during the January shutdown and a brief summary can be found also here.

    MHATT-CATers in the news: Please note that the work of Paul Evans (Wisconsin) and Yong-Ah
    Soh (NEC) started on 7ID and completed on 2ID was reprinted in Physics today in January 2003.
    The article is "Mesoscopic Texture in Manganites," by Neil Mathur and Peter Littlewood.

  • 2002 News from APS Sector 7

  • December 2002: See the Physics Today news story on the COBRA experiment in the Dec. 2002
    issue (p9 in Physics Update)! Note also that our publication list has been updated.
    On major instrument update, the 7ID-D set up was improved by commissioning a Huber 4 circle with a
    vertical diffraction plane. The local staff thanks Dave Fritz and Adrian Cavallieri for their help in
    commissioning the instrument. In Dec., we also tested a new arrangement of Li lenses to focus in 2D.
    A brief report can be downloaded here.
  • October 2002: Yizhak Yacoby and his collaborators made the cover of the first issue of Nature Materials!
    This is very exciting news for the COBRA team! See the Vol 1 No2, October 2002 issue for the full story.

  • September 2002: In late September, Don Walko and Eric Dufresne in collaboration with Tom Trainor and
    Peter Eng from GSE-CARS upgraded the Kappa control program to take data scans
    on-the-fly. This new mode will significantly reduce the time taken to take data
    with the Kappa in 7ID-C.
  • August 2002:The MHATT-CAT web server has now moved to a new server.
    The web site was edited and suggestions for changes are appreciated.
    At the beginning of August, we commissioned a new set up to perform microdiffraction
    on the Newport Kappa in 7ID-C with a pair of K-B Mirrors. (See the news story here).
  • July 2002: President Bush visits the APS on July 22 (See the pictures here)
  • April 2002: MHATT-CAT is pleased to announce its first
    workshop on Ultrafast X-ray Science scheduled for June 5 and 6 2002 at the APS.
    Please contact Prof. David Reis for details.

    Some of our Lucent members were in the news recently in the April 2002 issue of
    MRS Bulletin, page 288. See the news story on the Lucent/APS/NEC project.

  • March 2002: A news brief of the work on the Li lenses appeared in the SPIE
    OE Magazine in March 2002 (p10). It was followed shortly by a news story in
    Photonics Spectra (March 2002, p20).
    The new flats for the CARS style KB Mirrors to be used on 7ID were found to
    work very well during a UofM Geology experiment. Preliminary results show that
    the beam can be focussed to about 2.5 um by 2.5 um FWHM without too much work!
    The mirrors were purchased from WavePrecision, formerly known as General Optics.
  • Another article has been published in Nature on work done at MHATT-CAT!
    The article authored by the ORNL microbeam group starts the field of
    Three-dimensional X-ray structural microscopy with submicrometre resolution.
    Congratulations to the group led by Ben Larson and Gene Ice on very nice work!
