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.

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.

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.

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!

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!
See also the News and Views article describing the results.
- The Ultrafast Bragg Switch experiment performed in 7ID-D was covered
recently in Physics Today! See the February 2002 Physics Update here.
