1999
SPIE Conference on Accelerator-based Source of Infrared and Application.
The recent Annual Meeting of SPIE (July 18-23, 1999, Denver CO) hosted a conference dedicated to IR sources derived from accelerated electrons (or positrons) and its application to biological, chemical and materials sciences. Presentations addressed source and beamline issues, as well as techniques and scientific applications. The conference proceeding should be available later this year. SPIE conf. #3775..
The new
IR SPIG representative for 99/00 is Lisa Miller (NSLS).

U10B
IR microspectroscopy beamline continues operations.
The U10B beamline for microspectroscopy in the mid infrared has been operating for about 1 year. The current instrument is a Spectra-Tech Irus with scanning stage. A 100% line taken through a 3 micron metal pinhole is shown in the figure below.
This beamline will be operated by the NSLS with assistance from Northrop Grumman AST. Beamtime for external users is available through Lisa Miller. Check out the U10B link to see the Irus microspectrometer at the U10B beamline.
U12IR
initial operations.
The U12IR beamline for far and mid infrared spectroscopy been in operation
for more than 1 year. This beamline has two spectrometer endstations;
a lamellar grating interferometer for the very far infrared (2 to
100 cm-1) and a Bruker IFS 113v for the far and mid IR (10 to
6000 cm-1). Performance testing for the beamline and both
instruments continue, along with the PRT scientific program. Plans
are underway to replace one endstation with a Sciencetech SPS200 Martin-Pupplett
interferometer. Other new instrumentation will include an optical
immersion cryostat and high field magnet. Some beamtime for external
users can be requested at this time. Please contact Larry
Carr for information.
Mars
Meteorite investigated with IR microspectrometer at beamline U4IR.
Check out the Brookhaven
Bulletin (if you have Acrobat, you can go directly to Vol
51 No. 44, November 7, 1997). The ALH84001 meteorite specimen
has been studied by G. Flynn (SUNY) and collaborators using the Northrop
Grumman IR microspectrometer, temporarily installed at beamline U4IR.
The meteorite is a heterogeneous mixture of mineral phases, and Flynn uses
the microspectrometer to detect and identify the presence and location
of various organic compounds.
