====================================================
Beamtime available at CHESS, Feb. 7 - June 4, 2018
====================================================
The CHESS/MacCHESS facility, located at Cornell University in Ithaca, NY,
invites macromolecular crystallographers and users of BioSAXS to apply for time
on one or more of our stations:
F1 station, monochromatic wiggler source, suitable for crystallographic data
collection, at an energy appropriate for Se SAD phasing. Equipped with Dectris
Pilatus 6M detector and ALS-type automounter.
G1 station, undulator source with multilayer optics, suitable for BioSAXS
experiments, equipped with dual Pilatus 100-K detectors, automated
sample-handling, in-line SEC-SAXS capability; good data can be obtained over
q-range 0.006 - 0.7 (1/Å).
For 1 week only - G3 station, undulator source with multilayer optics, equipped
for crystallography, with Pilatus 6M detector (no automounter for this test
run). The hottest beam at CHESS!
===== Special options ======
Pressure cryocooling of (unfrozen) crystals is available by prearrangement.
This method can reduce the damage induced by cryocooling, often with no need
for cryoprotectants (Kim et al., Acta Cryst. D61, 881-890 (2005)). In some
cases, it can reduce initial disorder (high mosaicity, anisotropic diffraction,
some kinds of twinning). Contact Marian Szebenyi ([log in to unmask]) for more
information on pressure cryocooling.
High-pressure and time-resolved BioSAXS techniques are under development and
are available on a collaborative basis. Contact Richard Gillilan
([log in to unmask]) if you are interested in cutting-edge BioSAXS work.
======= Support =======
CHESS/MacCHESS provides a high level of support for all users. We are
very willing to help with non-standard experimental setups - just ask.
Our staff scientists also invite collaborations for more extended
projects investigating novel techniques.
Remote data collection is available, as well as mail-in service.
======== Applying for time ========
Apply on-line at http://userdb.chess.cornell.edu. Applications are accepted
at any time, but early submission assures that we will have time to fully
evaluate your proposal (especially if you have any special needs).
