While on the topic of mail-in facilities and readily available neutrons for the powder diffraction community (North American based in this case).
The C2 neutron powder diffractometer at Chalk River, Ontario, Canada has a rolling proposal system where users can submit beamtime proposals at any time. After the proposal has been approved, users often take the option of using a mail-in system. C2 is an 80 degree, 800 wire PSD system. Web information: English: http://neutron.nrc-cnrc.gc.ca/c2gen.html Francais: http://neutron.nrc-cnrc.gc.ca/fch/c2gen.html Proposal form is available on the web (and again, can be submitted at any time as part of rolling review process): http://neutron.nrc-cnrc.gc.ca/propfrm.html http://neutron.nrc-cnrc.gc.ca/fch/propfrm.html ---------- If requiring data for solving structures by Fox (or similar structure solution programs): Sample run at ~2.37 A (single bank 5 to 85 degrees 2-theta) For refining: Sample run at ~1.33 A (two bank merged data, 5 to 115 degrees 2-theta) If unit cell "accuracy" (rather than "precision") is required at a range of temperatures (including RT): Extra run at ~1.33 A with high purity platinum foil standard, single 80 degree bank of data. ------------ Lachlan -- ----------------------- Lachlan M.
