ACA Summer Course

[John P Rose]

                            Preliminary announcement

    THE 4TH ACA SUMMER COURSE FOR CRYSTALLOGRAPHY, PITTSBURGH, PENNSYLVANIA
		                 AUGUST, 1995

 	A fourth Summer Course will be offered over the period August 1-13, 
  1995.  As before, it will take place at the University of Pittsburgh.  The
  aim is to provide a group of about 30 participants with a quick intense 
  introduction to the basics of crystal structure determination and analysis:
  how to collect single crystal X-ray diffraction data, how to use associated 
  software to solve and refine a crystal structure and how to analyze the 
  results.  Graduate students, postdoctoral fellows, service crystallographers
  and crystallographers from corporate and other laboratories are invited to
  apply for admission. Participants should have some prior experience in small-
  molecule or protein crystallography as presented for example in "Crystal 
  Structure Analysis: A Primer" by Glusker and Trueblood.

	The Course will emphasize the basics of crystallography and will be 
  divided approximately equally between lectures and laboratory sessions.  It 
  will involve primarily the determination of small-molecule structures with 
  samples brought by participants.  For those especially interested in protein 
  crystallography, there will be several lectures on protein crystal growth 
  the phase problem in macromolecular structures, but there will be no 
  and opportunity for practical work in this area.

	In advance of the Course, participants will be provided with the 
  Lecture Notes from the 1994 Course, also available from Polycrystal Book 
  Service, (PO Box 3439, Dayton, OH 45401-3439).  The University of Pittsburgh 
  has single-crystal diffractometers with the associated structure
  determination  software packages fom all three major vendors (Enraf Nonius 
  CAD-4; Siemens P3 and Rigaku AFC-5) and these will be used round-the-clock 
  throughout the Course.   According to their choice of diffractometer,
  participants will be assigned to a small group which will work on this 
  instrument under the guidance of tutors and vendor representatives.

	Tuition for the Course will be $560.  Three full-tuition and seven 
  half-tuition scholarships will be awarded on a competitive basis.  Air-
  conditioned dormitory accommodations will be available through Pitt Student 
  Housing.  The cost (1994 rates) will be approximately $24/day single or
  $30/day double occupancy.  Student housing is only a short walk from the
  Department of Crystallography where the lectures will be given and an equally
  short walk from  the sites of all the diffractometers that will be used.

	Applications should be made on forms available from Prof. Bryan Craven,
  Department of Crystallography, University of Pittsburgh, PA 15260.  Phone:
  (412)-624-9300; FAX: (412)-624-1882.  In order to be eligible for financial
  assistance, an applicant must return the completed form to Prof. Craven no 
  later than May 31, 1995.
