The service crystallography laboratory is located in the Department of Chemistry at the University of Toronto. The X-ray Facility is used by departmental members but is also available to outside users. The service manager, Dr. Alan Lough , deals with all aspects of the service from crystal selection to publication of the results. Additional advice and expertise are provided by Prof. D.H. Farrar. Operating costs are recovered from users of the service and a Facilities Committee oversees the entire operation.
