For the last six years, the Macromolecular Crystallography Research Resource (PXRR) has been providing mail-in access to several beamlines at the National Synchrotron Light Source (NSLS) for X-ray diffraction. This program is available at no charge for academic users from the US and around the world. This service has fostered a new paradigm for collaborations between the local staff scientists and synchrotron users. It also accelerates the innovation of new productivity tools, which benefit users who come to NSLS beamlines as well as those who use the mail-in program.
