SCSB Crystallography News

Problem with DIP2030 Detector Solved: Over the last month the Mac Science DIP2030 detector system has has intermittent periods of failure, sometimes stopping or producing rotated images. I dismantled the detector and ran tests on the unit. Eventually, I was able to recreate the errors and trace the problems to a single cause: a worn mechanical component which locks the Image plate into position. Replacement of the worn component has solved both of the problems. The detector is now functioning perfectly.

MOSFLM, PHASER and CCP4-5.0.1 are now installed and operational on our Linux workstations. HKL2000 will be available soon.

Why wait two weeks? Skip the queue! The waiting list for the DIP2030 detector, equipped with the new MSC Blue confocal optics is now averaging two weeks. The SMART2K CCD detector system, which still has the older Gobel optics, is available for larger crystals (> 0.2mm) which diffract reasonably well. So don't wait, hop on the CCD, the queue is much shorter.

Let The SCSB Advance Your Research

The SCSB is here to facilitate your Structural Biology research.

Research Areas



  • User Training

  • Mentoring

  • Collaborations

User Training

The SCSB staff is always ready and happy to train your students, post-docs and technicians in the correct use of the SCSB Instrumentation. They will also pick-up a few helpful hints along the way also. The support of the SCSB and the assistance by the staff member(s) should be acknowledged in any publications.


If you do not have the expertise to perform certain types of research the SCSB staff or faculty may be able to mentor your graduate student or post-doc as a collaborative project. Mentoring requires a significant commitment by both the mentor and student learning a new field of research. The Mentor should be co-author on any publications resulting from the student's research project. The support of the SCSB should be acknowledged in any publications.


Please contact any SCSB researcher (PI) or Core Manager to discuss possible collaborate research projects. Of course such projects are at the discretion and time-restraints of the collaborator. The Collaborator should be an author on any publications resulting from the collaborative research project. The support of the SCSB should be acknowledged in any publications.
