We have a Bruker D8 Advance using Cu radiation with both a scintillation detector as well as an energy dispersive one Images and details of the shutter can be examined. We have designed and built a new shutter for a Picker diffractometer. Single-crystal Diffractometer Shutter: back to top Here is some info on using our Single code to run motors for translation devices. We are working on Windows algorithms for this. Motors on diffractometers need to be moved. We use the Cameca SX-50 at the Department of Lunar and Planetary Sciences, managed by Ken Domanik. We use titanium pins and orient along the axis of the pin and the perpendicular direction indicated by a fudicial mark on the side of the pin. The crystal can then be fixed to any sort of holder. The user chooses two crystallographic axes that are oriented 90 deg from each other and the crystal is rotated into that orientation. The orientation matrix of a sample is obtained on the X8, then the sample is transferred to the Orienter. New motors and controllers were assembled and the machine operates through an in-house Windows dialog box application. It is a rebuilt P4 with Kappa geometry that was completely stripped of all electronics and hardware related to diffraction. This is the simple-minded name that we gave to a machine that we built to orient crystals. It runs under Kappa geometry with a full suite of Bruker software for data analysis. It represents Bruker's state-of-the-art small lab diffractometer.

The Bruker X8 was provided to the lab by a private donor with matching funds from the College of Science. It operates under Eulerian geometry and uses a point detector preceeded by both a cylindrical and a double-slit collimator. The Picker was obtained from Charlie Burnham's lab at Harvard in 1997 andĪutomation is accomplished with in-house software, providing the flexibility to attack a problem from any configuration. One is an automated Picker mostly for high-pressure work,Īnd the other is a Bruker X8 Apex diffractometer equipped with a 4K Apex II CCD detector for general crystallographic studies. We have two operating single-crystal diffractometers: Single-crystal Diffractometers: back to top Home - research - lab - personnel - software - linksįortran-based software to control stepper motors.
