In November, we had a one week beam time at CHESS in Cornell University. We measured rocking curves for several diamond crystals there. Some interesting results are shown below.
- Results for the 20 micron diamond
- Discussion about the X-ray beam divergence
- How the crystal curvature affects the rocking curve width
One of the challenges we faced during the 2006 feasibility measurements at CHESS was how to sufficiently collimate the beam to resolve the rocking curve structure of diamond on the scale of its natural Darwin width. The following studies were carried out to understand why this was difficult to do given the standard C1 beam line configuration, and how it might be improved for diamond diffraction measurements.
