ADSC was very helpful in making some subtle adjustments to the detector gain maps so that the background of the images collected with our newly upgraded Q315r detector are much more uniform.
The "Before" image is a 2 second exposure with the multilayer optics and a fully tuned beam. In addition we had some plastic cover slips in the beam to generate background scatter. The "After" image is also a 2 seconds, but with the Si(111) optics and no plastic in the beam path. We will confirm that the gain remap has fully fixed the checker syndrome, but the initial images look very promising.
