Calibration tests and use of a Nicolet/Xentronics imaging proportional chamber mounted on a conventional source for protein crystallography

The results are presented of calibration tests and several single-crystal X-ray data collection experiments undertaken with a Nicolet/Xentronics Imaging Proportional Counter mounted on a conventional X-ray source. Considerable attention has been given to system optimization in collaboration with Nicolet, and this has led to a performance of high quality.
