BEAMLINE TOOLS Accessed by the robot are certain beamline tools: YAG Crystal or Phosphor: on either 22-ID-D or 22-ID-E, YAG crystal will be preferrable for aligning your beam (mounted on same stage as crystal alignment slides); in principal, phosphor could also work, and one will be available on both 22-ID-D and 22-ID-E, phosphor is first step towards verifying that goniometer height coincides with cross-hairs (and is aligned with x-ray beam) Alignment pin: used to ascertain "point and click", "goniometer rotation axis" a sharp-pointed pin, available for "point and click" verification successful alignment of tip at all goniometer orientations verifies goniometer rotation axis coincides with cross-hairs (used for "point and click", as well as alignment of x-ray beam position) Trypsin crystal (standard; primitive orthorhombic, space group P212121) though this crystal may appear icy towards the end of the run, it will continue to diffract well and provide an in-house standard for beamline verification
