Everything continues to go very well. Yesterday we successfully aligned the laser metrology system using the mast adjustment mechanism so that the lasers are close to the centers of the metrology detectors. Kudos to Bill Craig for getting the alignment correct (not an easy job) and to the Caltech team for their quick and expert analysis correction calculating the required adjustment. Kristin also has analyzed the mast motion and determined that the model expectations for the motion are dead on.

We also turned the anticoincidence shields on yesterday, and took data to validate that they are functioning properly. Today we turned the CZT detectors on, and they are functioning nominally. Overnight we'll took our first real background data.  Analysis ongoing.
