The Precision Metrology Group was originally established to provide Fermilab’s two colliding beam experiments, CDF and DZero, with the precision alignment of their silicon detectors. As a result of continual advancements in particle physics and consequential changes in the labs direction the group has repeatedly expanded both in capability and size. They have not only continued to provide quality assurance services for the next generation of silicon detectors (CMS Strips and Pixels) but have diversified to providing everything from the design and development of various types of R&D equipment to the preparation of technical reports for R&D activities and inspectional functions. Requests for their services now originate not only from the Collider experiments but from the full gamut of Fermilab experiments and projects; including the astrophysics projects, Neutrino experiments and other R&D projects like the ILC.
