n a trip to the CMS detector at CERN this month, Fermilab’s Greg Derylo, Burt Gonzalez and Wanda Newby performed delicate surgery on the CMS forward pixel detector to replace some pixel modules requiring maintenance. The FPix is used for precision particle tracking and mounts directly around the beam pipe in the heart of the detector. It was built at Fermilab’s SiDet facility and has been temporarily removed while shutdown work at CMS is being performed.
