Survey of the A, B and C layers of the Fermilab D0 muon detector system
The Fermilab D0 detector is currently being upgraded to exploit the physics potential to be presented by the Main Injector and the Tevatron Collider during Run II in the Fall of 2000. One of the essential elements of this upgrade is the upgrade of the Muon detector system. The Muon detector system consists of the Central Muon Detector and the Forward Muon Detector. The Central Muon Detector consists of three detector systems: the Proportional Drift Tube (PDT) chambers which were used in Run I, the B- and C-layer Scintillation Counters, and new the A-layer Scintillation Counters. The Forward Muon Detector consists of the Mini-Drift Tubes (MDTs) and the Scintillation Pixel Counters. There are three layers, designated A, B, C, of the Muon detector system. The A-layer is closest to the interaction region and a toroid magnet is located between the A- and B-layers. This paper discusses the methods currently employed to survey and align these PDTs, MDTs, and the scintillation pixel counters in the three layers of the Muon detector system within the specified accuracy. The accuracy for the MDTs and PDTs is {+-}0.5 mm, and {+-}2.0 mm for the scintillation pixel counters. The Laser Tracker, the BETS, and the V-STARS systems are the major instruments used for the survey.
