The new Tevatron beam position monitor front-end software

The Tevatron is a proton anti-proton accelerator collider operating at the Fermi National Accelerator Laboratory. The machine is currently delivering beams for the CDF and D0 experiments, which expect increasing luminosity until the conclusion of Run II planned for 2009. The Laboratory defined a plan for achieving higher luminosity, and one of the tasks is the upgrade of the accelerator's beam position monitor (BPM). The Tevatron was built during the early eighties and some of its control systems, including the BPMs, are still the original ones. This paper describes the front-end software of the Tevatron BPM upgrade, from the requirements to the implementation, and the underlying hardware setup. The design of the front-end software focuses on its modularity and reusability, allowing it to be applied to other Fermilab machines.
