Simultaneous Position Measurements of Protons and Anti-Protons in the Tevatron

Fermilab is nearing completion of an upgrade to the electronics of the Beam Position Monitor (BPM) system that measures the transverse position of the beams inside the Tevatron collider. A new feature in the upgraded system is the ability, when both protons and anti-protons are present in the Tevatron, to make simultaneous measurements of the closed orbit position of both beam species. This paper will present one of the methods for achieving the simultaneous measurement and will present results from commissioning data, which demonstrate that the system achieves its requirements.
