Phys. Rev. ST Accel. Beams 12, 012801 (2009) [8 pages]Measuring transverse beam emittance using a 2.07 GHz movable Schottky cavity at the Relativistic Heavy Ion Collider
Using a movable Schottky cavity resonant at 2.07 GHz, we have developed a simple method of deriving the beam sizes at the detector. In this report we will explain the theory behind the method, describe the system and the signal processing, and then present the results from experiments using this method. We will also present our plans for using this new technique for obtaining beam emittances during normal operation of the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory (BNL).
