High Sensitivity Beam Position Monitors for 1300 MHz Croyomodules

The proposed International Linear Collider will require a high-accuracy beam position monitor (BPM) at each quadrupole magnet to aid with beam alignment and as an input to feed forward schemes to cancel alignment errors. In order to meet the requirements of ILC, the BPMs will require sub-micron position resolution, fast transient response, and a relatively large clear aperture of 70 mm. Fermilab's Project X also has a need for similar hardware. FAR-TECH, Inc. proposes a variation to existing schemes which gives roughly 30% greater shunt impedance, while meeting all other ILC requirements. The BPM, including the coupling method and diagnostic electronics will be designed using computer modeling, developed, prototyped and tested. Commercial Applications and Other Benefits: The International Linear Collider promises to shed new light on fundamental processes at the highest energy collision scales, and complement the physics program at the Large Hadron Collider. Sub-micron beam position measurements are crucial to beam emittance preservation and control in this machine. FAR-TECH, Inc. hopes to commercialize the BPM design and create one additional source of BPM systems for the eventual construction of the ILC and other high energy and nuclear physics applications
