Title: Non-invasive Beam Monitor, Fast Kicker, Bunch Shaper, and Photogun

Abstract

The DOE’s SBIR program has catapulted a simple idea, into a working tool for continuous non-invasive bunch length monitoring. A harmonically resonant cavity, designed and constructed in this program, is installed within the CEBAF injector, and as a result, a machine operator in the control room can view, in real time, the longitudinal shape and duration of electron bunches as they are created, with picosecond accuracy. This effort has also resulted in two scientific publications, the 2016 International Beam Instrumentation Conference’s Faraday Cup Award, and awarded two US patents. The Phase I title of this project was simply “Non-Invasive Bunch Length Monitor” but expanded in Phase II to include “Fast Kicker, Bunch Shaper, and Photogun”. Phase II activities included optimizing the design and fabrication of harmonic cavities for beam monitoring, and the developments of high power harmonic driver electronics to pursue active applications of harmonic cavities. The design and fabrication optimization resulted in doubling the harmonic cavities bandwidth in a more reliable and manufacturable design. The development of high power harmonic drive circuits and controls has demonstrated the feasibility of driving harmonic cavities for a multitude of applications including bunch shaping, fast kicking, and for pulsed charged particle sources.
