Abstract

The highest priority in the Nuclear Physics program is, at present, the Facility for Rare Isotope Beams. In the longer term it is likely that a high priority will be an Electron Ion Collider, and several concepts are under development. In order to achieve the high luminosities that would be required to make such a machine attractive, some kind of bunch crabbing system will be required. For example, the Electron Ion Collider under study at Jefferson Lab would require a crabbing voltage between 20 and 50 MV at either 499 or 1497 MHz. RF crabbing systems are important components in linear colliders where the beams meet at an angle. A crabbing system rotates the bunches at the collision point so they meet head-on, instead of crossing at an angle, thus restoring and increasing the luminosity. The requirements for a crabbing system for an Electron Ion Collider, as envisaged at Jefferson Lab, are quite stringent, exceeding what has been accomplished so far. A crabbing system could, in principle, be built using room temperature cavities. However, in order to produce the needed voltage a large number of cavities and their associated rf power system would be required. An attractive alternative solution would be based on a superconducting cavity of a new design that has been introduced recently. This new design, if optimized for this application, could provide the required deflecting voltage in a footprint that would be compatible with the design of the interaction regions. Commercial Applications and Other Benefits: This STTR research would continue ODU, JLab, and Niowave
