“…A radio frequency cavity with resonant frequency near a harmonic of the fundamental rf cavity may increase Landau damping of synchrotron oscillations and lengthen the bunch, thereby suppressing coupled-bunch instabilities and increasing the Touschek lifetime [1][2][3][4][5][6][7][8][9]. A Landau cavity may be operated in passive mode, where its voltage is induced by the beam current, or active mode, where its voltage is maintained by an rf power supply and feedback.…”

A radio frequency system with a fourth-harmonic "Landau" cavity suppresses coupled-bunch instabilities and increases the beam lifetime of the Aladdin electron storage ring. When the storage ring is operated with a small momentum compaction, instabilities limit the utility of the Landau cavity. Analytical modeling of instability frequencies and growth rates, simulations, and experiments suggest that the observed instabilities result from coupling between dipole and quadrupole Robinson modes.

“…Crossed slits may also be used in place of a pinhole; A crossed-slit beam diagnostic is currently under test at the Brookhaven National Light Source. (5) High aspect Au pinholes 50.pm in diameter and several inches long for neutron pinhole imaging have been produced at Los Alamos National Laboratory by plating Au on Cu wire .and acid etching away the wire mandrel( lo). It is difficult to obtain round wires with diameters on the order of 10 p m for.use as mandrels, but some manufactures will supply short lengths suitable for pinhole fabrication.…”
