Magnetic counterforce for insertion devices.
In a standard insertion device, such as a wiggler or undulator, the force between two rows of magnets increases exponentially as the gap between the rows decreases. This force is usually managed by a powerful mechanical gap adjustor, sometimes with the aid of springs at small values of gap. This paper is a description of how the magnetic forces can be nulled using auxiliary counterforce magnets.
متن کاملMagnetic Performance of Insertion Devices at the Advanced Photon Source
The insertion devices (IDs) at the Advanced Photon Source have been magnetically tuned to minimize the integrals of the field through the devices and to minimize the variation of those integrals with gap, with a goal of not perturbing the stored particle beam. Measurements of the particle beam motion as the ID gap was changed found that the closed-orbit distortion was better than the requiremen...
متن کاملChamber Motion Measurements at the Nsls X-ray Ring
Work has been ongoing at the NSLS to improve the orbit stability of the X-Ray Ring by accounting for the thermal motion of the vacuum chamber, which supports the electron beam position monitors (BPMs). In-situ contact measurements of the vacuum chamber motion have been carried out using support stands that have been designed and extensively tested to reduce errors associated with thermal change...
متن کاملCoherent Radiation Measurements at the Nsls Source Development Lab*
The far-infrared coherent emission from short electron bunches has been detected and partially characterized for two source locations at the NSLS Source Development Lab (SDL) accelerator system. One location is designed to extract dipole edge radiation while the other extracts transition radiation produced a short distance downstream of the SDL linac. The coherently radiated energy per pulse is...
متن کاملInsertion Devices
The characteristics of the synchrotron radiation generated by an electron beam in bending magnets, planar undulators and wiggler magnets are derived, with emphasis on the spectral flux, brilliance, and power densities. The interaction of the electron beam with the insertion device field is discussed in terms of closed orbit distortion, tune shift and non-linear effect. The technology of permane...
