Compensation Scheme of Elliptical Polarization from Bending Magnet at SRRC
نویسندگان
چکیده
A prototype elliptical polarization from bending magnet ( EPBM) system with a dynamic local bump has been implemented at the SRRC storage ring. The local bump is created by using two pairs of vertical correctors located on each side of the bending. The bump strength coeffieient was obtained from measured beam response matrix. Disurbance of stored electron beam orbit was boserved while flipping the corrector polarity during EPBM operation. It was determined that beam orbit disturbance was caused by bump phase mismatch among bumper magnets. Measured result of this phase mismatch among bumper magnets. Measured result of this phase mismatch and its compensation by using wavefrom generator is presented in this report.

Passive End Pole Compensation Scheme for a 1.8 Tesla Wiggler
An optimized end pole compensation scheme for the 1.8 Tesla, 25-pole wiggler W20/SRRC was studied by using 2D magnetostatic code OPERA-2d. The maximum deviation of the dipole steering for this wiggler can be minimized either by optimizing the sizes of the bias magnets or by optimizing the easy-axis rotating angles of the permanent rotators. After optimization, the dipole steering is within 100 ...
متن کاملIntegral Dipole Field Calibration of the SRRC Storage Ring Combined Function Bending Magnets
Due to the presence of fringe ®eld on both magnet edges, the real trajectory traced out by the beam will deviate from expectation. The integral dipole strength seen by the beam will then have a discrepancy to design value. The beam tracing method is employed to correct fringe ®eld effect and to calibrate integral dipole strength of the bending magnets by tuning magnet current. Final correction ...
متن کاملPolarization-modulated magnetic soft-x-ray transmission microscopy
An adjustable aperture element has been integrated into the full-field soft-x-ray microscope at the Advanced Light Source to select either the right or left elliptically polarized x rays emitted at an inclined angle from a bending magnet. Magnetic contrast recorded at the Fe L3 edge in a 59-nm-thin Gd25Fe75 layer can be modulated and scales with the degree of circular polarization in agreement ...
متن کاملThe Upgrade of Srrc Booster Extraction System
It is planned to upgrade the SRRC booster from 1.3 GeV to 1.5 GeV for full energy injection into the storage ring before the end of 1999. Based on the technical specification and operation experience, it is concluded that some of the subsystem components need to be rebuilt, such as the magnet power supply systems and beam extraction elements. A review of the power supply system will be reported...
متن کاملFerroelectric polarization flop in a frustrated magnet MnWO4 induced by magnetic fields
The relationship between magnetic order and ferroelectric properties has been investigated for MnWO4 with long-wavelength magnetic structure. Spontaneous electric polarization is observed in an elliptical spiral spin phase. The magnetic-field dependence of electric polarization indicates that the noncollinear spin configuration plays a key role for the appearance of ferroelectric phase. An elec...
