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 کاملTuning and characterization of Twente wiggler
For correcting field errors in the Twente wiggler small metal shims were placed on the pole faces. When applied to correct errors in the on-axis field a large increase in the errors in the off-axis field was found. When instead errors in the off-axis field are corrected, the errors in the on-axis field are reduced as well. Only small corrections were locally required to make the errors in the o...
متن کاملLessons from the 3-pole Sc Wiggler Test
In a framework of a CESR upgrade to Charm-Factory [1], there was proposed to install wigglers for obtaining the damping required. Such a wiggler unit supposed to be short enough allowing modular filling of the ring’s free space [2]. As the full-scale wiggler model is a long-time enterprise, it was suggested, that 3-pole model can be manufactured quickly and all nuances of technology and enginee...
متن کاملField Measurements of the Kek B-factory Dipole and Wiggler Magnets
The KEK B-Factory (KEKB) [1] consists of 3.5 GeV positron (LER) and 8.0 GeV electron (HER) rings and has more than 290 dipole and 150 wiggler magnets. Both the LER and the HER use four types of dipole magnets. Wiggler magnets are used for the LER. Three long flipflop coil systems were used to measure the transverse distribution of the integrated magnetic field along the beam direction. Each dip...
متن کاملThe Stanford Synchrotron Radiation Laboratory - 20 Years of Synchrotron Light-
The Stanford Synchrotron Radiation Laboratory (SSRL) is now operating as a fully dedicated light source with low emittance electron optics, delivering high brightness photon beams to 25 experimental stations six to seven months per year. On October 1,1993 SSRL became a Division of the Stanford Linear Accelerator Center, rather than an Independent Laboratory -of Stanford University, so that high...
