A New Hunting Control Method for Permanent Magnet Hysteresis Motors
Hunting is a flutter associated with the synchronous speed that gives rise to the gyro drifting errors and may cause objectionable time-displacement errors in video head wheel drives and other precision scanning systems. In this paper, dynamic characteristics of permanent Magnet hysteresis motors are presented and hunting is explained. New damping techniques have been developed using optimi...
متن کاملHall Element Relative Position and Angle Calibrations for the Cryogenic Permanent Magnet Undulator
A three dimensions Hall probe has be manufactured for characterizing the magnetic performance of Cryogenic Permanent Magnet Undulator (CPMU) of Chinese High Energy Photon Source (HEPS) at Institute of High Energy Physics (IHEP). The positional and angular misalignment errors of the Hall sensors play an important role in the measurement accuracy of CPMU. In order to minimize the misalignment err...
متن کاملVacuum ultraviolet emission of a permanent magnet undulator on the ACO storage ring in Orsay
2014 We present VUV emission spectra taken on the ACO storage ring from the permanent magnet undulator NOEL (1), currently dedicated to free electron laser experiments, along with an overview at the properties of undulator radiation. The analysis of the spectra includes corrections for the emittance of the electron beam and a small mismatch between the direction of the measurement and the undul...
متن کاملFirst Operational Experience with a Cryogenic Permanent Magnet Undulator at the Esrf
A cryogenically cooled in-vacuum undulator was installed in the ID6 test beamline of the ESRF in January 2008. This 2 metre long hybrid undulator has a period of 18 mm. The magnetic assembly is based on NdFeB permanent magnets cooled at a temperature close to 150 K. A liquid nitrogen closed loop is used for the cooling of the undulator. This cooling system is well adapted to achieve a uniform t...
متن کاملDesign of the Spear 3 Magnet Lattice
The SPEAR 3 Upgrade Project seeks to replace the present 160 nm-rad FODO lattice with an 18 nm-rad double bend achromat (DBA) lattice. The new lattice must conform to the layout of the SPEAR racetrack tunnel and service the existing photon beamlines. Working within these constraints, we designed a lattice with 18 achromatic cells and 3 GeV beam energy. This paper reports on design of the main D...
