Magnetic and electrostatic deflecting devices

A short description is given of a number of deflecting devices in use at CERN, with emphasis on some of their technological aspects. In particular, the cyclotron magnet, the Split-Field Magnet at the ISR, and the magnet of the 2 m Liquid-Hydrogen Bubble Chamber are discussed, as well as the magnets of the synchrotron lattices of the Proton Synchrotron, Intersecting Storage Rings, and Super Proton Synchrotron. In addition, some remarks are made on the technology of septum magnets and fast pulsed magnets. Finally, the application and the technology of electrostatic separators and electrostatic septa are described.
