Abstract

A new scheme of beam extraction from a synchrotron is put forward. The main difference from other schemes of extraction is the use of magnetic shields instead of a septum. The magnetic shields are located in the central dipole magnets of a pulsed chicane. A magnetic shield is a multi-layer copper-iron tube. The presented numerical simulations and experimental results for the magnetic shields are in good agreement. The advantages and the area of application of the new extraction scheme are discussed. The proposed scheme will be used for extraction from the booster synchrotron to the storage ring of the new synchrotron radiation source in Novosibirsk.
