The ANKA injector

Abstract

ANKA is a 2.5 GeV synchrotron radiation storage ring under construction at the Forschungszentrum Karlsruhe in Germany. The beam is accelerated up to 0.5 GeV in a booster synchrotron and afterwards injected into ANKA. In ANKA the beam is accumulated to 200 mA (second stage: 400 mA) and afterwards accelerated to 2.5 GeV. The injector system will consist of a pre-injector with an end energy of 20 or 50 MeV, a booster synchrotron and transport channels. The booster synchrotron should be as simple and inexpensive as possible. In the following three different concepts for designing the booster synchrotron are compared.
