Abstract

After approval of the construction of the new separated function electron synchrotron, DESY II, in May 1983, the design and fabrication of all components was completed and the new machine fully installed during a four month winter shutdown from Nov. 84 until Feb. 85. The new machine will be tested in parallel with normal operation of the old 7 GeV synchrotron, DESY I, by using 200 MeV electrons injected from the upgraded Linac I. Provisional power supplies run the magnets up to 1 GeV. During a second shutdown in winter 85/86 it is planned to install full magnetand rf-power and to connect all beam transfer lines to PETRA and DORIS. DESY I will then be turned off and most of the components will be used to form a new proton synchrotron (DESY III) for the HERA e--p project. An updated parameter list and first results from the initial tests of DESY II will be presented.
