Data flow: Main operation: From operation mode program via file operators to file operator servers

1. Injection from Linac-2 to Desy Archivation Desy-2 Archivation Linac-2 / PIA The PC Control System for Linac-2, PIA and Desy-2 W.Gerhardt, U.Glöer, K.Hinsch, G.Mann, F.Wedtstein, Desy Hamburg Operation Mode LINAC-2 / PIA DESY-2 450 MeV linear accelerator for electrons and positrons with the intensity accumulator PIA and beam-pass L-Weg injector for the synchrotron Desy-2 7 GeV synchrotron for electrons and positrons, preaccelerator for the storage rings Doris (source for synchrotron radiation for Hasylab) and Petra (preaccelerator for Hera e- / e+ , source for synchrotron radiation for Hasylab ) Automatic operation Automatic operation Machine Operation Mode Program With the operation Mode Program it is possible to switch the three accelerators to the machine modes: Doris e+, Petra e- and Petra e+. All machine device groups are simultaneously prepared for the new mode by the file operator of Linac-2 and Desy-2. To synchronize the machines the cycle generator is loaded with a new machine program.
