SLS STORAGE RING OPERATION

Several applications, written mainly in Tcl/Tk or Java, have been successfully introduced for the commissioning and operation of the SLS booster and storage rings [3], making ample use of the CORBA framework provided. Server objects were extensively tested through invocations initiated by a variety of client processes. Operator intervention was minimal with clients able to interact spontaneously with the many servers and to display their event data. This is exemplified by the slow global orbit feedback system (3 Hz sampling rate), which is both a consumer to event generated data and a party to remote methods invocations on a variety of servers. A fast version, for which dedicated low-level hardware is to be installed (4 kHz sampling rate), will challenge the reaches of our model [4].
