E. Carlier et al., THE CONTROL-SYSTEM FOR THE LEP BEAM DUMP, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 352(1-2), 1994, pp. 173-175
A beam abort system has been developed and installed in LEP to allow t
he controlled disposal of the stored beam energy. In view of the impor
tance of the system for the protection of the experiments and the mach
ine, and the technical problems in a pulsed high-power environment, sp
ecial care has been taken to arrive at a clean functional separation b
etween the different elements of the control electronics, using optica
l transmission of information. All interlocks have been implemented in
hardware. The slow controls and the monitoring tasks have been realiz
ed in the framework of a modular software tool kit.
