Faults Detection on the LHC Beam Dump Kicker System

This report describes a proposal for fault detection on the LHC beam dump kicker system. As a result of a fault analysis two fault detection modules are proposed; A off-line test and a continuous surveillance. The fault detection, needing continues data, and the requirements to the data acquisition is given special attention. The off-line test declares the system, including stand-by components, fault tree prior to beam injection. the test comprises parameter estimation using the sensitivity approach requiring an ADC with better than 7 bit precision and a sampling frequency above 133kHz. The continuous surveillance comprises a model based fault detection method, based on analytical redundancy. The system requirements are a 14 bit DAC and an 16 bit ADC with a sample frequency above 1.54Hz.
