The BLMs are protecting various machine elements against beam losses. The beam-abort thresholds have been computed differently depending on type of protected element. For cold magnets the methods of thresholds computation are described in [12,13,14]. In case of collimators the relevant document is [15] and in case of warm magnets the present strategy is documented in [16,19].
Two aspects of threshold correctness are discussed here:
The major modification to cold magnet thresholds, which has been done before 2011 run, is presented.
