Operation of the Central Trigger During Run-I
- 281 Downloads
As described in Sect. 7.6.3, the Central Trigger receives the timing signals from the LHC and is responsible for their distribution through the experiment. Any shift, glitch or misalignment of the timing signals will lead to a loss of data, since for example the event fragments cannot be assembled correctly anymore. In this sense, the CTP constitutes a single point of failure, and a detailed monitoring of the timing signals is essential for an effective data taking and good quality data.
