As mentioned the MSS is a common project. For this purpose a series of signal conditioner and logic As mentioned the MSS is a common project. For this purpose a series of signal conditioner and logic modules has been developed and tested, identical for all experiments. Due to severe modules has been developed and tested, identical for all experiments. Due to severe restrictions regarding high tension, galvanic isolation, features and lifetime, no commercial restrictions regarding high tension, galvanic isolation, features and lifetime, no commercial components are available for this.components are available for this.
These modules will be used for safety systems in all LHC experimental magnets.These modules will be used for safety systems in all LHC experimental magnets.
To accommodate the modules, a complete chassis system has also been developed, which will be To accommodate the modules, a complete chassis system has also been developed, which will be common for both analogue and digital modules. It will consist of a standardized chassis, a common for both analogue and digital modules. It will consist of a standardized chassis, a monitoring module, and redundant power supplies. Each chassis will be connected to a monitoring module, and redundant power supplies. Each chassis will be connected to a centralized alarm system via a monitoring module. Together with the separate ventilator unit, centralized alarm system via a monitoring module. Together with the separate ventilator unit, this will be the basis of all MSS systems.this will be the basis of all MSS systems.
