SM2 control synoptique

The contol system is managed by an old SPS Main Bends electonics for the interlocks, an old SPS Aux PS electronics for the regulation and a converter crate modified from the North area.

The bending magnets B4 and B5 of M2 beam line needs to be interlocked with SM1 and SM2 spectrometers. To manage this functionality, the power converters of B4, B5, SM1 and SM2 are interconnected.
