Issues last 10 years BWS Breaking wires due to: - Beam interaction. - Induced RF power. Instabilities of position and profile measurements due to: - Inaccuracy of position measurements. - Flexibility, vibrations in mechanics and wire (in some cases). Aging bellows in PS (broke after ~13000 scans). Outgassing bellows in LHC during bake-out. Timing jitter in PS. Magnet quenching in LHC (simulations GEANT4). Fixation wires in fork.

2) The aim of the project is to change 3 different types of scanner by only one that will have better performance in terms of accuracy, reliability, speed and acquisition dynamic range. SPS BI Day 2017 P.Andersson

The motor is changed from a DC motor to a permanent magnet brushless synchronous motor. Which will demand new electronics. Courtesy of D. Gudkov New Mechnics, Encoder and Fork on the Motor axel! Less mechanically Play! BI Day 2017 P.Andersson
