PH/DT MCP & MNO
Commitment:
- To assure the availability of Atlas, CMS, Alice and LHCb magnets.
- To assure the preventive and corrective maintenance of the experiment magnets.
- Magnet ON-Call Standby service 24/24 h, 7/7 d, 365/365 y
- When beam is ON, we provide support for other magnet control and systems related to control and instrumentation

MSS – MAGNET SAFETY SYSTEM
The purpose of the MSS is to detect anomalies endangering the safety of the magnet and to take appropriate action in order to bring the magnet into a safe state. • Maximum availability/reliability• Dedicated sensors• Multiple detection techniques/Overlapping sensors• Redundancy• Galvanic Isolation• Fail-safe operation

Why upgrade? Mean Time Before Failure - Components
• Worst case calculations - Environmental factors• Many opto-couplers (in series)• Some components no longer available – Isolation amplifier – FPGA• MSS started in 1998 – First installation 2002-2003 (CS of ATLAS – Still running)
