PH-DT/DI Section Focus
• Construction of detector and experiment infrastructures and dedicated M&O services
(e.g. on-call)
• Development to ensure that infrastructures perform and are technologically up to date
• Contribution to shorter term projects (pilot projects to validate larger developments)

B-field measurements
Magnet Related Activities in PH-DT
• The Magnet Control Project (MCP) was initiated in 1998 with the goal of
producing an integrated system for controlling, protecting and analyzing data
for the large magnets in the LHC experiments. Common hardware and
software have been designed to facilitate the maintenance and operation.
– Today’s Mandate: Preventive and corrective maintenance of MCP systems, OnCall interventions, planning of maintenance tasks during shutdowns.
Maintenance of the control software and implementation of PVSS modifications
as requested by main users.
•
The B-field measurements service provides technical support for magnetic field
measurements and calculations, and develops new sensors, readout applications and
data analysis techniques for this activity.
•
The group has a considerable level of technical expertise in constructing magnets,
however due to retirements and transfer of staff it has lost the design and
engineering capabilities.
MCP Team
• Currently the MCP team is composed of a project leader
and fractions of DT technical staff, who contribute to other
projects in DT

80% Project leader
50% Tech as CMS and LHCb expert, and responsible of MCP On-Call Service
50% Tech as ALICE expert
80% Tech as ATLAS expert
50% Controls engineer
• The team runs an On-Call service 24/7, assisted by DSS and
magnet experts from the LHC experiments.
• 4 FTE from the PH-02 Field Support Unit are dedicated in
average to the project

Hands-on electronics review

MCP is run by a small team in charge the maintenance and operation of the control and safety
systems of the experimental magnets installed in 4 LHC experiments
These control and safety systems were developed by the team more than a decade ago; they are
based in standard and industrial controls and instrumentation, like PLC logic for the control and
FPGA for safety. These systems include some electronic development, mainly related to the
magnet safety system for superconducting magnet quench detection.
The current systems has been working fine during the LHC operation, however they start to be
rather old, some electronic components are obsolete, and new control & instrumentation
technologies offer more possibilities.
An upgraded system is now being developed in PH-DT, which includes the electronic interface for
the quench detection and temperature measurements. A prototype is currently in production,
based on team’s experience and also technology transfer between CERN experts.
Small magnets (M1 and Compass) will be equipped with the upgraded safety systems in 2013.
Based on the operational experience in these 2 projects, the new system will be proposed to the
LHC experiments (if possible, still during LS1)
The aim of this review is to get a second opinion on the electronics aspects of the new MSS2
system from 'outside' electronic experts in order to validate the prototype system and to be
able move to the next project phase (construction of systems for LHC).
to all the MCP team,
and the reviewer(s)!
