WIC (Warm magnet Interlock Controller) layout Standardized interlock system for normal conducting magnets based on PLC: Collects inputs from thermo-switches, flow switches and internal PC faults Then gives the Power Permit to the power converter No Beam Dump at HIE-ISOLDE

The program running in the WIC is extremely simple WIC principle The Warm magnet Interlock Controller is a PLC based system, using deported I/O crates (connected via Profibus). The Siemens “F” (F stands for Fail safe) Series PLC is used, offering a self checking safety environment and programming through ‘Safety Matrix’. We use generic SW and (to some extent) HW for all our installation, to allow for efficient and resource optimized installation, commissioning and operation. The program running in the WIC is extremely simple IF (Magnet Overheats) OR (Flow Switch opens) THEN [According to the Configuration file] Switch-off the relevant PC(s) IF (Magnet Overheats) OR (Flow Switch opens) OR (PC Status failure)THEN [According to the Configuration file] send Beam Dump signal

WIC design for HIE-ISOLDE HIE-ISOLDE will be built in 3 stages The hardware (PLCs + Patch panels) is designed to cover the 3 phases 1st WIC to protect REX-ISOLDE + XT00 line 2nd WIC to protect XT01, XT02, XT03 experimental lines All control cables (Magnets + PCs) are already pulled for the 3 stages Modification between phases managed by software only: Will involved a full re-commissioning at each stage. Number of elements to connect: Existing (Rex-Isolde): Existing power converters 1 dipole 1 20 quadrupoles 1 steerer (H/V) 2   New magnets New Power converters 7 dipoles 7 (S500) 32 quadrupoles 34 (Cobalt) 23 steerers (H/V) 53 (Cancun)

How it looks like in real… XT03 line XT02 line Tunnel XT01 line completed Platform with WIC n°1+ PCs WIC n°2 2 quads + 1 steerer

Modification of the software part First version of the generic code (for safety PLCs) was written for the LHC Experiences in the SPS and the Booster showed the need for more flexibility Decouple the Beam Dump and Fast Abort signal generation Reduce our dependence on BE/CO Before: WIC projects data not entered directly by us in a private DB  Not linked to Layout DB  Before: SQL scripts depending on CO support and difficult to maintain for the generation of config. files  ECR 1360777 circulated to explain the reasons for the changes & impact on each machine & mitigations plans: LHC, SPS, Linac 4, LEIR, Linac 3

The software part (2/2) HIE-ISOLDE project: Guinea pig to test: Major changes in the generic code of the PLC New process of generation of config. files for the PLC and WinCC software WinCC config file PLC config file Controls Configuration Database Magnet 1 E1.1 … PC Status 1 E3.1 PC Mask Beam Dump Card 1 EB12-14 Card 2 EB16-18 Card 20 EB62-64 Magnet + PC Status + Pow Failure Hardware configuration WIC Editor -> APEX interface Fast Abort PLC generic code: - 2 independent matrices - Increase of size of the matrices 11x -> 12x 8 DO modules WinCC generic code New «Lock» feature New color code (orange = passivation) Adapt to the modifications in the PLC code Java scripts Data recorded in Controls DB First use of java scripts to generate config files First use of WIC editor 5 months of thorough & iterative tests with EN/ICE Transition very well prepared well ahead of time by Ivan (with BE/CO) to define the DB structure, the WIC Editor and writing the Java scripts

Documentation Work Package Description (WPD) approved on EDMS Second version in preparation Commissioning procedure was co-written between the main stakeholders MPE, EPC and MSC A SharePoint website was put in place for the follow-up of the commissioning steps for each circuit.

Future project? Studies on-going to build a storage ring (TSR) New building for TSR machine : 670 33.27 m 26 m Building 508 B 170

Conclusions I was involved at a very early stage in the project Numerous advantages: Apply LHC standards, optimization of (cabling) costs, rack reservation, cable pulling secured, integration of our interlock boxes etc... Drawback: Many iterations of the layout design. All deliverables installed in February 2015… on time for the HWC Very high motivation in the teams involved in the project (# renovation project) Coordination and installation went smoothly Several issues found on the ‘old’ Rex-Isolde magnets: Responsibility of MSC. Phase 1 of the project will be finished (for us) by end of June 2015 Physics foreseen for October 2015 

Interlock boxes Interlock boxes are placed on or close to each magnet to collect all input signals. For maintenance purpose, a remote test feature is implemented (by means of a relay) in order to simulate the opening of any input signal. This operation can be done remotely and allow us to check periodically the installation during shutdowns.

Type of Interlock boxes used at HIE-ISOLDE 1-channel - Interlock Box: Dipoles, Quads 1x Thermo-switch + 1x Remote test 2-channels - Interlock Box: Steerers (H/V) 2x Thermo-switches + 2x Remote test 4-channels - Interlock Box: Triplets, Doublet 3x Thermo-switches + 1x Flow switch + 4x Remote test New design for Hie-Isolde
