Dependable Design

  • Critical Function separate (fewer critical circuits)

  • Failure Modes Analysis (weaknesses designed out)

  • Xilinx CPLD used elsewhere (EPC / PIC)

  • 5V and redundant PSU (Highly Available)

  • Mature Electronics (Not risky!)

  • Electro-Magnetic Compatibility (key issue from start)

  • Internally Reviewed 2006

  • External Review in late 2009

  • = robust designreliability and rad tolerance seem linked!

  • -running ½ LHC system in SPS for nearly 4 years 

Motivations for the Tests

The Beam Interlock Controller (x17 in LHC)

-few in surface buildings

-most in zones considered ‘negligible radiation’

-one in control room

-VME Chassis can be moved to surface if ever there is a problem

-any problem will result in safe failure by design

VME is the basis = Not going to Test

The User Interface (x130 in LHC)

-Goes where the User System is “UJxx”

We have to Test

The User Interface Power Supply (x260 in LHC)

-Goes where the User Interface is “UJxx”

We have to Test

Beam Interlocks - Conclusions

  • Critical Path of Beam Interlock System

  • - 8.3 x 10-10 Cross-Section for Glitches = use 1.6us GLITCH FILTER!

  • Good radiation tolerance

  • CPLD failed first at 150Gy – only for MONITORING

  • BUT once we got it back here – reprogrammed it and it worked!

  • Will monitor Glitch counters to indicate potential problems

  • Had plans for RAD HARD CIBU but on hold

  • Needs motivation, time and money! ($)

  • VME is weak? move BICs to ‘surface’ ($$$)

  • Critical Matrix CPLD is same as in CIBU (3.3V variant)

  • VME PSU – redundant!

  • Can research a RAD HARD BIC (not including VME)

  • Needs motivation, time and lots of money ($$$$$)

Plc systems

PLC Systems

Multitude ofPowering Interlock Systemsdeployed in CERN accelerators for protection of nc (WIC) and sc magnets (PIC)

- Installed in LHC, SPS, TI2/TI8, CNGS, LEIR, Booster, Linac,…

- based on a variety of industrial PLCs /IOs and additional electronics

  • Depending on the specific requirements, use of faster SIEMENS 319series or slower (safety) series 300

  • By default, PLCs located in locations considered ‘safe’, generic PLC code

  • Fail safe design, for increased safety most designs incorporate a redundant path using different technology

  • Remote I/O modules collect interlock signals close to clients (magnets, power converters, QPS) and transmit via Profibus to PLC

  • For all components located in / close to radiation environments, dedicated radiation test campaigns conducted to validate

Closing remarks

… Rules of Thumb …

  • Use simple remote logic, keep the complicated electronics away from the radiation

  • Use Fail-Safe everywhere

  • safety systems = redundant signal paths,

  • perhaps less availability = but more dependability

  • Make equipment auto-restarting

  • adequate monitoring/diagnostic tools

  • Implement remote reset (soft vs hard)

  • dedicated radiation tests of critical paths

  • Record batch & lot numbers of critical path devices

  • Use past experience wherever possible = proven components

  • CNGS this year = some new tests

Closing remarks

  • -it was a LOT of effort to get the tests organised

  • -Thanks to Thijs Wijnands / Christophe Martin et al. for all the great work

  • -additional tests won’t need as much effort

  • afterLHC beam commissioning started – we could do some more!

  • If we feel it’s necessary:

  • Optical Transmission Board… (CIBO)

  • Fibre Extended User Interface (CIBFU/CIBFC)

  • VME Equipment (find the weaknesses?)

  • We should plan some beam time next year. NOT a priority for LHC
