8 TE/MPE/MI - CERN Machine Interlocks 8 of 43 Dependable Design 1.Critical Function separate (fewer critical circuits) 2.Failure Modes Analysis (weaknesses designed out) 3.Xilinx CPLD used elsewhere (EPC / PIC) 4.5V and redundant PSU (Highly Available) 5.Mature Electronics (Not risky!) 6.Electro-Magnetic Compatibility (key issue from start) 7.Internally Reviewed External Review in late 2009 = robust design reliability and rad tolerance seem linked! -running ½ LHC system in SPS for nearly 4 years

9 TE/MPE/MI - CERN Machine Interlocks 9 of 43 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

45 TE/MPE/MI - CERN Machine Interlocks 45 of 43 Closing remarks “Better the devil you know” … 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
