  1. Machine Protection System R&D ERLMachine Protection System Zeynep Altinbas February 17-18, 2010

  2. System Overview • The Machine Protection System (MPS) prevents damage to hardware by generating interlocks: • Primarily protects the 50 kW and 1MW RFSystems as well as the 5-cell cavity • Upon fault, an interlock is generated in less than 5 µs • Fail-safe input states • Faults are latched and time-stamped

  3. System Overview of Existing Elements Ethernet Shut-down is performed by Critical Sub-Systems

  4. System Components • Hardware • 8-slot chassis with an integrated RT processor (VxWorks OS) • 2M-gate Xilinx FPGA • 256MB non-volatile memory • Hot-swappable I/O modules with response times as fast as 100ns • CompactRIO chassis: • I/O Module: 11.41″ 3.44″ 2.75″ 3.50″

  5. System Components • CompactRIO Architecture

  6. System Components • Software • Graphic based language: LabView (LV) • CompactRIO requires LV 8.5 or higher & LV RT and FPGA software modules • How the architecture works: • Properties of MPS Software: • High level input = Fault • All faults are latched • Time of fault is recorded using a 32-bit tick counter (µs time-stamp) • Faults are cleared only via a software (user) reset • Inputs can be masked • Communicates with the ERL main server

  7. Existing System • MPS for Cold Emission Test (CET) • 3 I/O modules (TTL, 24V and Relay) • 9 Sub-system inputs, 5 outputs • MPS interface on C-AD Controls page • Critical sub-system status is displayed • System response time = ~3-4 µs • All operating features are tested successfully

  8. Summary • Protects the 50 kW & 1 MW RF Systems and the 5-cell cavity • Uses a commercial development platform produced by National Instruments • Can run as a stand-alone unit (no network connection is necessary to run) • Provides expandability • Response time on a microsecond scale (~ 3-4 µs)
