  1. Instrument Readiness Review at NSLS II 2018 Accelerator Safety Workshop; SLAC Andrew Ackerman NSLS II ESH August, 2018

  2. Outline • Instruments (Beamlines) • Instrument Readiness Review process • Experience

  3. Instruments 3

  4. NSLS II • Accelerator Ready Review • ARRs • (FY14) • Commissioning: linac, booster, storage ring • Routine Ops • User Science

  5. NSLS II Beamline (An Instrument)Integrated In-situ and Resonant Hard X-ray Studies (ISR) • ISR In Vacuum Undulator (IVU-23); long straight IVU-23 HFM 3 endstations DCM SSA DPP VFM DHRM KB

  8. Beamline Hazard Analysis • Standard accelerator risks: • Electrical power • Fire • Pressure safety • Cryogens (LN2 & LHe) • Lead • Radiation • Bremsstrahlung – primary (ray trace) & secondary (Fluka); High energy, low power • Synchrotron – secondary (STAC 8); heat load (equipment & shield protection); low energy, high power

  9. IRR Process 9

  10. NSLS IIBeamline Instrument Readiness • Readiness “Systems and procedures established to address credited controls, documentation requirements, and personnel qualification“ ―Accelerator Safety Order • Ready to commission • Technical • Safe photon beam generation and delivery into the experiment endstation. • Science • Optimize performance • ‘Friendly’ Users • Beamline Instrument Readiness Review (IRR) – Technical Commissioning start • Point in time; Scope definition important Ready for User operations – separate process; procedure: review system • Beamline space – annual review; BNL electronic system • User science – beam time cycle review; another BNL electronic system

  11. Building a BeamlineAn Extended Project (years) • Design & Plan • Science • Hazard control • Procure • Install • Travelers – checklists – meet specs • Integrated testing (no beam) • Assign and qualify staff • Role • Procedures • Instrument Readiness Review • ~ 6 weeks Getting Ready • Instrument Readiness Plan • Organize • Define: • Scope • Basis • System specific • Actions & documents • ~40 criteria • Status tracking • Declare ready – signatures • Lines of Inquiry (LOI) for the review IRP

  12. Instrument Readiness Plan (IRP) CriteriaDesign and Plan • Functional description (scope definition) • Design • Source, Front End, & Beamline components • Radiation Safety components • Top-Off Safety System (TOSS) • Bremsstrahlung & Synchrotron Ray traces • Secondary radiation scatter analysis (FLUKA & STAC 8) • Plan • NEPA evaluation • Un-reviewed Safety Issue (USI) resolution • Legacy open action item resolution • Instrument specific procedures • Commissioning plan • Radiation survey plan

  13. Instrument Readiness Plan (IRP) CriteriaInstall and test • Radiation safety components • Shielding, masks, labyrinths, shutters … • Area Radiation Monitors (ARMs) • Personnel Protection System (PPS) interlocks • O2 Sensors • Hutch structures (life safety) • Electrical power distribution • Utilities (water, LN2, LHe) • Beam transport components • Equipment Protection System (EPS) • Controls • Vacuum Safety Critical Other

  14. Instrument Readiness Plan (IRP) CriteriaAssign and qualify staff • Assign roles and Job Training Assessments • Lead Beamline Scientist • Authorized Beamline Staff • Cognizant Space Manager • Beamline Support Staff • Assign procedure training • Read and sign • Demonstration

  15. Review Team Charge • 7 person team – BNL & NSLS II • Web page • Team collects information: • Interview staff • Read documents • Inspect the instrument • Team provides: • Review details (staff, document, topics) • Observations (noteworthy practices; suggested improvements) • Findings (pre & post) (tracked to closure) • “Recommended” Corrective Actions Pre-start means (Required for safe beam operation)

  21. ExperienceNSLS II Beamline IRR The IRR is a big effort (Beamline and Accelerator staff) • Intended • Significant risks (personnel and project) • $10 – 15M instrument • High expectations – Users are coming • NOT an agile process – 6 to 8 weeks preparation • Weekly status meetings (needed, but not popular) ~ 45 managers / engineers / scientists • Varied documents to complete, file, and post on web (some) • ~ 40 criteria – signatures • Report and follow up

  22. ExperienceNSLS II Beamline IRR It is hard to be ready on time • Must schedule a date in advance – deadline • Project deliverables / milestones • Best = source to end-station • In practice – Source & FE ready first – split into two IRRs • Science wants review once something is ready (adjust scope) • Biggest challenges • Vendor supplied items • Lead shielding components • Optics • PPS design / installation • Radiation safety analysis (ray traces and scatter) • All documentation (one week in advance) • Ray traces • Final layout capturing all radiation safety components • Mechanical survey reports • Discrepancy reports • Adjust scope to meet date: something is ready • Self-identified pre-start – we’re almost ready

  23. ExperienceNSLS II IRR Readiness brings resources that leave after the review. Strategy • Clear IRP criteria definition = difficult; important • Multiple instruments reviewed together = stress installation resources • Review team selection • NSLS II / BNL • BNL SMEs; NSLS II scientist, ESH, QA • Added BNL review team leader (2017); new eyes and perspective • PPS, EPS, Controls – unique for reviewers • Review meeting time? ~ 1.5 days / instrument • Walkthrough is productive – seeing stimulates conversation • Tailored Review Plan: • IRR threshold? Equipment Readiness Review (ERR)?

  24. ExperienceNSLS II Beamline IRR Findings • Configuration control • Labeling, photos, checklist • Utility mechanical support and labeling • Bump and trip hazards • Documentation for pressure testing. Utilities, windows (Kapton, diamond, Be) • Hutch Personnel Protection System (PPS) hardware field location • Forced search buttons locations & emergency stops • Installation sequence forces early decisions
