SST Beamline Infrastructure Scope
WBS 7.02.04 - Beamline Infrastructure (C. Stebbins)7.02.04.01 –Hutch (E. Haas)7.02.04.02 – Mechanical Utilities (J. Gosman)7.02.04.03 – Electrical Utilities (G. Ganetis)7.02.04.04 – EPS (R. Kadyrov
)
7.02.04.05 – PPS (G. Fries)
Same CAM structure is applied across other beamline projects at NSLS-II
Ensures coordination of resources and scheduling
Streamlines communication and points of contact
Better application of lessons learnedSlide4
Beamline Infrastructure Technical Team
The infrastructure technical team will be supported by existing fully staffed groups Matrixed Organization employed to execute scope:NSLS-II staffing, including Engineers, Designers, and TechniciansTrades (Electricians, Plumbers, Riggers, etc)Outside Contractors (LN2 Piping, experimental exhaust)Personnel already experienced with Beamline Common Systems (i.e. NSLS-II Project Beamlines, NEXT, ABBIX, and other NSLS-II Partners).Able to leverage “standard” designs from existing beamline systems.Able to value engineer existing systems.Able to bundle procurements of common parts across projects to reduce costs.Slide5
SST Hutch OverviewSST has a first optical enclosure (FOE):Hutch design review was previously held in 2014. Includes lead shielding. Labyrinths located overhead to accommodate utilities and cables. Labyrinths located on outboard hutch wall for PPS conduit and user needs, as well as hutch ventilation.Automated door actuation.Access/egress via stairs to storage ring mezzanine.Foot bridge installed for access/egress to adjacent 6-BM-B hutch (BMM)
Overhead mobile hutch crane with 1 ton capacity
Was manufactured and installed by
Caratelli
in
2014, as part of NEXT lead hutch procurement.
All acceptance testing is
completedSlide6
SST Mechanical Utilities OverviewTechnical ScopeStandard utilities installation scope that has been used at other NSLS-II beamlines, and tailored to needs at SST. SST scope is larger than a typical beamline due to multiple end stations and number of critical safety components that require cooling.De-Ionized (DI) Water, from Accelerator for cooling beamline components on beamline.4 circuits for cooling PPS components13 circuits for cooling EPS componentsProcess Chilled Water for cooling equipment racks and user / end station equipment.Compressed air for vacuum valves, shutters,
etc

All piping installed; final DI water integration to equipment expected in early summer.
Final “as built” flow diagram released in December.

SST Electrical Utilities OverviewTechnical Scope and StatusStandard utilities installation scope that has been used at other NSLS-II beamlines, and tailored to needs at SST. Scope is larger than a typical beamline due to multiple end stations and overall number of power circuits and hardware.AC power distribution from storage ring mezzanine outfitted to FOE and downstream along pylons.Uninterrupted power supply (UPS) for equipment racks.Electrical grounding provisions for all equipment.Released “as built” electrical diagram released in January.

SST Electrical Utilities OverviewTechnical Scope and StatusIncludes cable tray provisions for controls, communication, and vacuum system cabling.Cable tray requirements are developed jointly with the beamline staff, Controls Group, and Electrical Engineering Group.Cable database is maintained by the Controls Group, and includes label IDs and operating voltage of each cable.Cables with voltages above 50V and below 600V will be identified as electrical hazardous voltage.Installation was completed in late 2016.Slide10
Personnel Protection System (PPS) Overview
Beamline PPS Designed to Protect Against Synchrotron and Bremsstrahlung RadiationTechnical ScopeDual chain safety-rated PLC architecture (two manufacturers)Status of PPS functions available on local HMI and EPICSRedundant critical device configurationDoors and labyrinths monitored by redundant and diverse switchesInterface to photon shutters & water flow circuitsInterior warning - revolving beacons and sirens
Bench assembled PPS panelSlide11
Recent PPS Improvements
PPS group has continued to develop and engineer improvements into existing architecture:The mechanical door switches on the hutches will be replaced with magnetic coded switches. Replace B chain magnetic reed switch with switch incorporated in magnetic lock assembly.Where practical, field wires will be directly wired to I/O modules, eliminating intermediate terminal blocks and wires. Using cable tray for cables instead of conduitIncreased reliability and reduction of installation effort.

New reed switch reduces installation
cost and timeSlide12
SST PPS Installation
Overall scope for SST is larger than typical beamlines at NSLS-IINine current photon shutters, plus cabling for tenth future shutter.Ten pairs of vacuum switches for current pink beam transport pipes, DCM, PGM, and current end stations.Four PPS DI water circuits to monitor photon shutters, WBS, DCM, PGM, and masks.PPS conduit was installed in late 2016.Cable pulling and termination is currently in process.FOE control cabinet assembled; downstream box starting.Component integration and system testing scheduled for this summer.Certification by ES&H expected in September.

SST EPS Overview
Protects equipmentBeamline EPS Monitors the
following:
Temperatures of white or pink beam
components.
DI water
flow rates through
components; 13 circuits on SST.
Position of gate
valves.
Over-travel limit switches on some critical
components.
Vacuum pressures in each beamline vacuum
section.
Smoke detectors in equipment racks
Flags
problems
either:
As a warning (gives early indication of problems to the operators
).
As a trip threshold – closes
the front end
shutter immediately upstream.
Will close gate valves in the event of vacuum
problems.

SST EPS StatusStatus through January 2017:
Gathering of EPS requirements and initial design work kicked off in November 2016.Design of the PLC code and EPICS database will start in March.IOC design is ~20% complete.Procurement of system components and hardware is mostly complete.Initial installation at the beamline has startedAll of the EPS cables have been pulled; 75% have been terminated.EPS enclosure is installed and wired at the box.Remaining EPS integration will be done as beamline components and end stations are installed.System testing expected to start in late Spring.Completion of EPS expected in late summer, after all beamline systems are installed.

SST Beamline Infrastructure
scope well defined and understood.Majority of work is already designed, procured and installed at the beamline. Fully capitalizing and benefiting from engineering designs and experiences from NSLS-II Project/ABBIX/NEXT BeamlinesValue engineering and engineering improvements are already being pursued in many areas, particularly for Utilities and PPS.Resources are fully planned to execute remaining work on schedule.
