Layout Each hutch is 10 m long FEH NEH FEE Tunnel Experiments: Atomic Physics Front End Enclosure Fast Close Valve Slits Attenuators Shielding Experiments Optics Structual Bio Nano-scale Femtochem FEL Measurements & Experiments: Low Power Imaging High Power Imaging Spectrometer Calorimeter Flipper Mirror Experiments: Optics Warm Dense Matter

Major Effort Areas Getting an accurate count of all devices Naming devices (and extending SLC convention) Aligning XTOD controls devices with LCLS global standards Reviewing cost+schedule Installing EPICS at LLNL

Counting Devices Layout and instrument list has changed since original design Original design was not “EPICS-aware” Need block diagram or even one-line diagram to accurately define PLC, IOC and other controls- specific components LCLS-wide standards are (just) now being set All of above are basis for accurate cost+schedule

Will conform to (and extend) SLC conventions Naming Devices Will conform to (and extend) SLC conventions Especially for “SLC-aware” devices Allows uniform notation on spread-sheets, one-line diagrams, as well as EPICS configuration Implicitly forces accurate counting

Safety must be engineered in LCLS Global Standards Safety must be engineered in Commerical products are one way to ensure this (UL, CE, …) Initial Q/A will take place at LLNL for many items

LCLS Global Standards… Motor/Encoder chains: OMS58 in VME+transition card+power “brick”: 3 vendors; extra box+cables; great reuse of EPICS practice; parts long-lived Newport XPS single-box: turnkey; TCP/IP field- bus; new driver (and motor record?); rapid evolution of product likely Other?

LCLS Global Standards… Vacuum/Gas: Controllers & Architecture “Smart” controllers + inter-controller wiring + serial to EPICS Wiring complexity; less global integrity “Dumb” controllers+PLC+ Ethernet/IP to EPICS Global integrity; simple wiring ControlLogix vs. FlexLogic Trade-offs in cost, need for wire-centers, availability of EPICS driver

LCLS Global Standards… Choices for Gauges MKS-937A w/317-CEP and 422-CCG 15msec response option Other? Choices for Ion Pumps Dual; Quad; ? MPS-2 SafeCONN Kaiser StarCell

Reviewing Cost+Schedule Accurate device count supports: I/O hardware and cabling costs Approx $200K to be added for master PLCs Configuring+Commissioning Effort Approx 1500 hours to be added for Tunnel Fixed costs as well: Server for LLNL prototyping Licenses (PLC…) Any new drivers

Borrow small VME crate, CPU, EVR and EVG from SLAC EPICS at LLNL Set up a server RH Linux or MacOS X? Keep CVS at SLAC Intellectual property issue? Borrow small VME crate, CPU, EVR and EVG from SLAC Gas Attenuator prototype is first application First use of PLC Will train LLNL staff
