  1. FACET User Support Carsten Hast Accelerator Research Division Test Facilities Department hast@slac.stanford.edu

  2. Apologies • I was rather distracted with work for a new Test Beam Project at SLAC: End Station A Test Beams (ESTB) • Use 5 Hz of LCLS 14.6 GeV e- beam in ESA for ILC style Machine Detector Interface and Beam Delivery System studies • Can produce single electrons and hadrons for detector development studies • Interested? e-mail to hast@slac.stanford.edu FACET User Support hast@slac.stanford.edu

  3. Past to Future • Until 3 years ago the Experimental Facilities Department (EFD) supported users in FFTB and ESA etc. • Since 2 years Test Facilities Department (TF) is operating ESB and NLCTA • Mostly SLAC, no users • Since this year TF is supporting all test facilities (ASTA, ESA, ESB, FACET, NLCTA) • All programs are growing at the same time • TF is growing (currently 2 Techs, 2 DAQ/Controls, 1 LLSO, 5 Physicists) • Developing user support • Here is what we can do • Tell us what you need FACET User Support hast@slac.stanford.edu

  4. Users @ SLAC • A SLAC PI will be assigned to each experiment • Training requirements • Every user will need a SLAC computing account • Many training items can be done remotely via web training • Couple of things on first day of arrival • Need to clarify what general training will be needed • Will setup a web page which will lay out what you need to do and when (no training, no work) FACET User Support hast@slac.stanford.edu

  5. After your proposal is accepted Experimental setup needs review and approval to be installed and operated at SLAC • Safety Oversight Committee (SOC) • Brand new process (rolled out on March 1st) • Looks at experimental equipment and will request Safety Officers and others to review your setup • TF will be instrumental in getting the necessary approvals for you • We know how the system works • We are part of the system • We can do many things for you – If you tell us what you want to do • This process can be quite fast for “normal” setups • But if you’ll need “more exotic” components (e.g. hazardous gases) will take more time • Electrical components need to be UL listed (or equivalent) • That’s a tough one, because many devices you are using in your home institutes are not! • SLAC has an inspection process to approve non listed devices • TF can do that • Radioactive sources need to be registered with RP FACET User Support hast@slac.stanford.edu

  6. Resources @ SLAC • With the end of EFD we lost some capabilities for machining parts, especially quick turn around and installation support • Need to reestablish that, though I fear it will be on a reduced level compared to years ago • Mechanical Fabrication Department (MFD) is very good, but can be slow • Most of the vacuum work will be done by the SLAC vacuum shop  needs scheduling • Heavy equipment needs to be lowered by the SLAC Riggers  needs scheduling • Alignment group is available on short notice, but fiducialization will need time • If you need things which don’t exist yet (special gases, cables, lasers, etc.) we need time (and money) to install these • Special DAQ needs will need time to be implemented TF should be your point of contact to start your quest to be successful at SLAC FACET User Support hast@slac.stanford.edu

  7. Location of FACET • More or less in the middle of nowhere • Will establish a User building this year at S20 • Parking will be interesting • Bicycling is a good option • Need lights • Can be quite wet in winter • Underground without easy access  Very careful planning of the experimental setup, the installation procedure and the operation is key to success • Carrying equipment up and down the stairs is very limited (I don’t want to see anybody in the middle of the night carrying a scope in their hands into the tunnel!) • Need to install a small crane to lower stuff up and down ourselves • Tool box down in the Linac (need to know what you will need) • Very small workshop (drill press, saw etc.) in klystron gallery but remember: No training, no work!

  8. Reuse of old FFTB equipment • We build quite a few specialty items, like the sliding vacuum table with 2 beam lines • Reuse • The FACET user community should agree on some common tools, dimensions etc. to make life easier, faster and cheaper • Mark and I will list some inventory of things we have available FACET User Support hast@slac.stanford.edu

  9. Summary • Users will have a SLAC PI who will be responsible for their training assessment and work authorization and work release • Users will be responsible to only do what they have been trained, authorized and released to do • TF will be your point of contact to get started with your equipment here at SLAC • TF will assist with equipment installation and the coordination with other services needed (rigging, vacuum, alignment, etc) • Special requests (DAQ, hardware, gas, laser) will need time to be implemented • Careful planning ahead will be a key ingredient to make you experiment a success FACET User Support hast@slac.stanford.edu
