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_at_slac.stanford.edu

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

Users _at_ 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)

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 youll need more exotic components (e.g.
  hazardous gases) will take more time
• Electrical components need to be UL listed (or
  equivalent)
• Thats 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

Resources _at_ 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 dont 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

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 dont 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

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
