Presentation Transcript
switchyard 120 project1
Switchyard 120 project
  • Phase I low intensity beams to Meson- Completed 2002
  • connection to Main Injector & 800 GeV SY
  • replace cryo. left bends encl C with conventional magnets
  • Phase II clean transmission for High Intensity - Not Done
  • -add quads F2, F3 manholes
  • -move electrostatic septa from F1 encl. to M01 enclosure
  • -rework M01 3-way split
  • -rework (eliminate) “Meson Train” target box/collimators

MTest Beam Layout and Modes

Movable downstream 30cm target location

Movable upstream 25 cm Al target

Meson Test Beam Facility

Mtest secondary beamline

Proton Mode: 120 GeV protons transmitted through upstream target

Pion Mode: 8-66 GeV beam tuned for secondaries from upstream target

Low Energy Pion Mode: 1-32 GeV beam tuned for secondaries from downstream target

more spill options
More Spill Options

Currently operating with a 4 second long slow spill

once per minute (6 sec. total, 12 hours/day or 5%)

We have in the past changed from 4 sec to 1 sec,

but done manually it required a handful of experts

one or more shifts

  • 4 sec or 1 sec Slow spill length change automated-

Operations changes event type and few parameters

(Denton Morris, Dave Capista, Wally Kissel, Paul Allcorn, Peter Prieto,

Charlie Briegel, Chuck Brown)

  • “Pings” 2ms width slow resonant, ~5 pings per pulse
slide12

Changes to Main Injector QXR for Pings

Peter Prieto

  • Added an external 150V 15A Power supply for Pings.
  • Switch added in QXR Regulator so it can add Ping current on during spill.
  • Controls hardware added so Ping events ($33) through TCLK. Up to 8 events per spill.
  • MI-30 test that QXR can extracts beam with a 1 sec cycle and a 4 sec cycle and Pings can be generated during either one.

50 amps with

a 2ms duration

Need to test QXR driver software and then ready for beam test.
