  1. Muon Beams from ISIS Rob Edgecock Particle Physics Department Single Particle High Intensity Bunches “Blast” test

  2. Cooling Experiment • Target is a 10% reduction in emittance • This requires 1% precision in everything • Statistical requirements are small, < 10k events/point • Plan is to pulse rf at 50Hz, with 100μs per pulse • Muon momentum  350 MeV/c

  3. Note: rf pulsed at 50Hz, 100μs per pulse ISIS: • 50 Hz, >100μs at maximum energy, 800 MeV  ISIS is cw for cooling experiment! • 2 bunches, each 100ns long, separated by 230ns • Each makes 200 turns during 100μs 20000 turns/sec • Need to produce ~1 muon/turn in the experiment • Walk in the park! Single Particle Beam

  4. ISIS 800 MeV proton synchrotron 2.5  1013 proton per pulse 100 ns pulses at 50 Hz

  5. 20.0 70.0 1.0 20.0 6.0 8.0 6.0 Titanium target for HEP test beam

  6. HEP Test Beam

  7. Production Rates Estimated using existing target and beam line. For 0.1% of protons passing through the target, particle transport down the HEP test beam: + (values to 10%)

  8. But…...

  9. High Intensity Bunched Muon Beam + Blast Test • Useful for: • Cooling, e.g. with ring cooler • Target tests • Capture tests • Cooling component tests

  10. Rates….. 10 x IC: 10 bunches/sec  For 107 protons  0.03μ/p p/s in 10 7ns bunches With 10cm long, 2cm radius target and 7.5m decay line 

  11. Rates….. Assume: can catch 25% of pions and all muons with pl > 0. and pt < 120 MeV/c Muon rate/s in 1% momentum bins

  12. Conclusions • ISIS can provide ALL the beams required for cooling and other NF studies: Single particle ~ rate similar to PSI Bunched beam ~ rate comparable to anywhere Blast test ~ rate comparable to anywhere • Large experimental halls available • Single particle beam already exists • Tests of rates to be made within a couple of weeks • Power, cooling, etc also exist in this hall • In principle, it is possible to provide a very high intensity proton beam to the same experiment
