Presentation Transcript

  1. S.Kuroda ( KEK ) Baseline RTML in TDR( For discussion )

  2. Beam Parameters

  3. Layout

  4. Return Line ( ELTL/PLTL ) • Following the earth’s curvature in ML tunnel V correctors in each Q V dispersion matching by v correctors at both ends The curved orbit is introduced as ‘design’ or orbit distortion?

  5. Diagnostics • Cavity BPM • Laser Wire for emittance measurement New definition of RTML: BC is not included. Diagnostics and correction section upstream of BC1 is included in RTML? Polarization measurement?

  6. Beam Physics Issues • Stray Field • Tolerance ( K.Kubo ) • 2nT for orbit jitter of 0.2sy • This can be corrected by fast feed-forward • Higher for emittance growth • From what the criteria 0.2sy comes?. Criteria for emittance growth?

  7. Stray Field ( Measurement ) Is it OK after all? N.Solyak 2011

  8. Beam Physics Issues (2) • Emittance Preservation ( A. Latina )

  9. Other Beam Physics Issues in TDR • ISR Vertical emittance growth is negligible • Beam-Ion instability ( L.Wang, et al ) • < 2mPa • Halo Formation from Scattering( S.M.Seletskiy ) • 2mPa  2e-6 of beam intensity < tolerance of 1e-5 • Space-Charge Effect • Incoherent space charge tune shift is O(0.15) in v • To be studied
