Možné scénáře
  • Maximální luminosita bez HW změn (fáze 0)
    • Jen 2 IP
    • Zvýšení Nb
    • Max. pole dipólu 9 T
  • Pouze změny interakční oblasti (fáze 1)
  • Podstatné HW změny (fáze 2)

The KEKB Performance

70 x TeVatron

1,7 x PEPII

210 x LEP

2 x LHC

1 x ILC

Luminosity Records:

  • Peak L = 2.1x1034 cm-2 s-1(2x the design value)
  • Daily ∫Ldt = 1.5 fb-1(2.5 x the design value)
  • Total ∫Ldt ~ 950 fb-1(as of July 2009)

1x1034 cm-2 s-1

Replace long TRISTAN dipoles with shorter ones (HER).

Add / modify rf systems.

Redesign the HER arcs to squeeze the emitance.

Low emittance positrons to inject

Low emittance gun

Low emittance electrons to inject

New positron target / capture section

TiN coated beam pipe with antechambers

Project Status

SuperKEKB is a lab priority, part of the KEK Roadmap.

The Japanese government has partially approved the project

Funding in other countries on the way (D,SLO, CZ)

We are proceeding with R&D while awaiting full approval of the construction budget request.

Lineární urychlovač e+e-

Motivace

  • Další fundamentální výsledky lze dosáhnout při ECM~ stovky GeV
  • LHC: 7 TeV
  • Podle shodného mínění nestačí jen jeden urychlovač
  • Ke komplementárním měřením (EW) je třeba e+e-
  • LEP: poslední kruhový urychlovač, po něm musí být elektrony urychlovány lineárně
slide26
Future : e+ e- Linear colliders

High gradient cavities

clic ilc
CLIC ILC
  • Dual beam acceleration technology
  • R&D at CERN ~ 20 y
  • Normal conducting cavities
  • 12 GHz, 100 MV/m
  • Maximum energy 3 TeV cm – Phase I at 0.5 TeV
  • International collaboration around CTF3
  • Well extablished SC rf technology (TESLA, FLASH, XFEL…)
  • Decision in 2004
  • Rf cavities ~ TESLA like
  • 1.3 GHz, 31.5 MV/m
  • Maximum energy 1 TeV cm - Phase I at 0.5 TeV
  • GDE (Global Design Effort) - International collaboration
  • Site independent
