  1. Status of ITEP- TWAC facility (ITEP/TWAC ion beams) A.Golubev

  2. Non-Liovillian stacking process U10 Accelerator-Storage ring 34Tm UK Booster Synchrotron 13 Tm Trajectory of the injected beam.

  3. Process of accumulation of an intensive ion beam C4+ t ~ 7,5 min C6+ Oscillogram of beam losses Ni > 1010 Oscillograms for the intensity of the carbon nuclei at an energy of 200MeV/u during accumulation in the U-10

  4. 27.05.03 Группировка пучка С6+ с энергией 213 МэВ/н (fo=695 кГц) перед выводом Beam compression С6+ with energy 213 МeV/u(RF : fo =695 кHz, 10 кV) Oscillograms of the accumulated-beam longitudinal bunching 170 ns FWHA RF and bunch envelopes; Bunch shape.

  5. Ion acceleration to relativistic energies The construction of the booster synchrotron UK and the system for charge-exchange ion injection from the UK into the U-10 allowed research into the possibility of accelerating ions in the U-10 up to relativistic energy. Oscillograms of carbon-nuclei acceleration in theU-10 up to an energy of 4 GeV/u: Blue - beam intensity(1B/108 particles); Red - signal of the magnetic-cycle derivative.

  6. Intensity target values for ITEP-TWAC :·Ion accumulation mode - 300-700 MeV/u ~1012 particles per ~100 ns pulse;· Ion acceleration mode - up to 4 GeV/u and up to 1010 particles/s;(C, Al, Fe, Cu, Zn …….U from the LIS)·Medical application mode - ~ 250 MeV/u, 10 9 - 10 10 particles/s C6+.

  7. Ground plan of ITEP-TWAC accelerator facility Proton Synchrotron У-10 Injector I-2 Proton Radiotherapy Nuclear physics High energy density in matter Laser ion source

  8. Slow extraction to the experimental area

  9. CONCLUSION • By the end of 2005 ITEP-TWAC will be capable of delivering test beams to the experiments: up to 4 GeV/u and up to 1010 particles/s;(C, Al, Fe, Cu, Zn …….U from the LIS)
