	The project, started in 2007 is directed to creation of Tubular Electron String Ion Source (TESIS) and to basic studies of electron strings in tubular geometry. The collaboration consists of JINR (Dubna) and Russian Federal Nuclear Center (Sarov, Russia), Manne Siegbahn Laboratory (Stockholm, Sweden), TRIUMF and Atomic Energy of Canada Ltd. (Canada). Tubular concept of ion source has been proposed few years ago. Preliminary theoretical estimations and numerical simulations have been done,** that allowed to start experimental realization of this project. New tubular source with a superconducting solenoid up to 5 Tesla should be constructed in 2009. It is expected that this new TESIS (“Krion-T1”) will meet all rigid conceptual and technological requirements and should provide ion output on a level, approaching to 10 mA of Ar¹⁶⁺ ions in the pulse mode and about 10 mA of Ar¹⁶⁺ ions in the average current mode. Having these output parameters, “Krion-T1” TESIS should be an operational prototype of further TESIS sources for all kinds of the possible applications. Simulation results and a basic scetch of the TESIS construction will be presented. Donets E. D. et al. Rev. Sci. Instrum. 73, 696 (2002). Donets E. D., Donets E. E., Becker R. et al. Rev. Sci.

	Compact superconducting isochronous cyclotron C400 has been designed at IBA (Belgium) in collaboration with the JINR (Dubna). This cyclotron will be used for radiotherapy with proton, helium or carbon ions. ¹²C⁶⁺ and ⁴He²⁺ ions will be accelerated to 400 MeV/u energy and extracted by electrostatic deflector, H²⁺ ions will be accelerated to the energy 250MeV/u and extracted by stripping. We describe the parameters of the cyclotron, the current status of development work on the cyclotron systems. Reports on the status of the C400 project have been given regularly. Therefore, we will focus on the progress which has been achieved since recent reports in Cyclotron 2007 and EPAC 2006 conferences. The project will be ready to begin construction in the nearest future.
THPP056	Simulations of Incoherent Vertical Ion Losses and Cooling Stacking Injection	3494
	E. Syresin JINR, Dubna, Moscow Region
	The cooling stacking injection at a synchrotron is applied to obtain a high intensity of the stored coasting ion beam. The efficiency of cooling-stacking injection is defined mainly by two parameters: the cooling-accumulation efficiency and the ion life time. The life time of new injected ions usually is essentially smaller than the stack life time for high intensive ion beams. The incoherent loses of new injected ions are related to a multi scattering on residual gas atoms and a vertical heating caused by ion stack noise. The short life time of new injected ions restricts the efficiency of the cooling stacking injection The life time of new injected C⁶⁺ ions is shorter by 2 times than stack life time at HIMAC cooling stacking injection. The life time of new injected protons in S-LSR is smaller by 2-3 orders of magnitudes than the stack life time. The analytical estimations and BETACOL simulations of vertical incoherent ion losses and cooling stacking injection are presented.
