	Siberia-2 is a synchrotron light source with electron beam energy up to 2.5GeV, currently undergoing upgrade of controls hardware and software. Ocelot, an accelerator physics framework, was integrated with the new orbit correction system for high level beam control. We describe the steps taken for simulation studies of orbit correction strategies on a virtual machine model, integration of the software into the control system and experimental results.

WEPRO012	New Injection System of Siberia-2 Light Source	1965
	S.I. Tomin, V. Korchuganov NRC, Moscow, Russia
	The storage ring Siberia-2 is SR source of second generation with circumference 124 m. The electron beam is injected into the ring at the energy 450 MeV. The Siberia-2 injection system was initially consisted of two high voltage rectangular pulses generators connected to the two in-vacuum strip – line kickers of traveling wave (wave impedance 50 Ohm) – a pre-inflector and an inflector. The amplitude voltage was 25-35 kV with 20 ns pulse duration and 2-3 ns pulse front/fall. Recently the new injection generators were proposed. Injection system now includes the same kickers and the new 1 microsecond pulse duration and 10 kV voltage amplitude generators.

Siberia-2 is a synchrotron light source with electron beam energy up to 2.5GeV, currently undergoing upgrade of controls hardware and software. Ocelot, an accelerator physics framework, was integrated with the new orbit correction system for high level beam control. We describe the steps taken for simulation studies of orbit correction strategies on a virtual machine model, integration of the software into the control system and experimental results.
