5. Injector (LU-20) modernization • It was planned for 2009: • dismounting of the linac vessel and geodethy of all 59 druft tubes – performed (3 month); • new power supplies for corrector magnets; commissioning of the new synchronization system for all linac control channels – done; • exchange of some vacuum chamber parts of the injection channel (new fast vacuum shutters) – done; • Achieved deutron current from laser source >5 mA (before was 3 mA) • 2-3 dedicated beam runs – 4 done; September 2009 G.Trubnikov Egle Tomasi-Gustafsson

6. Beam slow extraction system at maximum energy (V. Volkov) Works on design of new high voltage power supply for the electro-static septum in the LHEP design bureau were completed in autumn 2008. Prototype of such system was constructed and successfully tested up to 140 kV (existing septum power supply allows up to 110 kV only – it corresponds to 2,3 GeV/n extracted beam). Now all the elements of new power supply had been manufactured at LHEP workshops and this system is assembled – 03 Jan 2010: tested up to 220 kV. We plan to install it in the slow extraction sector in order to provide experiments on beam extraction at energy 4 GeV/n during next Nuclotron run. Egle Tomasi-Gustafsson G.Trubnikov
