	H-minus cyclotron has the advantage that high intensity internal beam can be extracted from the acceleration chamber with practically 100% efficiency by transformation H-minus ions into H-plus ion by using thin foil. The extraction system is consists from the probe with stripping foil, extraction window in the vacuum chamber and two correct magnets to match the extracted beam with beam transport line. The beam optics calculations in the measured magnetic field make it possible to find optimal relative position of the extraction system elements as well the parameters of the extracted beam with energy 40 - 80 MeV. At present time the beam is extracted from the chamber with efficiency 100 % and there is good agreement with the optic calculations.

THPSC031	Power Supplies for IHEP Negative Hydrogen Ions Source	power-supply, ion, extraction, ion-source	612
	B.A. Frolov IHEP, Moscow Region, Russia V.S. Klenov, V. Zubets RAS/INR, Moscow, Russia
	The source of negative hydrogen ions is constructed at IHEP for the implementation of multiturn charge-exchange injection to increase the intensity of IHEP buster. Surface-plasma ion souce (SPS) with Penning discharge is selected as a source of H-minus ions. A set of power supplies for SPS, which includes the extraction voltage power supply, the discharge power supplies, the hydrogen gas pulse valve power supply, cesium oven and cesium storage device temperature controllers, was designed, constructed and tested on the equivalent loads. This set of power supplies will allows for commissioning and testing the ion source with the beam extraction energy up to 25 keV and repetition rate 25 Hz.

	V.S. Klenov, S. Bragin, O.T. Frolov, S.E. Golubovski, O.V. Grekhov, O. Volodkevich, V. Zubets RAS/INR, Moscow, Russia
	The emittance measuring device has been developed for operational control of INR RAS linac 400 keV H-minus injector beam parameters. It includes the "pepper-pot", the quartz screen, the CCD camera, PC, the software for camera data processing and beam phase portrait formation. The device has been mounted at the first straight section extension of H-minus LEBT after 45 degree bending magnet. When the bending magnet is switched off the device is possible to measure and to represent single shot beam phase portrait. The results of the H-minus beam emittance measurements and the device performance have been discussed.
