	Y. Funakoshi KEK, Ibaraki, Japan
	After 5 years of upgrade work from KEKB, the Phase 1 beam commissioning of SuperKEKB started on Feb. 1st this year and finished at the end of June. In Phase 1, Belle-II detector and the final focus doublet (QCS) were not installed and no beam collision was performed. Missions of the commissioning in Phase 1 were startup of each hardware component, establishment of beam operation software tools, preparation of Belle-II detector, an optics study and tuning without QCS and the detector solenoid magnet and other machine studies. In this talk, achievements in the Phase 1 commissioning are summarized. Also a plan for the Phase 2 commissioning will be given.

TUT3AH3	Beam-based Impedance Measurement Techniques	ion, impedance, simulation, damping	112
	V.V. Smaluk BNL, Upton, Long Island, New York, USA
	Funding: Work supported by DOE under contract No.DE-AC02- 98CH10886 Characterization of a vacuum chamber impedance is necessary to estimate stability conditions of a particle beam motion, to find a limit of the beam intensity and characteristic times of single-bunch and multi-bunch instabilities. For new accelerator projects, minimization of the vacuum chamber impedance is now the mandatory requirement. For an accelerator in operation, the impedance can be measured experimentally using various beam-based techniques. The beam-impedance interaction manifests itself in measurable beam parameters, such as betatron tunes, closed orbit, growth rates of instabilities, bunch length and synchronous phase. The beam-based techniques developed for measurement of the longitudinal and transverse impedance are discussed, including theoretical basics and experimental results.

WET1H1	Beam Instrumentation Needs for a Future Electron-Positron Collider Based on PEP-II Observations	ion, luminosity, feedback, instrumentation	157
	J.T. Seeman SLAC, Menlo Park, California, USA
	Funding: Work supported by US DOE/SU Contract DE-AC02-76SF00515. Future e⁺e⁻ colliders will operate with many bunches, short bunch lengths, small emittances, high currents, and small interaction point betas. The stability of the colliding beams with these characteristics will depend on detailed, high precision, and continuous measurements. The various beam measurement requirements and techniques will be discussed using PEP-II observations as a starting point.

Characterization of a vacuum chamber impedance is necessary to estimate stability conditions of a particle beam motion, to find a limit of the beam intensity and characteristic times of single-bunch and multi-bunch instabilities. For new accelerator projects, minimization of the vacuum chamber impedance is now the mandatory requirement. For an accelerator in operation, the impedance can be measured experimentally using various beam-based techniques. The beam-impedance interaction manifests itself in measurable beam parameters, such as betatron tunes, closed orbit, growth rates of instabilities, bunch length and synchronous phase. The beam-based techniques developed for measurement of the longitudinal and transverse impedance are discussed, including theoretical basics and experimental results.
