MOOTH2	Commissioning of SuperKEKB	ion, MMI, vacuum, emittance	4
	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.

	VEPP-2000 e⁺e⁻ collider at Budker Institute of Nuclear Physics was commissioned in 2009 and collected data during three runs in whole designed energy range of 160-1000 MeV per beam. The Round Colliding Beams concept was implemented at VEPP-2000 to get a significant enhancement in beam-beam limit. The beam-beam parameter value as high as 0.12 per IP was achieved at intermediate energy. To obtain more intensive beams and achieve target luminosity at top energies the injection chain upgrade was done during 2013-2016. Presently VEPP-2000 is recommissioned and ready to start data taking.

TUT1AH2	Design of Interaction Region and MDI at CEPC	ion, background, solenoid, radiation	53
	Q.L. Xiu, J. Gao, X.C. Lou, B. Sha, D. Wang, Y. Wang, H. Zhu IHEP, Bejing, People's Republic of China
	The CEPC is a proposed circular electron positron collider to study the Higgs boson more accurately. To make sure the machine works well, the compatibility of the machine and the detector is very important. In order to make sure the detector is compatible with the machine, two kinds of problems must be resolved. Firstly, the mutual influence between the machine and the detector must be well studied. It includes the beam induced background, the influence on the beam status from the detector solenoid field and so on. Secondly, the interface between the machine and the detector must be well designed, including the mechanical supporting, the procedure to assemble the interaction region and so on. In this talk, we present the recent progress of the IR design and MDI study of CEPC. The dominant sources of beam induced background have been studied and some preliminary results are obtained. The compensating solenoid and anti-solenoid will be used to suppress the influence on the beam status from the detector solenoid. A global design of the interaction region is undergoing to balance the conflict of performance between the machine and the detector.

TUT1AH3	The FCC-ee Interaction Region Magnet Design	ion, solenoid, quadrupole, emittance	57
	M. Koratzinos DPNC, Genève, Switzerland
	The design of the region close to the interaction point of the FCC-ee experiments is especially challenging. The beams collide at an angle (±15 mrad) in the high-field region of the detector solenoid. Moreover, the very low vertical beta' of the machine necessitates that the final focusing quadrupoles have a distance from the IP (L') of around 2 m and therefore are inside the main detector solenoid. The beams should be screened from the effect of the detector magnetic field, and the emittance blow-up due to vertical dispersion in the interaction region should be minimized, while leaving enough space for detector components. Crosstalk between the two final focus quadrupoles, only about 6 cm apart at the tip, should also be eliminated.

	J.T. Seeman SLAC, Menlo Park, California, USA
	Funding: Work Supported under US DOE/SU Contract DE-AC02-76SF00515. The schemes for full-energy top-up injection into an e⁺e⁻ collider will be discussed emphasizing technical issues to be accommodated. The issues include energy stability, energy spread control, transverse emittance reduction, transverse position and angle stability, collimation, background control in the detector, detector blanking of event triggers, and bunch filling strategies. Strategies and observations from PEP-II and KEKB will be included.

WET1H3	Beam Instrumentation in SuperKEKB	ion, feedback, kicker, operation	164
	H. Fukuma KEK, Ibaraki, Japan
	SuperKEKB is an upgraded collider of the KEK B-factory (KEKB). Its phase 1 operation has just finished in this June. A BPM system consists of super heterodyne detectors, turn by turn log-ratio detectors with fast gates and detectors for the orbit feedback to maintain stable collision. New X-ray beam profile monitors with multi-slit masks are installed. The bunch-by-bunch feedback system is upgraded using low noise frontend electronics and new 12 bits iGp digital filters. A status of instrumentations of SuperKEKB will be given in this talk.
