“…To reach the full physics potential of the Belle II physics program, the SuperKEKB accelerator has been designed [11] to exceed this already exceptional performance by a factor of 40, which required a leap in the conceptual design of the machine and represents a real technical challenge.…”

After the first turn-on that occurred at the beginning of 2016, followed by a five-month single beam operation phase, the new SuperKEKB B Factory is presently under commissioning at the KEK laboratory in Japan. The new collider construction is now completed and it is scheduled to deliver the first e + e − collisions in the first half of 2018, opening a new era in the arena of physics at the high intensity frontier. We present in this paper the preliminary results of the first single beam commissioning and describe the Belle II detector upgrade. We will then describe the performance improvements obtained, and present the status of the final phases of the detector assembly and commissioning.

“…The 90/90 degrees phase advances is chosen to achieve a very small emittance of 2 nm. The non-interleaved sextupole scheme [9] was selected due to its property of small tune shift. Considering the symmetry of two IPs and two beams, the lattice CEPC PDR scheme has a four-fold symmetry and the maximum number of sextupole families in the ARC region is 96 [10].…”

“…collisions with a large Piwinski angle [62] -including "superbunch" schemes in hadron colliders [3,39]; "nanobeam schemes" proposed for the former SuperB (together with crab waist collisions [60]) and adopted for SuperKEKB, in which the short length of the beambeam overlap enables the implementation of an extremely low  y * [63];; colliding hadron bunches with longitudinally flat profile [64,65]; or compensating the beam-beam tune shift with electron(-beam) lenses [48] as implemented at the Tevatron [49] and at RHIC [50], and proposed for the HL-LHC.…”
