Questions for Luminosity Performance

What limits luminosity performance at higher bunch current ?
What is a source of beam-beam blowup ?
Large Piwinski angle is problem ?
Chromatic X-Y couplings at IP ? ← X-Y couplings at IR
Interference between lattice nonlinearity and beam-beam ?
Higher bunch current product > 0.3 mA2

Issues of Machine Operation
A. Luminosity Performance
1. X-Y coupling and chromatic X-Y coupling
Correction scheme of X-Y couplings both local and global.
X-Y coupling at IP and Y-LCC (source of chromatic X-Y couplings)

2. Injection
Stability of bunch charge and small emittance
2-bunch injection operation (bunch charge equalization)
Orbit stability of injected beams (Linac and BT)

X-Y coupling affects both injection
and BG.

3. Unstable for higher bunch current due to Beam-Beam: I+I- > 0.3 mA2
4. Horizontal beta squeezing in HER (down to 60 mm)
Synchrotron radiation on PXD
Adjustment of horizontal angle at IP affects horizontal dispersion. (Need to correct)

B. Belle II Beam Background
Injection background in LER (spikes, long-time consecutive background)Strategy

We keep βy* = 1 mm as the baseline.
Number of bunches is 783 or 1565 for physics run.
Startup and Machine study for 3 weeks in Match
Physics run is for about 100 days.
Target : Average luminosity for physics run is more than1.8 x 1034 cm-2s-1.
Make veto dead time less than 5 %.

10New Items

New additional vertical collimator in LER (D06V1)
3 vertical collimators in total (D02V1, D06V1, D06V2)
We expect detector background can be reduced in LER.

Crab waist in LER
Preparation for HER is on-going.
We expect improvement of luminosity performance and reduce beam-tails (a part of BG source)
