TH003 Development of a mover having one nanometer precision and 4mm moving range (2008)
Y. Morita, S. Yamashita, Y. Higashi, M. Masuzawa, R. Sugahara, H. Yamaoka
In order to have an experience on movers having a nanometer precision, a mover has been fabricated and its performance is tested. In the ILC, range of about 1mm is required to cure the long term...
DYNAMIC BEAM-BEAM EFFECTS MEASURED AT KEKB (2008)
T. Ieiri, Y. Funakoshi, T. Kawamoto, M. Masuzawa, M. Tobiyama
A series of measurements were carried out to investigate the dynamic beam-beam effects. The beambeam kick and the beam-beam tune-shift were obtained by comparing the beam parameters between a...

The commissioning of the KEKB B–Factory storage rings started on Dec. 1, 1998. The two rings both achieved a stored current of over 0.5 A after operating for four months. The two beams were...
LATTICE DIAGNOSTICS USING SINGLE KICK CLOSED ORBIT AT KEKB (2007)
Y. Ohnishi, K. Akai, N. Akasaka, A. Enomoto, J. Flanagan, H. Fukuma, ...
We have measured beta functions using single kick closed orbit at KEKB. The measured beta functions were compared with the model lattice and gradient errors were extracted from the result in a beta...
Compensation of the Crossing Angle with Crab Cavities at KEKB (2007)
Abe, T., Akai, K., Akemoto, M., Akiyama, A., Arinaga, M., Ebihara, K., ...
Crab cavities have been installed in the KEKB B--Factory rings to compensate the crossing angle at the collision point and thus increase luminosity. The beam operation with crab crossing has been...
