Upgrading the backend of the pipeline readout system for Belle II
The Belle II experiment at KEK will be a successor to the Belle experiment. Belle II will start operation from 2015, searching for subatomic particles beyond the standard model. The pipeline readout system for the Belle experiment will be unable to satisfy the requirements of Belle II, because the luminosity of the SuperKEKB accelerator will be about 40 times higher than that of KEKB. We have moved the digitizer to front-end electronics and upgraded the back-end part, as well as replacing the processor on the readout module. We report here the upgrade plan and the throughput of the back-end part.
sBelle Design Study Report
In this note, we compile results of various simulation studi es for the upgrade of the Belle detector. Based on these studies, we propose a set of optimum or appropriate parameters for the detector.
Secoiridoids from Olea europaea
Abstract Three new secoiridoids have been isolated from the leaves of Olea europaea along with the previously reported. The compounds were identified by spectral means.
