Abstract :
For the Belle-II experiment at KEK, a Central Drift Chamber (CDC) with readout electronics is required to be upgraded to cope with the design luminosity of 8 × 10 35 cm − 2 s − 1 . Not only the readout electronics will be completely replaced, but also the wire chamber itself. The new readout electronics system must handle higher trigger rates with less dead time. The front-end electronics are located close to detector and send digitized signal through optical fibers. The Amp-Shaper-Discriminator chips, FADC and FPGA are assembled on a single board. This paper will give an overview of the Belle-II CDC and present results of the performance of the readout board in a test beam.
