The Data Handling Processor(DHP) for the DEPFET Pixel Vertex Detector — •Mikhail Lemarenko, Tomasz Hemperek, Hans Krüger, and Norbert Wermes — Universität Bonn, Bonn, NRW

A major upgrade of the current Japanese B-Factory (KEKB) is planned by the fall of 2015. Together with this new machine (SuperKEKB), also a new detector, BelleII, will be operated to fully exploit the higher luminosity, 40 times larger than the previous experiment. One of the major changes in the new experiment will be the introduction of a new sub-detector, close to the interaction point, to allow a precise reconstruction of the decay vertices of the B meson systems. This pixel detector, based on the DEPFET technology, will consist of 20 modules arranged in two cylindrical layers around the beam pipe. Each of the modules will be read-out independently by a combination of analog and digital ASICs placed at both ends of each sensor. The digital chip, the Data Handling Processor (DHP), is designed to control the readout chain and to pre-process and compress the data. The chip structure and the latest results will be presented.

In this talk a general overview of the DEPFET sensor with a focus on the DATA processing part, i.e. DHP chip development, will be presented.
