The DEPFET pixel detector for the Belle II experiment at SuperKEKB

Abstract

The Belle II experiment, an upgrade of the existing Belle detector at the e(+)e(-) SuperKEKB collider at KEK, has chosen a pixel detector built with the DEPFET technology for the two innermost layers. The physics goals of the experiment impose challenging requirements to the design of the pixel detector in terms of performance, material budget and power consumption.

This paper evaluates the DEPFET pixel detector for Belle II and the various system aspects behind its final design.
