Integration of the strip barrel staves of the PANDA Micro Vertex Detector — •Tommaso Quagli, Kai-Thomas Brinkmann, Robert Schnell, and Hans-Georg Zaunick for the PANDA collaboration — II. Physikalisches Institut, Justus-Liebig-Universität Gießen, Gießen, Germany

PANDA is a key experiment of the future FAIR facility, under construction in Darmstadt, Germany. It will study the collisions between an antiproton beam and a fixed proton or nuclear target. The Micro Vertex Detector (MVD) is the innermost detector of the apparatus and is composed of four concentric barrels and six forward disks, instrumented with silicon hybrid pixel detectors and double-sided silicon microstrip detectors; its main task is the identification of primary and secondary vertices. The central requirements include high spatial and time resolution, trigger-less readout with high rate capability, good radiation tolerance and low material budget.

Square and rectangular microstrip sensors will be used in the two outer barrels of the detector. The sensors and the front-end electronics will be arranged on linear staves, composed of a carbon support structure with an embedded active cooling system. A flexible multilayer bus will be used to route the signals on the stave towards the DAQ system. The design of the stave, its integration concept and some relevant hardware developments will be presented.

Supported by BMBF, HGS-HIRe and JCHP.
