In order to fulfill the goal of producing high rates of doubly strange hyperons the ¯PANDA collaboration will use the antiproton ring HESR at the future facility FAIR. The low energy hyperon production by an antiproton beam requires to insert a solid target inside the ring. Unwanted side effects of such an insertion are the overwelming amount of annihilations, which would make the detectors blind, and the fast depletion of the bunch, which circulates inside the ring. The use of a very thin target and the technique of beam steering seem to be a satisfactory solution to the above problems and will be described here.

The $\overline{\text{P}}\text{ANDA}$-experiment will be one of the main experiments at the upcoming Facility for Antiproton and Ion Research (FAIR) at the GSI in Darmstadt. The fixed target experiment will explore $\overline{\text{p}}$p annihilations in the charm mass region with intense, phase space cooled beams with momenta between 1.5 and 15 GeV/c. The innermost subdetector of $\overline{\text{P}}\text{ANDA}$ will be the Micro Vertex Detector (MVD) and consists of silicon strip and pixel detectors. The MVD can be further divided into two sub-structures. A barrel-structure around the vertex and a disc-structure in beam direction with six disks of different size. The last two disks are hybrid disks with trapezoidal strip sensors in the outer layer surrounding a smaller ring of pixel sensors in the inner part. The other disks are made only out of pixel detectors. The first trapezoidal prototype sensors were produced by CiS\footnote{Forschungsinstitut f\"ur Mikrosensorik und Photovoltaik GmbH} and have a stereo angle of $15^{\circ}$ with 512 strips per sensor side and a strip pitch of $67.5\,\mu\text{m}$. In order to operate and test the prototype sensors, they were chracterized with a probestation as well as with a dedicated testboard. A first beam test was done at COSY\footnote{Cooler Synchrotron at Forschungszentrum J\"ulich GmbH} with protons of $2.95\,\text{GeV/c}$ and $800\,\text{MeV/c}$ in December 2013 and January 2014.
