Dosimetry with test structures of the PANDA Micro-Vertex-Detector — •Nils Tröll — II. Physikalisches Institut, Giessen

Electrical characterization and radiation damage is carried out on double-sided silicon strip detectors and pin diodes representing a test structure with electrical properties for the Micro-Vertex-Detector (MVD), which will be the innermost tracking detector of the PANDA experiment.

Therefore, the silicon diodes of the MVD are used in a dosimeter con- cept for measurements of ionizing radiation dose. The energy calibra- tion is carried out at the Marburg Ion Beam Therapy Centre (MIT) and by various laboratory radiation sources. Signal generation by the sensors is observed to determine performance parameters for the MVD. Additionally, static electrical properties, like the depletion voltage, al- low a characterization of radiation tolerance of the silicon diodes. The work is supported by the BMBF.
