The PANDA experiment (antiProton ANnihilation at DArmstadt) is one of the four key experiments to be operated at FAIR (Facility for Antiproton and Ion Research), which is currently under construction near Darmstadt/Germany. This fixed target experiment will address a wide range of open questions in the field of hadron physics.
The detector consists of at target as well as a forward spectrometer to fully exploit the forward boosted collisions of antiprotons with dense hydrogen or nuclear targets.
Phase-space cooled antiprotons with momenta in the range of 1.5 GeV/c to 15 GeV/c provided by the High Energy Storage Ring (HESR) allow for high precision line-shape scans.
The ability to perform exclusive reconstruction of arbitrary final states enables a physics program including topics such as spectroscopy in the charmonium and open-charm region, proton structure, and hyperon and hypernuclear physics.
The talk will give an overview of the PANDA experiment and highlight the most important aspects of the physics program.

This document presents the technical layout and the cost assessment for the infrastructure of the PANDA experiment, comprising the following major items:
- Supports: Mechanical structures to support the experimental setup, fixed and removable platforms to house equipment and to assemble the experiment, including staircases, ladders,fences, racks and related tools.
- Supplies: Distribution systems for electrical power, grounding, fluids and gases.
Based on this, the current integration planning and the installation procedure are described.
UPDATE July 3: Updated version v1.0 submitted to external referees.
UPDATE August 28: Updated version v2.0 for inspection by the PANDA CB before submission to ECE.
UPDATE September 14: Version v3.0 for submission to FAIR ECE. Bibliographies completed.
The PANDA Experiment, which is located at the High Energy Storage Ring at the FAIR accelerator
center in Darmstadt, Germany, is optimized for questions of hadron physics.
With this detector it will be possible to discover new states and measure their line shapes as well as the
line shapes of already known states very precisely.
To normalize the energy scan measurements exact knowledge of the luminosity is required.
The luminosity at PANDA will be determined from the angular distribution of elastical antiprotonm
proton scattering. In order to achieve an absolute measuring accuracy of 5% , the tracks of the scattered
antiprotons will be measured by four planes of thinned silicon detectors (HV-MAPS).
HV-MAPS are pixel sensors with integrated readout electronics. They will be operated with a reverse
voltage of 60 volts to increase their radiation hardness.
The four detector planes consist of CVD-diamonds on which the sensors are clued. To reduce the
multiple scattering the detector is operated in a vacuum.
The concept of the luminosity detector is presented and technical aspects such as the vacuum system,
cooling, electronics, and sensors are discussed, as well as insights into data analysis.
