The two large spectrometer magnets are built by seven groups from universities and research institutes in Germany, Italy, Russia, Poland and the UK. The institutions and their abbreviations are listed in Table 1.


Table 1: Table of abbreviations and institutions responsible for the design and construction of the magnets at PANDA.

Five distinct primary work packages have been identified. These comprise the design and construction of the following items.

  1. The coil and cryostat of the Target Spectrometer. The overall responsibility is taken by INFN, Genoa.
  2. The flux return yoke of the Target Spectrometer, which serves simultaneously as multi-layer absorber for a large-angle muon detection system. The overall responsibility is taken by JINR, Dubna.
  3. The large-aperture dipole magnet for the Forward Spectrometer. The overall responsibility is taken by the University of Glasgow.
  4. The support structures and detector mountings for all of the Forward Spectrometer. The overall responsibility is taken jointly by the Jagiellonian University, Cracow (UJ) and the Cracow University of Technology (CUT)
  5. The railing systems and movement of the whole Target Spectrometer and the platform with the Forward Spectrometer detectors. The overall responsibility is taken jointly by the Gesellschaft für Schwerionenforschung, Darmstadt (GSI) and Cracow University of Technology (CUT).
The responsibility for the detector mountings inside the Target Spectrometer remains with the individual detector groups, while the magnet group will provide only mounting points. A detailed list of work packages has been worked out, and responsibilities have been identified, which have been approved by all groups. These are listed in Table 2, where the responsible institutions are listed by their abbreviations specified in Tablee 1. Where responsibilities are shared the main responsible is given first and the secondary is indicated in brackets. The main responsible institution will always supervise the work package and take responsibility for a timely and full completion.


Table 2: Table of work packages listing the individual work packages and the responsible institutions by the abbreviations as listed in Table 1. The institutions listed in brackets are responsible for a specific part of the WP but the overall responsibility is taken by the leading institution.
