project_type

Type of project that this record represents
MARC:980:ACCELERATOR corresponds to an accelerator, otherwise it is an experiment.

A project can represent a combination of collaboration, accelerator and experiment, depending on the contents of this field. Typical cases are:

collaboration experiment accelerator explanation
present present absent typical case where a collaboration runs a single experiment (e.g. ALICE).
present absent absent non-experimental collaboration (e.g. lattice) or experimental collaboration corresponding to several experiments (e.g. DO).
absent present absent non-unique experiment among the experiments run by this collaboration (e.g. DO Run I).
absent absent present accelerator that is not a collaboration (e.g. LHC).
present absent present accelerator that is also a collaboration (e.g. CLIC).
  • When collaboration is present, the collaboration field contains information about it. Otherwise, it might refer to the collaboration record corresponding to the current accelerator/experiment.
  • When experiment is present, the experiment field contains information about it.
  • When accelerator is present, the accelerator field contains information about it. If not, but experiment is present, it might refer to the accelerator record providing a beam to this experiment.
type:array

Allowed values:

  • collaboration
