ITER Physics Data Model Documentation for neutron_diagnostic

Neutron diagnostic such as DNFM, NFM or MFC

Notation of array of structure indices: itime indicates a time index; i1, i2, i3, ... indicate other indices with their depth in the IDS. This notation clarifies the path of a given node, but should not be used to compare indices of different nodes (they may have different meanings).

Full path name Description Data Type Coordinates
ids_properties Interface Data Structure properties. This element identifies the node above as an IDS structure
ids_properties/comment Any comment describing the content of this IDS {constant} STR_0D
ids_properties/homogeneous_time This node must be filled (with 0, 1, or 2) for the IDS to be valid. If 1, the time of this IDS is homogeneous, i.e. the time values for this IDS are stored in the time node just below the root of this IDS. If 0, the time values are stored in the various time fields at lower levels in the tree. In the case only constant or static nodes are filled within the IDS, homogeneous_time must be set to 2 {constant} INT_0D

Provenance information about this IDS structure
ids_properties/provenance/node(i1) Set of IDS nodes for which the provenance is given. The provenance information applies to the whole structure below the IDS node. For documenting provenance information for the whole IDS, set the size of this array of structure to 1 and leave the child "path" node empty {constant} struct_array [max_size=20 (limited in MDS+ backend only)] 1- 1...N
ids_properties/provenance/node(i1)/path Path of the node within the IDS, following the syntax given in the link below. If empty, means the provenance information applies to the whole IDS. Click here for further documentation. {constant} STR_0D
ids_properties/provenance/node(i1)/sources(:) List of sources used to import or calculate this node, identified as explained below. In case the node is the result of of a calculation / data processing, the source is an input to the process described in the "code" structure at the root of the IDS. The source can be an IDS (identified by a URI or a persitent identifier, see syntax in the link below) or non-IDS data imported directly from an non-IMAS database (identified by the command used to import the source, or the persistent identifier of the data source). Often data are obtained by a chain of processes, however only the last process input are recorded here. The full chain of provenance has then to be reconstructed recursively from the provenance information contained in the data sources. Click here for further documentation. {constant} STR_1D 1- 1...N
