MCPL_output ComponentDetector-like component that writes photon state parameters into an mcpl-format binary, virtual-source photon file. MCPL is short for Monte Carlo Particle List, and is a new format for sharing events between e.g. MCNP(X), Geant4, and McXtrace. When used with MPI, the component will output #MPI nodes individual MCPL files that can be merged using the mcpltool. MCPL_output allows a few flags to tweak the output files: 1. If use_polarisation is unset (default) the polarisation vector will not be stored (saving space) 2. If doubleprec is unset (default) data will be stored as 32 bit floating points, effectively cutting the output file size in half. 3. Extra information may be attached to each ray in the form of a userflag, a user-defined variable wich is packed into 32 bits. If the user variable does not fit in 32 bits the value will be truncated and likely garbage. If more than one variable is to be attached to each photon this must be packed into the 32 bits. These features are set this way to keep file sizes as manageable as possible. Example: MCPL_output( filename="voutput", verbose=1, userflag="flag", userflagcomment="Photon Id", merge_mpi=1)
| Name | Unit | Description | Default | |
| polarisationuse | 1 | Enable storing the polarization state of the photon. | 0 | |
| doubleprec | 1 | Use double precision storage. | 0 | |
| verbose | 1 | If 1) Print summary information for created MCPL file. 2) Also print summary of first 10 particles information stored in the MCPL file. >2) Also print information for first 10 particles as they are being stored by McXtrace. | 0 | |
| userflag | 1 | Extra variable to attach to each photon. The value of this variable will be packed into a 32 bit integer. | "" | |
| filename | str | Name of neutron file to write. If not given, the component name will be used. | 0 | |
| userflagcomment | str | String variable to describe the userflag. If this string is empty (the default) no userflags will be stored. | "" | |
| merge_mpi | 1 | Flag to indicate if output should be merged in case of MPI. | 1 | |
| keep_mpi_unmerged | 1 | Flag to indicate if original unmerged mcpl-files should be kept (or deleted). | 0 | |
| buffermax | 1 | Maximal number of events to save ( <= MAXINT), GPU/OpenACC only. | 0 |
