Importing Laser Beam Energy Normalization Data

VISRAD can import laser beam energy data from TSV- and CSV-formatted files. To view the format for the file contents, see Laser Beam Energy Data Files.

Energy data are used to normalize the time-dependent beam powers of each beam such that their time-integrated powers equal the input energies.

To import energy data into VISRAD, select File | Import Laser Beam Data | Energies for Normalization. When importing the data, a list of beams for which energy data are found is displayed.

In addition to the beam names, only one column is read in during import. The energy column to be imported is specified using the combo box at the bottom of the table.

The selected energy data (which is highlighted in the table) for all selected beams is read in and stored, and the beam power is set up to Normalize to Beam Energy (i.e., for each beam read in, its time-integrated power will be normalized to the input energy). If the energy is negative, its value is set to zero.

For NIF, the imported energies are assumed to apply to blue cone powers.
