Mulassis response functions
The SEPEM Mulassis shielding effects tool uses a
response function approach whereby the effects parameters are calculated once for a unit flux in the energy bins defined by a set of data channels. On this page, a response function can be defined, calculated and stored. Applications that use a response function will fold it on the fly with the flux records of the data channels for which it was defined.
Instrument channels and device geometry
When a data table is selected, the page reloads with a selection of particle species and
shielding geometries previously defined. When a particle species is selected, the page reloads again to show the list of flux channels available in the data table for the selected species, from which the channels relevant for the shielding study can be selected by ticking the check boxes.
The user should specify a name (which will be used as a label) and a description for future reference. As the processing time for this application can be several hours, it is run in batch mode, and the outputs will be stored after completion of the run, using the name and description entered prior to pressing the
Run button. The name for the response function
cannot be left blank. If a Mulassis response function with the same name is already stored in the database by the current user, the response function outputs will be over-written.
Once the run has been started, no other activity (except browsing the help pages) is possible on the server (with the current user account) until the run is completed. While the process is running, a page is presented where the user can perform a refresh to check for completion, or kill the running process. The user can log out and return to the server later.
The results of the run consist of a set of files, presented in a table:
The output files are stored in the database, the macro and log files are not.
- the macro file generated for the Mulassis run (the file can be downloaded for reference or to perform a local run);
- the log file of the Mulassis run;
- the Mulassis output files, one for each data channel; these files contain the four analysis types available in Mulassis: fluence, non-ionising dose, pulse height and ionising dose (the user will be able to select the desired effect on the pages where the response function is used).
