| Zusammenfassung | We describe the capabilities and the application of two computer programs, which have been developed in order to facilitate common tasks in neutron spectrometry: GNSR (calculation of response matrices) and SPECTRIX (unfolding). GNSR (Gas-filled Neutron Spectrometer Response) calculates response functions and response matrices of various gas-filled neutron detectors. It can be configured to accommodate the appropriate gas-fillings and supports a number of different neutron beam configurations with a possibility to input calculated or measured neutron beam spectra. The program includes graphical capabilities as well as a context sensitive help system. SPECTRIX implements several unfolding algorithms as well as support algorithms for unfolding and includes graphics capabilities and context sensitive help. We apply both programs to a specific example: Calculation of the response matrix of a ³He detector and unfolding of the neutron spectrum of a thick accelerator target using the calculated response matrix. |
