Zusammenfassung: | Compilation of prompt photon spectra recorded in ISO neutron fields produced at PIAF (PTB accelerator facility) by using a 1.5'' x 1.5'' CeBr3 detector. This data set is an appendix to the article “Quantitative investigation of gamma radiation in accelerator produced ISO neutron fields” by H. Dombrowski and R. Nolte. The spectra are depicted in this article. The time-of-flight method was used to detect direct photons. By performing shadow cone measurements, a background subtraction was performed. In addition, the random background was subtracted. The latter consists of net spectra (likewise foreground minus shadow cone background spectra), which were recorded using a time-of-flight window located earlier on the timeline than the arrival of the prompt photons. |
Bemerkung: | Recommended reading software: InterWinner, Genie2k, Maestro, WinSPEC, Cambio, ... Description of the individual files: Each spectrum is available in the IEC format (as defined in IEC 1455) and the SPE format (defined by IAEA, with the exception that the energy axis is defined according to widespread commercial spectrometry software). Because each data set is the result of two subtractions, negative channel entries are possible. This may cause problems when using certain commercial software packages. Therefore, all spectra are also available with removed negative channel entries, marked by “_nn” (no negative counts) in the file name. A consequence of the normalisation to the measured target charge is the fact that the spectra have no integer entries. Any software which is used to depict or process the spectra has to handle at least single precision channel entries. The following system is used to identify each spectrum file: The spectrum name includes a tag denoting the target and the neutron energy of the corresponding ISO neutron field. Neutron energies: According to ISO 8529. Target tags: Li - pure lithium LiF - lithium fluoride Dg – deuterium gas target T – solid state tritium target (tritium implanted in titanium) |
