The following files are the spectral files as used in the NKS-B REMSPEC activity.
Each zip file contains the relevant spectrum in a range of formats as described fully in the NKS-B REMSPEC report.
NKSPEK refers to the test spectrum (many nuclides). NKSCALIBT refers to the calibration spectrum, (The calibration spectrum should not be used to determine efficiency, only energy and shape calibrations. It contains 137Cs, 133Ba, 88Y and 40K).
All files and data are provided "as is" without warranty or assurances of any kind. The authors make no warranties, express or implied, that they are free of error, or are consistent with any particular standard of quality or that they will meet your requirements for any particular application. They should not be relied on for solving a problem whose incorrect solution could result in injury to a person or loss of property or data. If you do use them in such a manner, it is at your own risk. The authors disclaim all liability for direct, indirect or consequential damages resulting from your use of the following files.
There are 9 versions of each spectrum, as following:
The ordinary test/calibration spectrum NKSPEK1/NKSCALIBT1.
The test/calibration spectrum with coincidence summation switched off (NKSPEK2/NKSCALIBT2).
The test/calibration spectrum with high resolution where 1 FWHM was equivalent to 1 channel (NKSPEK3/NKSCALIBT3).
The test/calibration spectrum with high resolution and no coincidence summation (NKSPEK4/NKSCALIBT4).
The test/calibration spectrum with just the photopeaks (NKSPEK5/NKSCALIBT5).
The test/calibration spectrum with just photopeaks and no coincidence summation (NKSPEK6/NKSCALIBT6).
The test/calibration spectrum with just the photopeaks and high resolution (NKSPEK7/NKSCALIBT7).
The test/calibration spectrum with just photopeaks, no coincidence summation and high resolution (NKSPEK8/NKSCALIBT8).
The test/calibration spectrum minus the photopeaks (NKSPEK9/NKSCALIBT9).
Efficiency data is provided within the efficiency.txt file. Fuller elaboration on both the spectra and the efficiency data may be found in the relevant NKS report.
