This model of the ESS BIFROST instrument illustrates the use of the "shielding-logger"
components, as described in the publications https://doi.org/10.3233/JNR-190123,
https://doi.org/10.3233/JNR-180088 and https://doi.org/10.1016/j.nima.2018.12.069.
An important note from the author:
Please note that the included Shielding- and Dose- calculators will only give sensible for guides with
borosilicate glass substrate. If the substrate is, e.g. copper, the dose rates from neutrons transmitted
through the coating and captured in the substrate will overshoot the coating contribution significantly,
so that shielding has to be enforced by few tens of centimeters of concrete.
Example: ESS_BIFROST_shielding.instr WaveMin=1
Parameters in boldface are required;
the others are optional.
Minimum wavelength from moderator
Maximum wavelength from moderator
Lowest energy in wavelength band - used for chopper settings
Alternative: highest wavelength in wavelength band - used for chopper settings
Opening time of pulse shapping chopper
Opening of Divergence Slit nr 0
Opening of Divergence Slit nr 1
Opening of Divergence Slit nr 2
Opening of Divergence Slit nr 3
Number of pulses to produce at the source
Bolean flag to print values of interest for debugging. mcdisplay does not work when this is set to 1
Bolean flag to save all neutrons to virtual source file
Bolean flag to indicate that M-values should be printed
