Description

This instrument is a model of the FOCUS Spectrometer at PSI, Villigen, CH, modified to illustrate
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.

Input parameters

Parameters in boldface are required; the others are optional.
