[ Identification | Description | Input parameters | Links ]

The PSI_Focus_shielding Instrument

Special version of the FOCUS Spectrometer at PSI (Paul Scherrer Institute,Switzerland), adapted for illustration of the use of the "shielding-logger" components


  • Site: PSI
  • Author: Rodion Kolevatov, IFE , derived from work by Uwe Filges, PSI
  • Origin: IFE
  • Date: Jan 2004


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, and

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.
