Detector Parameters#

This subsection contains the specific information of the detector. Detector position file defines the files that Lethe uses to read the detector positions. This file includes the position of the detector face’s center and the position of a point inside the detector on its axis.

  set detector positions file         = positions.detector
  set radius                          = 0.0381
  set length                          = 0.0762
  set dead time                       = 1e-5

  • detector positions file: Filename of the text file with positions of detector(s)

    Options: Any text file with .detector extension with the required header: face_positions_x face_positions_y face_positions_z middle_positions_x middle_positions_y middle_positions_z

  • radius: Radius of detector(s) (all detectors must have the same dimensions)

    Options: Any positive float (default value: 1)

  • length: Length of detector(s) (all detectors must have the same dimensions)

    Options: Any positive float (default value: 1)

The following parameters are variables in the gamma-ray Monte-Carlo model from Beam et al. (1978) [1]:

  • activity: Radioactive source activity of the tracer [Beq]

    Options: Any positive float (default value: 1)

  • dead time: Dead time of the detector per accepted pulse [s]

    Options : Any positive float (default value: 1)

  • attenuation coefficient reactor: Total linear attenuation of light coefficient of the medium and reactor wall []

    Options: Any positive float (default value: 1)
