Welcome to the Course on Unfolding of Bonner Sphere Spectrometer Neutron Measurements!

Dear Colleagues,

It is our pleasure to announce that the Course on Unfolding of Bonner Sphere Spectrometer (BSS) Neutron Measurements, will be held at the Paul Scherrer Institute, Switzerland, from July 26th to 29th 2022.

We invite you to participate to this course with focus on the 
introduction to unfolding for BSS with practical applications. Bonner sphere spectrometers (BSS) are widely used for measuring the spectral neutron distribution. The BSS can determine neutron spectra over a wide energy range covering up to 12 orders of magnitude and it has been used for the measurement of neutron spectra at many different types of facilities, such as reactors, accelerators, and medical facilities. The analysis of the measured data, however, requires unfolding methods, which have to be used carefully to obtain reliable results.

The emphasis is on unfolding exercises using different measurement scenarios. The course is intended for those who do spectrometry in neutron or mixed neutron/photon fields and need to analyze their data using unfolding procedures.

This course is organized as part of EURADOS, the main part of it is carried out by Marcel Reginatto (PTB), Eike Hohmann (PSI) and Neil Roberts (NPL) with additional contributions from members of EURADOS WG11.

The workshop will be held from Tuesday morning to Friday noon with the afternoons assigned for practical exercises.
