The CERN-EU High Energy Reference Field (CERF) facility is used in the calibration of neutron dosimeters for radiation protection applications in aviation and high energy physics. A comparison of the facility's microdosimetric spectra obtained with a new Silicon on Insulator (SOI) Microdosimeter and a HAWK Tissue Equivalent Proportional Counter (TEPC) is presented. Experimental data obtained with both devices indicates the presence of a small charged particle flux within the neutron dominated field which makes a non negligible contribution to the dose equivalent.
