In situ measurement of the particle linear energy transfer using the sensitive junctions of the device under test

We describe an approach for using charge collection measurement techniques to determine the LET of a particle that reaches the sensitive region with an unknown energy. The method requires that a calibration of the response of the sensitive region to particle LET be established. Then from this calibration, the unknown LET can be determined. We also give recommendation on how to use complex charge collection data to determine the distribution of particle LET reaching the sensitive region and how to correct the particle fluence for this distribution.
