The energy spectra of primary knock-on atoms (PKAs) are essential for radiation damage assessment in design of accelerator facilities. However up to date the experimental data are still limited, due to the poor mass resolution and the high measurement threshold energies in the conventional setup of nuclear physics experiments using solid state detectors, which are typically above a few MeV/nucleon. In this study, a novel detection system consisting of two time detectors and one dE-E energy detector is proposed and being constructed to measure the PKA spectra. The system and detector design was based on Monte Carlo simulations by using the PHITS code. The PHITS simulations show that the system is able to distinguish the PKA isotopes above 
0.2-0.3 MeV/nucleon for A=2030 amu; the PKA mass identification thresholds decrease to 
0.1 MeV/nucleon for PKAs lighter than 20 amu. The detection system will be tested in the summer of 2017, and the test results will be presented at the conference.

A new detection system has been designed and constructed dedicating for the measurements of primary knock-on atoms and fission fragments, whose cross sections are critical in the design of accelerator driven systems. The detection system consists of two fast timing detectors and one dE-E energy detector. The particle species are identified by two relationships: the time-of-flight (ToF) vs E and dE vs E, and then the kinetic energy of the identified particles can be derived from the ToF. The PHITS Monte Carlo simulation code was employed for designing detectors and estimating the performance of the detection system. The new detection system will be tested at the JAEA Tandem Facility and the Cyclotron and Radioisotope Center (CYRIC) at the Tohoku University in 2017. The preliminary test results along with the PHITS simulations will be presented at the Workshop.
