Multinucleon transfer reactions near the Coulomb barrier have been investigated based on the improved dinuclear system (DNS) model, and the deexcitation process of primary fragments are described by statistical model GEMINI++. The production cross sections of $^{40,48}$Ca+$^{124}$Sn and $^{64}$Ni+$^{130}$Te based on the DNS model+GEMINI++ have been calculated and compared with the experimental data. The calculated results have reproduced the experimental data. The cross sections of fusion-evaporation reaction, fragmentation reaction and multinucleon transfer reaction in the $40 \leq Z \leq 60$ region are also given in this paper. The results show that in the $40 \leq Z \leq 60$ region, fusion-evaporation and fragmentation reactions have good results in the relatively proton-rich region, but in the extreme proton-deficient region, the MNT reaction is still promising to synthesize proton-rich nuclei.

A special neutron diagnostic system is proposed that facilitates the measurement of neutron fluxes and spectra in the neutronics and tritium production-test blanket module (NT-TBM) without interrupting the operation of the International Thermal-nuclear Experimental Reactor (ITER), for studying the multiplication rate in the neutron multiplier and breeding ratio of tritium in the breeder. This system includes an encapsulated foil activation system, micro-fission chamber detectors (MFC), and a compact neutron spectrometer using a natural diamond detector (NDD). A helium coolant loop with a reasonable diameter is designed carefully for every measurement channel that ensures that the neutron detectors and preamplifiers would work well under a high temperature scenario and that the filling rates of the neutron multiplier (beryllium pebble) and tritium breeder material (Li4SiO4) would not decrease excessively (the expected value≥80%) due to the dimensions of the helium coolant loop.
