Radiation-to-light converters for nuclear environments: deep red emitters

This report gives the preliminary results on work done to find a scintillator that is compatible with high-bandwidth, long-distance fiber-optic transmission. The requirements for such a scintillator are: (1) emission in the near-IR; (2) linear output over 2 to 3 decades of input excitation; (3) time response < 2 ns; and (4) immunity to radiation damage. The behavior of single crystal cadmium sulfide (CdS) and cadmium selenide (CdSe) was examined under electron and laser excitation. Both crystals emit in the deep red, however, time response was found to be slower than 2 ns. Neither crystal exhibited good linearity over the entire range of input excitation.

Theoretical studies of shock dynamics in two-dimensional structures. V. Microscopic constraints on shock-induced signals (open access)

Theoretical studies of shock dynamics in two-dimensional structures. V. Microscopic constraints on shock-induced signals

Molecular dynamics calculations are presented that address the extent of microscopic detail that can be deduced from macroscopic gauge measurements of shock propagation in condensed systems. Large asymmetrically shock-loaded lattices were simulated, varying the initial temperature and the strength of shock loading. Randomly-placed mass defects were introduced into the lattice, and the degradation of the shock front with the subsequent development of fracture and chunky spall were studied and compared with the coherent microscopic spall found for perfect lattices.
