High-quality single-crystal diamond films, homoepitaxially grown by microwave chemical vapor deposition, have been used to produce diamond-based photodetectors. Such devices were tested over a very wide spectral range, from the extreme ultraviolet (UV) (20 nm) up near IR region (2400 nm). An optical parametric oscillator tunable laser was investigate 210–2400 nm range in pulse mode. In this region, response shows UV visible contrast of about 6 orders magnitude. A time shorter than 5 ns,...
At present, magnetic confinement fusion devices rely solely on absolute neutron counting as a direct way of measuring power. Absolute deuterium-tritium gamma rays could provide the secondary neutron-independent technique required for validation scientific results and licensing tool future power plants. However, this approach necessitates an accurate determination gamma-ray-to-neutron branching ratio. The ratio reaction ^{3}H(^{2}H,γ)^{5}He/^{3}H(^{2}H,n)^{4}He was determined in plasmas at...
