An equation for the peak-to-total ratio, P, of a germanium detector is proposed in the following form. P = ε_(p)/ ε_(t) + a(V/A) + b(V/A)~(2)/2 where ε_(p)/ε_(t) is the ratio of the photoelectric to the total detection efficiency for a germanium detector, VIA ...
Full-energy Peak Efficiency and Peak - to - Total Ratio of Well-type HPGe Detectors for Gamma Rays 来自 ResearchGate 喜欢 0 阅读量: 22 作者: MI Abbas 摘要: The Radiation Physics Laboratory, Physics Department, Faculty of Science is currently the only center in Alexandria city that award a ...
The total efficiency can be determined from the full energy peak efficiency, provided the peak-to-total ratio is known. For a given high purity germanium (HPGe) detector, one can establish an intrinsic peak-to-total (P/T) efficiency curve using a set of measurements performed with "single"...

If the gate driver operates mostly in the linear region, the ratio of power dissipation that the gate driver IC experiences is: If RDS(ON)_N = RDS(ON)_P = RDS(ON), Equation 2 can be simplified to: The total power the gate driver IC experiences from the switching of the power ...
It was proved that the peak value of the power oscillation is mainly determined by the power loss and time interval during HVDC commutation failure, the frequency and damping ratio of dominant area oscillation mode, and the ratio of total inertia constants of the two area power systems, and ...
