The thickness of the unresponsive layer of silicon on a surface barrier detector was undetectable. Alpha particles passed through the layer at normal incidence and at 60◦ with respect to the plane of the detector. Electronic drift obscured the difference between the two measured energies. The minimum detectable thickness of silicon for the system is (70± 8) μg/cm, or (30± 3) μm. Future experime...
A novel SOI (Silicon-On-Insulator) pixel photo detector with full depletion and backgate surface potential pinning is proposed in this paper. The detector greatly increases charge-to-voltage conversion gain while stabilizing the operation of SOI circuits. Low noise and wide dynamic range operations are attained. A double doping technique increasing potential barrier to holes at the surface regi...
An optical method to determine the dynamic parameters of the transient response of an engine injector during its opening has been presented in this article. The method is based on measuring the transparency of a space into which the fuel is injected. The transparency measurements are realised by an optical instrument, which consists of both a transmitter and a detector oflR. radiation. A pair o...
