IF Impedance and Mixer Gain of Hot-Electron Bolometers
We have measured the frequency dependent IF impedance and mixer conversion gain of a small area NbN hot-electron bolometer (HEB). The device used is a twin slot antenna coupled NbN HEB mixer with a bridge area of 1 μm x 0.15 μm, and a critical temperature of 8.3 K. In the experiment the local oscillator (LO) frequency was 1.300 THz, and the intermediate frequency (IF) 0.05-10 GHz. We find that ...
متن کاملIF impedance and mixer gain of NbN hot electron bolometers
The intermediate frequency IF characteristics, the frequency dependent IF impedance, and the mixer conversion gain of a small area hot electron bolometer HEB have been measured and modeled. The device used is a twin slot antenna coupled NbN HEB mixer with a bridge area of 1 0.15 m2, and a critical temperature of 8.3 K. In the experiment the local oscillator frequency was 1.300 THz, and the IF 0...
متن کاملAllergenic potency of spices: hot, medium hot, or very hot.
Spices are the most attractive ingredients to confer an authentic taste to food. As they are derived from plants, they harbour allergenic potency and can induce symptoms ranging from mild local to severe systemic reactions. Due to the content of pharmacologically active substances of spices, the diagnosis of allergy and the differentiation from intolerance reactions may be difficult. Associatio...
متن کاملOptimization of Hot Workability in Ti-IF Steel by Using the Processing Map
Processing map for hot working of Ti-IF steel has been developed in the temperature range of 750 to 1100 °C and strain rate of 0.01 to 100 s-1. This map in the austenite region exhibits a single domain with a peak efficiency of 45% occurring at 1025 °C and strain rate of 0.02 s-1. The domain extends over the temperature range of 1000 to 1100 °C and strain rate range of 0.01 to 1 s-1. The true s...
متن کاملEffect of Composition on the Recrystallization Behavior of if Steels During Simulated Hot Strip Rolling
Flow curves are generated in muti-pass torsion tests for a titanium stabilized and a niobium stabilized IF steel. Two types of test schedule are used, one based on plate rolling and the other approximating strip rolling. The purpose of the former is to define the three critical temperatures of steel rolling. The strip schedules are varied in order to investigate the influence of increasing the ...
