Optimization of Process Parameters of Electron Beam Welded Fe49Co2V Alloys
Electron beam welding has shown a remarkable job in the space industry for welding of components. It is performed under a vacuum environment that eliminates foreign matter such as hydrogen, oxygen, and other gases. Joining of similar and dissimilar materials is the main advantage of electron beam welding with high depth to width ratio as well as sharp focus at the point where parts are to be we...
متن کاملinvestigation of effective parameters on the rigidity of light composite diaphragms (psscb) by fem
در این رساله با معرفی سقف های psscb متشکل از ترکیب ورق های فولادی ذوزنقه ای و تخته های سیمانی الیافی به عنوان سقف های پیش ساخته (سازگار با سیستم سازه ای قاب های فولادی سبک) به بررسی پارامترهای موثر بر صلبیت سقف، پرداخته می شود. در تحقیق حاضر ابتدا به مدل سازی دو نمونه سقف آزمایش شده، به روش اجزاء محدود با استفاده از نرم افزار تحلیلی abaqus ver 6.10 پرداخته شده است. نمونه های ساخته شده تحت اعما...
IF 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 کاملOptical Response of Strained- and Unstrained-Silicon Cold-Electron Bolometers
We describe the optical characterisation of two silicon cold-electron bolometers each consisting of a small (32 × 14 μm) island of degenerately doped siliconwith superconducting aluminium contacts. Radiation is coupled into the silicon absorber with a twin-slot antenna designed to couple to 160-GHz radiation through a silicon lens. Thefirst device has a highly doped silicon absorber, the second...
متن کاملIF 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 ...
