Electron beam welding (EBW) is a fusion welding process in which a beam of high velocity electrons is applied to the materials being joined. The workpieces melt as the kinetic energy of the electrons is transformed into heat upon impact. Electron beam welding (EBW) is used mainly for fabricating structures that have stringent quality, strength, and joint reliability requirements. This process has been applied in aerospace, shipbuilding, defence applications and instrument manufacturing. EBW p
An electron microscope uses high energy electrons rather than light (which is used in conventional optical microscopes), to form an image. A thin beam of high energy electrons is produced and bombards the specimen thus producing scintillation which is captured and measured though a scintillation counter. Since the electron beam scans the specimen line by line and builds the image, it is called a scanning electron microscope. The advantages to using the SEM in-place of an optical microscope ar
Medical X ray systems are pretty common now-a-days. We see those in all hospitals, big or small. Do you know that most of these X-ray systems are powered by line frequency generators and thereby emit lot of unwanted radiation?
Before you get alarmed, let’s understand the basics.
An X ray system typically has two main components. One is the X Ray Tube (for generating the rays) and the other, a specialized power supply for supplying the required high voltage to the tu
