VSM schematic VSM setup. A vibrating-sample magnetometer (VSM) (also referred to as a Foner magnetometer) is a scientific instrument that measures magnetic properties based on Faraday’s Law of Induction.
With the help of the expert glassblower of the Department, Jake Jonson, I built my first high vacuum magnetron trap in 1959 and was soon able to trap electrons for about 10 sec and to detect axial, magnetron and cyclotron resonances." – H. Dehmelt. H. Dehmelt shared the Nobel Prize in Physics in 1989 for the development of the ion trap technique.
Critically, this magnetoresistive scenario depends sensitively on the device geometry and current lines and it does not rely on magnetic materials. In a semiconductor with a single carrier type, the magnetoresistance is proportional to (1 + ( μB ) 2 ) , where μ is the semiconductor mobility (units m 2 ·V −1 ·s −1 , equivalently m 2 ·Wb ...
The magnetron remains the essential radio tube for shortwave radio signals of all types. It not only changed the course of the war by allowing us to develop airborne radar systems, it remains the key piece of technology that lies at the heart of your microwave oven today. The cavity magnetron's invention changed the world. [5]
In January 2008, ASUS began a major restructuring of its operations, splitting into three independent companies: [8] ASUS (focused on applied first-party branded computers and electronics); PEGATRON (focused on OEM manufacturing of motherboards and components); and Unihan Corporation (focused on non-PC manufacturing such as cases and moulding).
The electric field and the resulting axial harmonic motion reduces the cyclotron frequency and introduces a second radial motion called magnetron motion that occurs at the magnetron frequency. The cyclotron motion is still the frequency being used, but the relationship above is not exact due to this phenomenon.
Crossed-field amplifier internal operation. A CFA's electric and magnetic fields are perpendicular to each other ("crossed fields"). This is the same type of field interaction used in a magnetron; as a result, the two devices share many characteristics (such as high peak power and efficiency), and they have similar physical appearances.
In atomic physics, the Bohr magneton (symbol μ B) is a physical constant and the natural unit for expressing the magnetic moment of an electron caused by its orbital or spin angular momentum.
