Element Electronics is a private company specializing in the sale of affordable televisions, monitors, soundbars, and a diverse range of appliances. Founded in 2007, the company is headquartered in Winnsboro, South Carolina. Element Electronics has expanded its presence, with additional offices located in Minnesota, Arkansas, and Georgia.
With high count rates or slow detectors (MCPs with phosphor screen or discrete photomultipliers), pulses overlap. In this case, a high impedance (slow, but less noisy) amplifier and an ADC are used. Since the output signal from the MCP is generally small, the presence of the thermal noise limits the measurement of the time structure of the MCP ...
A plasma display panel is a type of flat-panel display that uses small cells containing plasma: ionized gas that responds to electric fields. Plasma televisions were the first large (over 32 inches/81 cm diagonal) flat-panel displays to be released to the public. Until about 2007, plasma displays were commonly used in large televisions.
If the magnetic field in the plasma is not stationary, either because the plasma as a whole is transient or because the fields are periodic (radio-frequency heating), the rate of change of the magnetic field with time (˙, read "B-dot") can be measured locally with a loop or coil of wire.
The filter and demodulator separates the 45.75 MHz video from the 41.25 MHz audio then it simply uses a diode to detect the video signal. After the video detector, the video is amplified and sent to the sync separator and then to the picture tube. The audio signal goes to a 4.5 MHz amplifier. This amplifier prepares the signal for the 4.5 MHz ...
A minimum detectable signal is a signal at the input of a system whose power allows it to be detected over the background electronic noise of the detector system. It can alternately be defined as a signal that produces a signal-to-noise ratio of a given value m at the output. In practice, m is usually chosen to be greater than unity.
Indirect detectors contain a layer of scintillator material, typically either gadolinium oxysulfide or cesium iodide, which converts the x-rays into light.Directly behind the scintillator layer is an amorphous silicon detector array manufactured using a process very similar to that used to make LCD televisions and computer monitors.
Hybrid pixel detectors are a type of ionizing radiation detector consisting of an array of diodes based on semiconductor technology and their associated electronics. The term “hybrid” stems from the fact that the two main elements from which these devices are built, the semiconductor sensor and the readout chip (also known as application-specific integrated circuit or ASIC), are ...
