x-ray tube

n.
A vacuum tube containing electrodes that accelerate electrons and direct them to a metal anode, where their impacts produce x-rays.

X-ray tube

n
(General Physics) an evacuated tube containing a metal target onto which is directed a beam of electrons at high energy for the generation of X-rays

x-ray tube


n.

However, like a dimmer switch on a household light, you cannot continue increasing this indefinitely without "burning out" the "bulb." Therefore, the x-ray tube is limited to a maximum target current.
A new business pipeline and strong forward order book give a positive outlook for revenues and demonstrate that customer demand for the existing CT X-Ray tube product portfolio continues to be robust.
Thus, it is necessary to control the DC output voltage across the X-ray tube over widely-specified voltage setting ranges by using high-power DC-DC converter.
"We currently employ nearly 900 people in Utah, building over 50,000 flat panel detectors and x-ray tubes each year.
While one robotic arm moves the X-ray tube, the other arm carries the 17" x 17" flat panel detector, which can acquire static, dynamic, and Real 3D sequences.
The company also offers service and installation of X-ray tubes in public hospitals, including capacity to refurbish and restore medical parts with CE marking, quality assurance consulting and the sale of refurbished systems and conventional X-ray tubes.
* The differences in dose to the neurosurgeon with the X-ray tube either above or under the table were compared.
PANalytical says the performance of the Epsilon 3 comes from selective excitation and careful matching of the x-ray tube output to the capabilities of the detection system, together with "advanced spectrum processing and unique correction and quantification algorithms".
However, because of the density variation between tin, copper and silver predominant in Pb-free alloys, it is recommended that certain x-ray tube parameters be adjusted when inspecting Pb-free BGA and chip-scale package devices to ensure optimal image contrast and enhanced analysis.
The high level of performance results from the inclusion of advanced electronics combined, in the XL3t, with a new powerful state-of-the-art x-ray tube. The XL3 series comes in a range of configurations and with optional features and accessories.
The low-power x-ray tube reduces heat production and eliminates the need for external cooling for increased reliability and reduced maintenance costs.
Sample manipulation in the x, y and z directions within the x-ray inspection system is necessary to permit movement to different locations on the test sample (x and y-plane movements) and to change the height of the sample relative to the x-ray tube position (z-direction).
