- Generation of X-Rays
The x-ray tube current (mA) determines the x-ray flux rate (photons per square cm per second) emitted by the x-ray tube at a given kVp mAs = mA x sec (exposure time) Low mA selections allow small focal spot size to be used, and higher mA settings require the use of large focal spot size due to anode heating concerns
- PowerPoint Presentation
Small computer speakers often have power supplies that give 12 V at 200 mA How much charge flows through the circuit in 1 hour and how much energy is used to deliver this charge?
- DOCUMENT TITLE SECOND LINE AND THIRD LINE - Purdue University
X-ray production is proportional to operating potential (kVp) and current (mA) When the X-ray unit is not operating or it is powered down, the high voltage is not applied and X-rays are not produced Therefore, there is no danger present when the machine is not operating or it is powered down
- ELEC7770 Advanced VLSI Design Spring 2007 - eng. auburn. edu
Propose a scheme for delivering power to different parts of a large integrated circuit, such as cores on a system-on-chip (SoC), at a higher than the regular (VDD) voltage The increase in voltage will lower the current on the grid, and thereby reduces the I2R loss in the on-chip power distribution network
- Radiation Safety Training Washington State University . . .
Accelerated charges give off electromagnetic radiation, and when the energy of the bombarding electrons is high enough, that radiation is in the x-ray region of the electromagnetic spectrum
- BASIC ELECTRICAL SAFETY
Burns can result when a person touches electrical wiring or equipment that is energized ARC-BLAST Arc-blasts occur from high- amperage currents arcing through the air This can be caused by accidental contact with energized components or equipment failure
- DRIVEN SUBCRITICAL FISSION RESEARCH REACTOR USING A . . .
Instead, higher beam currents and improved ion recirculation are key; other special crucial issues include high-voltage stand-offs that are “radiation hardened”
