When the calutron was first operated on 2 December 1941, just days before the Japanese attack on Pearl Harbor brought the United States into World War II, a uranium beam intensity of 5 microamperes ( ?A ) was received by the collector.

The design is based on criteria that allow operation at very high beam intensities : an open structure of four large and powerful RF-cavities providing a high acceleration voltage, and a flat-top cavity operating at the third harmonic of the accelerating RF-voltage.
33.
Circular electron accelerators fell somewhat out of favor for particle physics around the time that SLAC's linear particle accelerator was constructed, because their synchrotron losses were considered economically prohibitive and because their beam intensity was lower than for the unpulsed linear machines.
34.
The distance is calculated from the square root of ( the beam intensity in candelas divided by 0.25 lux ); for example, a beam intensity of 1000 candelas produces a working range rating of the square root of ( 1000 / 0.25 ), or 63 meters.

The microwave beam intensity at ground level in the center of the beam would be designed and physically built into the system; simply, the transmitter would be too far away and too small to be able to increase the intensity to unsafe levels, even in principle.
37.
This demonstrates that tissue heating is proportional to intensity, and that intensity is inversely proportional to the area over which an ultrasound beam is spread therefore, focusing the beam into a sharp point ( i . e . increasing the beam intensity ) creates a rapid temperature rise at the focus.
38.
In this context, the " absorption coefficient " measures how quickly the beam would lose radiant flux due to the absorption " alone ", while " attenuation coefficient " measures the " total " loss of narrow-beam intensity, including scattering as well . " Narrow-beam attenuation coefficient " always unambiguously refers to the latter.

The new Touareg features a world first in automotive headlight technology : the " glare-free high beam " . ( " Dynamic Light Assist " The beam pattern changes its direction continually so that vehicles in front are not being illuminated, while the area surrounding them is being constantly illuminated at high beam intensity.
40.
The number of atoms that would be produced would be approximately equal to the product of the number of atoms of target material, the target's cross section, the ion beam intensity, and the time of bombardment; this last factor was related to the half-life of the product when bombarding for a time on the order of its half-life.
