A beam current, for example, of one ampere at 5 million electron-volts would produce beam power of 5 megawatts, the equivalent of 5,000 electric cooking range surface units of one kilowatt each.
Also, set accelerating voltage and beam current precisely to get reproducible results.
The extracted beam current is 400 microamperes and can be extracted simultaneously in any split ratio from two extraction ports on opposite sides of the cyclotron.

3--this is attributable to a lower moderator brightness as well as a lower production beam current in reality, as compared to initial forecasts when the LANSCE upgrade and the NPDGamma experiment were first proposed.
Accelerating voltage can be varied to change the energy content of each electron, or beam current can be manipulated to control the total number of electrons in the beam.
The maximum penetration depth (the electron range) depends upon a lot of factors: electron beam current, accelerating voltage, electron beam diameter, electron beam power, material density, etc.
To remove those contributions, the data and background runs were normalized to the beam current and separate variances were calculated for each group of 20 macro pulses and then averaged.
The goal is to produce high beam current, on the order of 100 times that of a conventional synchrotron, for perhaps 100 turns.
