Determination of the Pulsed Electron Beam Spectrum by Current and Voltage Oscillograms

“…To record the electron's distribution after moving half a circle driven by Lorentz force, an imaging plate was placed perpendicular to the incident direction of the electron beam by the side of a 1 mm diameter collimator hole. e energy spectrum of the pulsed electron beam generated by the directaction accelerator is calculated from the accelerating voltage and electron current oscillograms [12]. At an electron energy of more than 10 keV (speed exceeds 6 cm/ns), the delay between the oscillograms of accelerating voltage and the electron current is insignificant, even at a distance of 5-10 cm from the diode to the electron current sensor-Faraday cup (FC).…”

Scanning Horn Simulation Code for Electron Beam Machine Based on Boris Algorithm

“…In Ref. [10], a beam simulation code package specifically made for the scanning magnet of an electron beam machine is proposed. The method uses integer steps for both position and velocity (or momentum) updates.…”

“…Several authors have pointed out that non-symplectic methods with same step evaluation between position and velocity such as in Ref. [10] or fourth order Runge-Kutta method will not be as accurate as staggered time algorithms such as Boris method [11,12], especially after a long period of time. There is also another simulation code applied to similar type of machine called electron beam welding [13].…”
