Electron Accelerator

The electron accelerator has a dual beam system which supplies either vertical or horizontal beams.
Specification of the electron accelerator.
Acceleration Type Acceleration Voltage (MV) Beam Current (mA) Scanning Width (cm) Scanning Frequency (Hz)
Cockcroft-Walton 0.5–2 0.1–30

Vertical: 120

Horizontal: 60

Depth-Dose Distribution

The below figure shows depth-dose distribution of electron beams in water, which is compared with that of Co-60 gamma rays. The dose rate is normalized by each maximum value.
