The construction project of linear accelerator was start in 1974. The main research program in the use of this linear accelerator is to obtain data needed for picosecond pulse radiolysis.
A new system, so called “TWIN LINAC SYSTEM”, was developed 1984. The system consists of two linear accelerators. The highly advanced control system was needed for the synchronized operation of the two linear accelerators.
The characteristics of a grid modulator for short pulse beam (10 picosecond) using varactor diode are described.
