| Summary: | The project consists of three stages. The fust stage demonstrates, through
experimental works on the highvoltage deck of electron beam accelerator unit; filament
control circuit board and beam control circuit boards. In these circuit boards, an analog
signal flows from low voltage sides via optical link cable to the ground and transmitted
to the highvoltage side. The calibrations were made to ensure its safe operation. The
second stage was to generate a new method of filament control and beam control circuit
by constructing a Programmable Logic Controller (PLC) using the STEP 7-
MicroIWIN32 and SIMA TIC WinCC software provided by SIEMENS AG. It is capable
to operate under a highvoltage potential. It uses a PROFIBUS technology as the central
connecting link for digital signal flow in the system. The advantages of the digital
solution are the speed of data transmitting in both directions are faster and better signal
to noise ratio (SNR) than analog solution. Finally, as the circuits in both projects were
operated under a highvoltage potential, there would be a conflict with the transient
voltage upon the components, equipments and cables installed in the circuits. Therefore,
in the third stage, one circuit protection was created and examined to show transient
voltage fault investigation methods and possible solutions. At the end, the project is
attempted to expand the automation technology in highvoltage area and support future
development in this area |
