Salehinia Laser and Optics Research School, Nuclear Science and Technology Research School, Atomic Energy Organization of Iran, Tehran, Iran Physics Department, Alzahra University, Tehran, Iran Laser and Optics Research School, Nuclear Science and Technology Research School, Atomic Energy Organization of Iran, Tehran, Iran Two gold vapor laser tubes with different lengths of 60 and 75 cm and identical diameter of 16 mm were used to investigate the behavior of inverse voltage on thyratron’s anode in the excitation circuit, versus operationl parameters such as buffer gas pressure and electrical input voltage. It was shown that, the inverse voltage on thyratron’s anode decreases with increasing of the buffer gas pressure and so electrical input voltage, individually. By optimization of these operational parameters, the lifetime of thyratron will be increased. 03 2012 6 8 10.14331/ijfps.2012.330025 https://www.fundamentaljournals.com/index.php/ijfps/article/view/26
