Computer Simulation of Runaway Electrons in the Iran Tokamak 1 (IR-T1)

In the present work we study the dynamics of runaway electrons circulating in ohmic plasma of the Iran - Tokamak 1 (IR-T1). In this study, test electron in momentum space including the acceleration in the toroidal electric field, collisions with the plasma particle and deceleration due to synchrotron radiation losses is done. We calculate critical normalized momentum by normalized electric field in ohmic plasma discharge in IR-T1 and the critical energy for the runaway electrons describing the two contributions to the radiation losses coming from the guiding center motion and the electron gyro-motion.
