Recent Progress in EM-GTS code

In this presentation I will give the overview of the recent progress in the development of the electromagnetic capabilities in the gyro-kinetic PIC code GTS. I will describe the Startsev-Lee EM scheme that is capable of simulating the micro-tearing (MTM) modes and which recently has been extended to the general tokamak geometry and implemented into GTS. Initial attempts to simulate the MTM modes in the core of the NSTX will be presented. We have also implemented the modified Mishichenko’s general geometry EM scheme into GTS for cross-scheme-verification. The EM-GTS is currently being used to study the electromagnetic modes in the pedestal region of the DIIID. The benchmarking of the code in the Cyclone and pedestal DIIID geometry against published results is ongoing to better understand the resolution requirements of the implemented EM schemes.
