We present 2D resistive MHD simulations of the MARZ platform using GORGON, which includes realistic cooling curves and separate ion and electron energy equations. In these simulations, a current sheet develops with a Lundquist number ∽800, containing plasmoids generated by the tearing instability. As the drive strength increases, the layer density and the radiative cooling also increase, leading to a rapid loss of thermal energy within the current sheet. This triggers a sudden collapse of the layer, quashing the plasmoids and stalling the reconnection process. We use the XP2 code to post-process these simulations, enabling photometric predictions for synthetic diagnostics at the Z facility.
