A longitudinal ion and energy transport through the magnetic mirror appears to be the dominant problem in open magnetic traps physics. Cold electrons flow from the field expansion area has been found to be the main mechanism that limits target plasma heating in the central cell of the Gas Dynamic Trap (GDT). One of the dominant cold electrons sources is apparently a residual neutral gas in the expander. Gas and plasma interactions result in gas ionization, and give cold electrons that penetrate through the magnetic mirror into the central cell of the machine. This work aims to find a critical gas concentration in the expander above which it begins to effect basic plasma parameters in the central cell of the GDT. The results obtained from these experiments are crucial for understanding the engineering requirements for the pumping system in divertors of the C-2W machine being built in Tri Alpha Energy Inc. and experimental machines of next generation being designed.
