LN2 storage tank should have 10 minutes of operation at .45 T magnet intensity. Capability to install a larger tank as experiments warrant.
Storage at 150 psig except when operating reactor then storage will be at 0 psig. Liquid level measurement will be a differential pressure gauge on the pump inlet standpipe (safety).
Total liquid level measurement will be a teflon insulated probe capacitance measurement. The probe will extend through the tank and down the standpipe to near the pump inlet level.
