The intention is to keep the fridge in production mode for a sustainable polarization study. To perform sustainably polarization studies, we have to keep the polarization at maximum. After reaching maximum polarization, we will turn off the microwave, and when the polarization curve starts decaying down, we will again turn it on. The power cycling of microwaves helps us reduce liquid helium consumption.
For the sustainable polarization studies, the liquid level in the fridge should be at the Heat-Ex bottom and kept there during the Production Mode.
→ What if the liquid level drops from the Heat-Ex bottom:
If the liquid level in the fridge drops from the Heat-Ex bottom, then open the Run valve on the following
