    keyword=100uA on LD2 target

    We are currently running 100uA on the LD2 target. The JT valve is 40.4% opened, and the HP heater provides 50W extra watts of heatload. This is the maximum the HP can run to compensate such a beam. In this configuration, it takes ~50 seconds for the target temperature to go from its max (22.3K) back to 22K after a beam trip.

    Therefore, I suggest that if the beam trips too often (more than 1 trip every 2-3 minutes), we should lower the current so that the beam is more stable.
