<p>Hall B TL 4K supply circuit was fully warmed. 51F minimum temperature was recorded 1/16/25. No significant contamination was recorded even though the circuit went sub-atmospheric ~6 times during the SAD (SAM). 2024.</p>
<p>Cooldown of the TL and piping in the Torus and Solenoid starting now using LN2 cooled helium.<br>
The plan for tomorrow 1/21, is that Cryo will be installing the 4K supply U-tube and 4K cooldown will commence.</p>
