    Hall A cooldown has begun using the heat exchanger. All magnet N2 valves are closed. All N2 is being routed through the heat exchanger. An additional vent was opened to reduce the heat exchanger output temp. A single vent does not apppear to be enough to maximize heat exchanger efficiency. Robert Norton installed calc records to compute temp deltas on each magnet GUI. The signals will be used in the valve PID loops to automate temp delta control on individual magnets.
