keyword=RICH Freon LeakTo verify, that there is a freon leak from the radiator into
the wire chamber area, we emptied the radiator last night.
After that the wire chamber draw significant current (purple)
when the beam was on. This morning we refilled the radiator
with freon (brown curve), and immediatly the wire chamber drained
less current. Replay of the data also shows, that the gain
of the wire chamber increased during the absence of freon to
normal values, and dropped immediatly (minutes) after refilling
the radiator.
