keyword=Note on max. current for He4 target.
We noticed that while running at 60uA current on the He4 target at this temperature (7.50K) and pressure (~200psi), we had about 60W available heater capacity, with a CHL flow between 19.5 and 20.0 g/s. Given this, I do not think it is a good idea to go above 65uA on the beam current.
