keyword=Target operation T increased to 8.1K.
Par Makis' request, I increased the operating temperature to be able
to handle ~80 uA. A rough estimation, we will need ~480 watts beam
power plus 30-40 watt HP heater for stability. SO I increased T from
7.5 to 8.1K when total HP heater power reached ~520 watts, while CHL flow kept at 19.8 g/s. I bleed out some He4 gas to keep the pressure at ~200 psi (204 psi). We should be just about enough for 80 uA.
