Niowave Pb-Bi target
Pb-Bi liquid target operation
1.) pump down chamber 2.) backfill with argon to 1atm 3.) heat top at full power by plugging into wall directly, the other heaters use a rheostat 4.) 360 watts applied to mid center until temperature at bottom flange is 120 C 5.) turn on the other heaters at 20 % of 120 volts until the temperature warms to at least 40 C 6.) vent if the pressure go above 2 ATM 7.) once loop is about 40 C or more, increase rheostats to 40% of 120 volts 8.) top reservoir will be kept heating at full power until maxing out at 300 C then you can turn it off when bottom well is liquid 9.) at 70 C in the well increase reostat to 60% 10.) unplugged top heater when it hits 289 C, temp in middle of loop was 280 11.) when well temp was 170 C , the high power heater (right side) is increased to 100 % while all other heaters are turned off 12.)
Once well is the hottest you can turn off top reservoir heater
20 C difference between top center and well right
4 = top center 3=center left 2 = well right 1=well left
