Niowave 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 goes 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
20 C difference between top center and well right
4 = top center 3=center left 2 = well right 1=well left
