2020-10-09 9:48 The target was installed the day before and left pumping over night. IGP1=4.7e-7Torr. leak check when water on, ok. Setting ramp
up
2020-10-09 10:16 Ramping up the target to 50A, 1.5A/30s. All good. Going to 200A same rate. |

Tantalum samples were loaded in a tantalum testing tube and installed in the EVAP2 to heat under vacuum for 3 days at 2000 degC (~500A, 4kW).
The temperature is measured with the Omega pyrometer (slope 0.98) |
