2021-03-30 7:48 Target loaded with parasitic target only. No container. Leaving under vacuum over night.

 2021-03-31 13:43 Leak check performed. Water on. Need to vent system, electric connection disconnected.

 2021-03-31 15:02 First test successfully finished. Venting to introduce container with radiating heating gun.

 2021-04-01 14:58 Vacuum 3.5E-7 torr. Leak check done. Ramping up target heater to 100A at 1A/10s

 2021-04-01 14:58 Vacuum 5E-7, 100A all ok. Temp foil 24.3DegC. ramping to 500A at 1A/10s.

 2021-04-01 14:58 Temp of foil not increasing much. Probably issue with TC. ramping down at 1A/10s to vent and inspect.

 2021-04-02 11:03 Target reinstalled, foil TC reinstalled. Vacuum 3E-7 torr. Leak check done. Ramping up container to 500A 1A/10s. 

 2021-04-02 13:07 Still isues with TC. Container ramped down at 1A/10s. Venting, brought heat gun to check TC.

 2021-04-02 15:10 TC connection fixed, origin of issues. Vacuum down to 3E-5 torr. Ramping up container to 200A 1A/10s.

 2021-04-02 18:32 TGTH 200A Tc temp 327.5degC. ramping up to 300A. 1A/10s.

 2021-04-02 18:32 TGTH 300A Tc temp 500degC. ramping up to 400A. 1A/10s.

 2021-04-02 19:17 TGTH 400A Tc temp 618degC. ramping down.

 2021-04-03 13:37 Foil was changed, ramped up to 200A at 1A/10s, Temp TC 360degC. Ramping to 300A. Vac 8.6E-6 torr.

 2021-04-03 13:59 300A Temp TC 580degC. Ramping to 500A, 1A/10s. Vac 7.6E-6 torr.

 2021-04-03 14:36 500A Temp TC 836degC. Ramping to 600A, 1A/10s. Vac 9E-6 torr.

 2021-04-03 14:36 600A Temp TC 960degC. Vac 1.1E-5 torr. Ramping down. 

2021-04-03 19:00 After venting an opening the evap2, it was found that remaining from a past heat treatment where on the Tantalum container. The sublimation of the material coated the inner walls of the evap.2. Now cleaned.
