Subject: parasitic target commissioning 

 2021-04-04 16:07 New container is in with heatshields, vacuum 8.6E-6 torr. leak check done. ramping up current, checking both pyrometer and TC, 1A/10s.

 2021-04-04 16:49 200A TGHT 250degC on TC 1130degC on pyrometer. Too low on TC, ramping down and venting to reposition TC in the foil. 

 2021-04-04 18:00 TC was slightly broken, repaired now. Pumping chamber.

 2021-04-04 18:41 ramping up to 200A 1A/10s.

2021-04-04 18:41 200A TGHT, TC 389degC pyro 1130degC. ramping to 400A 1A/10s.

2021-04-04 18:41 300A TGHT, TC 554degC pyro 1440degC. 

2021-04-04 18:41 400A TGHT, TC 735degC pyro 1720degC. ramping to 600A 1A/10s. 

2021-04-04 20:15 500A TGHT, TC 891degC pyro 1990degC

2021-04-04 20:15 553A TGHT, TC 975degC pyro 2129degC, ramping down.

2021-04-06 13:44 Parasitic target plus thermocouples were introduced in evap2 the day before and put under vacuum. IG1 3E-7 torr, leak check done. Putting some power into HE while ramping up container to 100A 1a/10s.

2021-04-06 14:06 20W on HE 100A on target container. Everything stable. Ramping up to 200A 1A/10s 

2021-04-06 14:06 20W on HE 200A on target container. Everything stable. Ramping up to 300A 1A/10s 

2021-04-06 14:06 20W on HE 300A on target container. Everything stable 4.6E-7 torr. Ramping up HE to 40W.

2021-04-06 14:06 40W on HE 300A on target container. Everything stable 4.6E-7 torr. Ramping up container to 400A 1A/10s.

2021-04-06 14:06 40W on HE 400A on target container. Everything stable 1E-6 torr. Ramping up container to 500A 1A/10s.

2021-04-06 15:52 35W on HE 500A on target container. Everything stable 1.6E-6 torr. Ramping up He to 65W.

2021-04-06 18:40 at 50W on HE one of them broke, system ramped down, vented, HE replaced, pumping down system again.

2021-04-07 10:38 HE at 70W, ramping up container to 200A 1A/10s. Vacuum 3.3E-7 torr.

2021-04-07 10:59 HE at 70W, 200A on container, ramping up container to 300A 1A/10s. Vacuum 3.9E-7 torr.

2021-04-07 10:59 HE at 65W, 300A on container, ramping up container to 400A 1A/10s. Vacuum 4.5E-7 torr.

2021-04-07 11:50 HE at 70W, 400A on container, ramping up container to 500A 1A/10s. Vacuum 7.8E-7 torr.

2021-04-07 11:50 HE at 65W, 500A on container, ramping up container to 553A 1A/10s. Vacuum 1.4E-6 torr.

2021-04-07 11:50 HE at 65W, 553A on container. All good, ramping down. 1A,10s.
