Pressure down to 7.1e-7 Torr. Water valve to heat shield was opened; pressure remained stable.
Current turned up to 40 A for now. Will increase at 2 A/min up to 500 A over the weekend, then on Monday we will turn it up to 600 A and
check the temperature. |

Auto-ramp started. Max current = 500 A, voltage = 11.05 V. Current is being increased at 2 A/min. In the first 20 minutes, the pressure went up to about
10E-6 T, but has slowly decreased since then. Everything looks ok. The system will be left until Monday morning (June 9th). |

Manually changed current from 500 to 615 A, monitoring the temperature. Temperature went from 1657 C up to 1838 C. Pressure increased up to 7.2e-7 T.
Samples should be left for about 4 hours (615 A started just before 13:00), then the goal is to ramp current back to zero. |

The target container end caps were coated with TaC spray and let dry.
The caps are inserted in the target boat wrapped in graphite foil with 3 x Ta-heat shields. |
