The idea is to change the cables to have individual signals. This will allow 4 thermocouple readings.

The p2n target was taken out of the test stand for inspection. Comments and measurements on the container below:
- Initially, continuity measurements were mode between the target and heat shield (HS) while they were still in the test stand, and looks like
they were shorted. However, after removing the HS from the test stand, no short was seen, not even after moving the target legs. Instead, we confirmed |
