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 that the short was happening in the test stand, so some water lines were touching each other.
- The target look in one piece, except for the ion source that came off right after manufacturing. (see picture)
- The insulator connecting the bottom section of the ion source central current lead, to the HS, was broken (see picture)
- The annular disc of the connecting the inner and outer tube of the ion source was bulging outwards, maybe the ion source was heating too much while we put current in it (see picture).
- The screw connecting the top part of the central ion source current lead, is now of a blue-ish color
