The same p2n target was installed in the test stand, taking off the ion source since we thought it could have been shorting to the reference electrode and providing a return path for the current, hence generating the asymmetric heating that was noticed on the target.

On Tuesday 6th afternoon, the p2n was ramped up to 600 A (300 + 300 A from TGHT and TBHT in parallel). The target and its right flexible leg were still glowing. After noticing it, the current was ramped down wating to open up for inspection.
