Last two rounds of materials in evap1 have tripped off the TGHT in epics within minutes of the target reaching 520A.

Loaded an empty target boat, no heat shields.

Will ramp up with same speed as last two samples to see how TGHT reacts and whether a trip is induced or not.

Currently pumping down now.
