fairly quiet night of emphy target data taking with reversed polarity power supply.

one of the LADS (L15_R1 bottom) trips constantly. it has been set to zero.

also, WC box R11 started tripping constantly (both the sense and field simultaneously). maybe a broken wire???

also, WC box L21 has started tripping fairly often again. it's a funny trip, too. first, the guard wire starts to oscillate increasingly about 1900V. eventually the oscillations get too big, and the guard trips, which immediately brings down the sense, too.
