Gerardo and I started the long process of leak testing new conflat joints on the H1 input MC volume. Gerardo found a 6.1 x 10-7 torr*L/sec leak on HAM3 lower SW (1)12"x(3)4.5" feed-through (leak on 12" joint). Much more hunting in the next few days. Also, I accidentally shut of the instrument air to the safety valve on the YBM MTP and had to restart the MTP shortly after it began to spin down.
