continued taking "bump" data with emptry target. finished taking data for (H, V) = (+1.5mm, 0.0mm) and also took data for (H, V) = (0.0mm, +1.0mm); see runs 2947, 2949-2954 and the elog entries. ccr had some trouble (about 2-3 hours worth) tuning for the latter beam setting.
switched the chambers' helium gas cradle. L21 was fairly quiet, but L00 tripped regularly.
there exists some question as to whether the unpolarized gas feed system is disconnected from the storage cell. if so, then high-current data with an empty target should be taken. if not, then more unpolarized hydrogen data should be taken.
