The Ushiwaka magnet and B-field tests
Nitrogen laser near the output. Two fiber optic cables are seen.
One goes to a trigger PMT (H1161),
and the other goes to a piece of
scintillator (1 by 1 by 3 cm) facing fine-mesh PMTs to be tested.
Fine-mesh PMT holders for B-field tests. With and without a cap,
which houses the scintillator piece inside
and has a fiber optic connector outside.
