Study forward detector gamma flas with Pb curtains

Thorium strip, collimator squeeze down.

No target run

Determine how many fissions per pulse.

run 1 mg HEU to see (probably miserable) rates

Exploratory measurements with 47% HEU.

CFD studies

P.S. sweep magnet in/out

Long run on Thorium

Long run on 1 mg HEU
