Measurement of BRIKEN neutron counter efficiency
252Cf source in the (approximately) center
Wasabi and D4 clover inserted. G7 on the floor.
YSO on the box with light pulser.

The source was plug in a Styrofoam piece at the right height
so that it could be centered longitudinally with the D4 Clover
and transversely with the Wasabi nose.
Possible position difference with previous efficiency
measurements using the cardboard source holder
should not impact the efficiency obtained.
