Fast shutter no longer bouncing open again

We triggered the fst shutter a couple of times by lowering the threshold (i.e. ensuring that the alanog electronics fires the shutter), and wee verified that we didn't see any bounce after 60ms to 100ms (as loged before in alog 28958 ).

Attached are plots for one trigger, on different time scales.
