Orsay data: looking for coincidences

The data: Run 105 (80 MeV 14C on nat C)
The sort routine: require exactly one good event (i.e. both ends of strip have good signal) in det 1 (downstream), and exactly one good event (i.e. both ends of strip have good signal, and the complementary strip in det 3 does NOT have a signal) in det 4 (downstream quad).

Trying to track which events in one detector match events in another detector.

First gate on a single strip in det 1 and see where corresponding events go in det 4. Here's the strip in det 1...


...and here are the corresponding events in det 4.


Now gate only on a selected bit of that strip in det 1: try to select the most intense part of the locus that I think looks like elastic scattering. Here it is...


...and here are the corresponding events in det 4. The fact that they are show up more in one side of the detector than the other is encouraging. There also do seem to be loci, although I'm not yet sure what to make of them.
