[Primexd] [EXTERNAL] PrimEx-eta Daily Run Meeting @ 4PM

[gasparan at jlab.org]

  Hi Drew and All,

 We (Liping and me) had a "meeting at 4 pm and suggesting that
 (a) the results from Drew are very promising for the identification of
 Compton events without knowing the initial beam energy; (b) we may
 wait before Drew comes up with simulations results; (c) we discuss them
 in tomorrow's 4 pm meeting and discuss the option of keep running the
 same way only take some good statistics with the B=0 field;

 Drew, you should be able to have one more cut criterion using the two
 clusters energies and angles, please try to find it from kin-cs book.
 With that your cuts should be"
 1) two clusters only with each more than some energy;
 2) sum of two cluster energy is in an interval, say [1-2], [2-3], ...
 3) coplanarity dist-n;
 4) this is one more, new by using the 2 energies and 2 angles.

 Thanks,
 Ashot
