MINOS

1: Particle ranges from simplest Cov selection (1.8 GeV)

Simply by asking for both covs fired=muon (top left), neither fired=pion (top right), only the first fired=presumed muon (bottom left), only the third fired=presumed muon (bottom right).

2: Particle ranges superimposed (1.8 GeV)

Simple ps muon cut: anything hitting plane >=58 or edge strips of 57.
Note: Pion and muon peak significantly displaced.

3: Fit to muon peak

MC says about 51.2...

4: Fit to muon peak in other covs

5: Cerenkov threshold pressures

At 1.8 GeV, 4.2 atm is right on the edge...

6: Plane cut to remove electrons

But shouldn't really cut on range when that's what you're measuring...

7: Electron removal

(Number of hits in event) / Number of planes hit -> (1.9 >= multiplicity cut <= 2.45)

8: X-Projection of multiplicity

9: Cov Cut (2 GeV)

Electrons and PS muons deposit lots of energy in the Covs...

10: Cov Cut

155 entries remaining after multiplicity cut...

11: No electrons

... none of which are consistent with electron range -> multiplicity cut very effective!

12: 1.8 GeV

Different muon peaks may indicate that only the muons in the high energy tail are firing both covs...

13: 2 GeV

6 muons expected in pion peak... Strangeness in Cov 3 must be pions...Marked change in Cov1 efficiency due to cov threshold again?
