Direct Measurements of ne Flux

1. A clever way to constrain ne's from KL's (KL®ne e p)
- KL®nm m+ p- and KL®nm m- p+ too.
- And these happen in both n and n SSQT configurations. So KL®nm m- p+ puts nm's into the nm beam!
- These are easy to spot!
2. Shower shape analysis can statistically pick out n events
(80 < En < 180 GeV)
