Elastic scattering

• 5-50 MeV, 5 MeV intervals
• ve, vbare, vμ,τ, vbarμ,τ
• 500 events each
• Slow detsim

Elastic scattering study

• True physical

pointing resolution - from angle between true e direction & true v direction

Pointing Resolution vs Electron Energy

Elastic scattering - supernova distribution

• ES events from supernova

flavor and energy distribution

• Range of numbers of events

corresponding to supernova distances

• Pointing resolution for

supernovae as function of number of events

• Future: other interaction

channels
