3. Exposure ~ km2-yr
2.3 x PRL
Zenith angle ≤ 600

4. ~20 events/year ->

5. Ralph Engel

6. Several events per source
Auger North - 10 yr
~1,400 events E > 60 EeV
Several events per source
Auger South – 10 yr
~200 events E > 60 EeV

8. 1 PMT per tank

9. Apertures & Energy Threshold

Apertures & Energy Threshold
Auger North
Anisotropies 9

10. Angular resolution basically depends
on number of triggered tanks.
Evaluate from real events excluding tanks
to approximate a sparser array
Do a Monte Carlo Simulation

11. Ioana Maris

15. R & D array in Lamar Colorado
10 tanks
Technical Issues:
Single PMT (checked in south)
Insulation of tanks
Communications
