1. Sean Grullon Waveform-Based Reconstruction for EHE Cascades

2. Oxford Workshop September 21 st - 24 th, 2005 Oxford September 2005 Sean Grullon2 Overview Use of wf-llh-reco reconstruction module for EHE cascade events Current EHE analysis plans Future Directions for EHE reconstruction

3. Oxford Workshop September 21 st - 24 th, 2005 Oxford September 2005 Sean Grullon3 Using Wf-llh-reco for EHE cascade events EHE events ideal for waveform reconstruction Reliable energy reconstruction crucial – Energy reconstructed at the same time as vertex. Good PDF taking into account the depth-dependent ice properties very important Non-contained events extremely important during early stages of deployment

4. Oxford Workshop September 21 st - 24 th, 2005 Oxford September 2005 Sean Grullon4 Preliminary Results for an initial study of non-contained events 500 JULIET Toy Cascades simulated with layered photonics tables. Cascades simulated from 1PeV to under 10EeV All cascades non-contained, randomly distributed from just outside full Icecube array to 0.5 km away.

5. Oxford Workshop September 21 st - 24 th, 2005 Oxford September 2005 Sean Grullon5 Non contained EHE events: Preliminary Energy Resolution

6. Oxford Workshop September 21 st - 24 th, 2005 Oxford September 2005 Sean Grullon6 Non contained EHE cascades: Preliminary vertex resolution

7. Oxford Workshop September 21 st - 24 th, 2005 Oxford September 2005 Sean Grullon7 Current EHE cascade reconstruction plans Implement Photonics (Johan Lundberg’s Photorec functions) as the PDF in the reconstruction Look into cascade direction reconstruction Coordinate with Paolo Desiati for EHE event production.

8. Oxford Workshop September 21 st - 24 th, 2005 Oxford September 2005 Sean Grullon8 Future Directions for EHE reconstruction Get reconstruction tables with a much larger active volume Look into reconstructing EHE tracks…. …. Then look at IceCube data and do EHE physics!
