1. Anita-Sim David Seckel, ANITA Collab. Mtg. Nov. 24-25, /2002 Notes on building a full ANITA simulation.

2. Anita-Sim David Seckel, ANITA Collab. Mtg. Nov. 24-25, /2002 Outline Event Generator Shower parameterization Pulse Propagation through ice Ice/air interface Propagation through air Antennas Instrument model 1: trigger side Instrument model 2: waveform side

3. Anita-Sim David Seckel, ANITA Collab. Mtg. Nov. 24-25, /2002 Event Generator Earth model Need local topography, geology, air Neutrino cross-sections standard model PQCD (+/- 25%) –NC/CC different levels of agreement. Non standard model cross-sections Tau propagation Other particles…Monopoles…

4. Anita-Sim David Seckel, ANITA Collab. Mtg. Nov. 24-25, /2002 Shower parameterization simple: N max, curvature d 2 N/dx 2 list of sub-showers … tbd

5. Anita-Sim David Seckel, ANITA Collab. Mtg. Nov. 24-25, /2002 Pulse creation Real pulse includes all the propagation issues… Do a spectral analysis, reconstruct at the antenna
