1. Root dictionary ROOT interactive or scripts (+RALICE)
Principle
Minimal interface Easy to use and understand
Uniform access Easy to switch between different
photon simulations
Usability
Shared library Compiled C++ programs
Fortran interface AMASIM (also works for C)
Root dictionary ROOT interactive or scripts (+RALICE)
Implementations
Local photonics working fine
TCP/IP photonics tested but not finished
Neural Net photonics planned
PTD problems compiling, need help

2. Required functions for implementations
Internal data
Optical Modules x,y,z,orientation(?)
Tracks type, E, x, y, z, f, j, length
Mean Amplitudes om, track,
Value in number of photo electrons
Hits om, track
Time delay and probability
Required functions for implementations
MakeMeanAmplitudes
Called when accessing a mean amplitude if tracks
or OMs have changed
MakeTimeDelays & MakeHitProbabilities
Called when accessing hit time delay or probability
when hits, tracks or OMs has changed

3. Usage PutOM Add a detector PutTrack Add a particle track
GetMeanAmplitude Get mean amplitude in detector from
track. Has to be corrected for area and
efficiency.
PutHit Add a hit in a detector from a track
GetHitTimeDelay Return hit time delay in ns, usually
relative to Cerenkov arrival time
(needs a random number)
GetHitProbability Return hit probability
(needs a time delay)

4. Stephan's Cowboy Test with PSInterface

5. Simple time delay test

6. Outlook Check the web page
More implementations TCP/IP (Instead of scatserver)
NN photonics
PTD?
Use the interface IceTray – Integrated by John P
RALICE - Integrated by Adam B
AMASIM – Not yet
Speed? Use smarter data representation
Reduce iterations
