1. Photonics Workshop Summary (IceCube style) Taking steps to address baseline change - Adopted forward-looking approach - Deliverables and milestones defined - Need to front-load work schedule - Earned value peak in Y2004M03 - Low on FTEs - SOWs (verbal)

2. Photonics Workshop Agenda Status reports –Stephan: AMASIM interface, testing –Thomas: PSI – Photon Simulation Interface –Peter for Daan: NN table parametrization –John P.: Hit constructor Discussion & Planning –Assignments: who’s doing what, why not –Action items: what to do, homework –Schedule: do it now

3. AMASIM interface testing (Stephan H.) New photonics tables (infinite muons) Photonics shower tables Look at mean photon amplitudes as function of - distance - impact parameter - OM orientation as defined in figure ►

4. Photonics mimicking PTD Message: AMASIM interface works; Shower tables debugged PTD photonics impact parameterdistance

5. PTD/photonics ratios With PTD settings (educated guess)With favored photonics settings Sensitive to efficiency settings (glass, gel, QE, etc.) Message: photonics = PTD if efficiencies same 0 100 200 -100 -200 0 100 200 -100 -200

6. Photon table interface (Thomas B.)

7. Action Items Debug muon tables- Stephan Parameter impact matrix- Stephan Update AMASIM- Stephan Photonics web portal- Kurt, Paolo ( UW page) Table inspection tools- Thomas Parameter selection- Paolo Table production- Paolo Parameterization –NN fits: include in PSI (Thomas), Peter/Thomas/Daan talk –Memory mapping- Adam investigates –Angular binning- John Code maintenance, coordination (I3)- Jenni Testing- ???
