Discussion on integrating `neugen` into `gminos`

Objective

There seems to be some confusion/concern about what is necessary for integrating the interaction event generator into gminos in order to generate events consistent with the geometry described to GEANT. Key issues include:

Specifying the beam flux and its position and direction relative to the detector.
Performing the oscillation.
Generating events with the correct energy spectrum, off the right target nucleons.
Generating the correct vertex placement in the detector.

The charge of this group is to resolve the issues and produce working code in the very short time frame.

The "committee"

As is typical in a collaboration when it is unclear how to proceed, we did the natural thing: formed a committee. The current membership list (in no particular order) is:

Robert Hatcher - nominal chair since I volunteered to record the list
Adam Para
Alan Wehmann
Maury Goodman
Jeff Nelson
Rob Edgecock
Hugh Gallagher
Jim Hylen
Lynn Miller

If you'd like to be added/removed please mail me at: hatcher@astro.indiana.edu It'd like, as best I'm able, to make this discussion available to all interested parties, so if people don't mind I'll probably be taking any e-mail exchanges to the discussion below.

Discussion

RWH's initial (1196.03.08) thoughts on how this should proceed.

As one can see this approach attempts to isolate, as much as possible, the necessary components. On the one hand there are the parts that know something about "neutrino physics" (cross sections, fragmentation), and on the other hand there is the part that knows about the geometry.

I (RWH) see in writing this, that some of our earlier discussion on incorporating the parts together we, well, ah, neglected to mention the need for a package to perform the oscillations. Presumably this is all in hand and we simply need to package it in a form where it can act as an intermediate function which takes the neutrino returned by the flux package and transforms it into a new neutrino ready to be interacted. Oooh, is the length of either detector enough that we need worry about the difference in "L" from the front to the back?

neu.ddl - (current) data format

This shouldn't be taken as "fixed in stone" -- rather it is a point to work from. If people seem improvements such as things to add, remove or restructure, they should not hesitate to make suggestions.

Getting specific ...

initial call to arms

my intial message sent to FNAL mailing list MINOS_ALL. Followup messages should go to MINOS_SIM@FNAL.GOV with a suggested Subject: line of neugen-gminos integration. Please note that I can not sign you up for either list -- I suggest you contact Maury Goodman (mcg@hep.anl.gov)
