1. 1 Recon tests, Sci Fi status and Sci Fi design iteration Malcolm Ellis MICE Software Phone Meeting Wednesday 28 th April 2004

2. 2 Reconstruction Tests Still not had time to implement anything yet (sorry!) Plan one test per component of the Sci- Fi reconstruction Tests will create instances of each object in pre-determined circumstances and check that all methods produce expected output.

3. 3 Classes to be tested SciFiDigits SciFiDoubletCluster SciFiSpacePoint SciFiKalTrack (SciFiTrack is being phased out) Timescale – depends on other priorities, hopefully by mid-June (I’m unavailable for any MICE work for all of May…)

4. 4 Sci Fi Reconstruction Status Light yield and fibre pitch updated for last collaboration meeting (not commited yet) Currently making SciFiKalTrack independent of SciFiTrack (so we can remove dependence on ROOT) In addition, new version of Kalman (commited to CVS) gives better dE/dx correction – currently preparing dE/dx model for this to be used in Sci Fi track fit. Aim to have this working and commited before I go offline on Friday…

5. 5 SciFi Design Iteration So far, have looked at the reconstructed classes as well as the modelling. ArgoUML does not allow me to add qualifiers such as const, nor to explicitly specifiy pointers, references or STL collections, so I will present a bare diagram on the next page, followed by the signatures written out in plain text for each class on subsequent pages. Where a class is derived from another class, I will not repeat the method description in the derived class. I have not explicitly listed copy constructors, etc – they will of course be added!

19. 19 Further detailed design Once I get back in June, we should discuss a number of things: 1. Progress in other areas of responsibility 2. Check detailed design of the tracking/particle ID work done at CERN 3. Discuss persistency options, make a decision and start work on it (I can make a presentation on the “iDST” option in June) Also in June, I’ll start to enter these prototypes as C++ code into the new CVS area.
