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

  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. 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. 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. 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!

  6. Reconstruction DetModel DetRep?

  19. Further detailed design • Once I get back in June, we should discuss a number of things: • Progress in other areas of responsibility • Check detailed design of the tracking/particle ID work done at CERN • 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.
