Regarding ELOSS, the Tech Note (HDice_TN22) that I put together for Eugene can be downloaded from:<BR>

The Appendix at the end gives examples of explicit energy loss evaluations for pions and protons (a) near the low end of their acceptance (25 MeV for pions and 65 MeV for protons) and (b) at 1 GeV (~ minimizing ionizing for both). These were calculated for lab angles of 90 degrees where the material thicknesses are their least. The calculations assume events originate at the center of the target. As an extreme case, the Eloss from events coming from the outer edge of the HD nearest the detector would be down by the entries in the first two rows of the tables. There is no way a pion can loose less than 4.6 MeV by the time it exits the IBC and gets to the Start Counter.<BR>
