Dear collegues,
the new version of GMACRO (V7.21) is right and may be found in
rsgs02:/macrosoft/gmacro/v7.21/gmacro.car
The iron structure of MACRO, relevant for the neutrino interactions in
the detector, was introduced.
The new geometry is now a little different from those described in the
last message of Bob.
Here we show you the new geometry and the estimation of the MACRO mass.
One comment is necessary: The density of the absorber, which is the most
important contribution to the weight, was taken following some
indication of Mario Spinetti and is 2.55 g/cm**3.
This number and the quantity of absorber in the boxes are the most
important uncertainties in the mass estimation.
Best Regards Alessandro, Ernesto & Giovanni
