Colleagues, To clear up some questions regarding the attenuation length model in the lead glass that was derived by Radphi, I have posted some plots and a brief note on the wiki. Please find it at the address below. The short answer is that there is no evidence I can find of a number like 160cm in any of the Radphi records, but that is a matter of dusty archives at MK and I can sort out. Meanwhile, the definitive treatment is described in my note. http://www.jlab.org/Hall-D/software/wiki/index.php/Attenuation_Results_from_Radphi Richard Jones Kornicer, Mihajlo wrote: > > Hi all, > > originally it was 100 cm in the simulation, but I remember number like > 166cm from Radphi so I chose 160.
