Mon­i­tor­ing the muon beam prop­er­ties in the final stage of the Neu­tri­no Fac­to­ry (the Decay Ring) is im­por­tant for the un­der­stand­ing of the beam it­self and a cru­cial piece of in­for­ma­tion for the down­stream physics de­tec­tors. The main top­ics to be as­sessed are: knowl­edge of the muon beam en­er­gy, di­ver­gence of the muon beam and muon beam cur­rent. In the frame­work of the In­ter­na­tion­al De­sign Study for the Neu­tri­no Fac­to­ry (IDS-NF) a Race Track model Decay Ring based on G4beam­line has been pro­duced to un­der­stand how elec­trons from muon de­cays can be used to infer the en­er­gy prop­er­ties of the beam via the spin de­po­lar­i­sa­tion tech­nique. The use of other codes, like Zgoubi, to gen­er­ate a re­al­is­tic beam in­clud­ing ef­fects like spin po­lar­i­sa­tion, are con­sid­ered. A gen­er­al dis­cus­sion on the re­main­ing top­ics is pre­sent­ed.
