We wish to measure the EMI efficiency at hadron momenta higher than the 3 GeV used at the Beavatron. We propose to use the 30 M3 bubble chamber as the momenum and spatial analyzer of charged hadrons both of the incident beam and those final state hadrons of interactions. that occur within the chamber. We would use the EMI modules as mounted on the bubble chamber vacuum tank (see Fig. 1) to measure the efficiency of the EMI absorbers (coils and zinc) over a wide range of momenta. A hadron signature would be either the lack of a proportional chamber (PC) encoding within the ''96 % muon-circle'' or a multiple PC encoding. We shall attempt to identify π-µ decays in the chamber to use as a source of muons.
