Abstract
For the two big bubble chambers BEBC and Gargamelle (GGM), detectors for external muon identification had been requested. Choice was given to multiwire proportional chambers behind additional iron absorbers. 71 chamber modules (each 1 x 3 m2) with two independent anode wire planes and one cathode strip plane have been built. To record the particle hits without deadtime during the spill length of 3 ms the development of a readout system quite different from standard systems was necessary. The chambers, the electronics and the performance of both systems will be described.
