We present the results on MDT (monitored drift tubes) autocalibration
studies obtained from the analisys of the data collected in Summer 199
5 on the H8B Muon Test Beam. In particular we studied the possibility
of autocalibration of the MDT using four or three layers of tubes, and
we compared the calibration obtained using a precise external tracker
with the output of the autocalibration procedure. Results show the fe
asibility of autocalibration with four and three tubes and the good ac
curacy of the autocalibration procedure.
