Further measurements of turbulence in the working section are given with 2 and 3 screens in the bulge.nThe extended region of high intensity turbulence near the walls of the working section, which was observed with 9 screens in the bulge, disappeared when the number of screens was reduced from -9 to 2 or 3. The longitudinal component of turbulence is approximately independent of the number of screens;the lateral component does not change, if the number of screens is reduced from 9 to 3, but increases by a factor 2.5 to 3, if the number of screens is further reduced from 3 to 2.nIn order to explain the origin of the turbulence in the working section, further turbulence measurements have been made at the end of the second diffuser, before the rapid expansion and in the bulge.
