Abstract
The new barrel Instrumented Flux Return (IFR) of BABAR detector will be reported here. Limited Stramer Tubes (LSTs) have been chosen to replace the existing RPCs as active elements of the barrel IFR. The layout of the new detector will be discussed: in particular, a cell bigger than the standard one has been used to improve efficiency and reliability. The extruded profile is coated with a resistive layer of graphite having a typical surface resistivity between 0.2 and 0.4 MOhm/square. The tubes are assembled in modules and installed in 12 active layers of each sextant of the IFR detector. R&D studies which have been done to choose the final design will be discussed, as well as the Quality Control procedure adopted during the tube production to assure high performances of the detector.
