Description
This contribution will report about the ATLAS Luminosity measurements
using a Scintillating Fibre Detector in a Roman Pot system. A description of
the Roman Pot system will be made together with a description of the
development, construction and operation of ALFA (Absolute Luminosity For
ATLAS) scintillating fibre detector prototypes. The ATLAS Roman Pots will be
located at 240 m from the ATLAS interaction point at LHC. The constraints
on the precise positioning of the detector will be illustrated as well as the
good results from two beam tests carried out at DESY (2005) and at CERN
(2006). The test beam data proved the good resolution and efficiency of the
fibre detectors making them suitable for the precision measurements
foreseen. The contribution will also discuss about the limited space available
for the electronics and the very compact system developed for the readout
of multi-anode photomultipliers.
