Rui Nunes ST/AA/AS - STTC 21 Feb 2000 What happened to the old equipment? Removal/renewal of all detection equipment –Adapt to new use of installations –Reduce maintenance costs Replace with less and better Remove obsolete/useless –Improve performance Reduce spurious alarms –To achieve this, we need Input from users (TIS, ST, Experim, etc)
