______________________________ Scope of the 1997 detector orders _____________________________________ A discussion was held to try and understand how many detectors would be needed and could be afforded by ATLAS in 1997. The requirements are - - to have sufficient detectors to build modules - >120 barrel detectors - >120 (=3x40) forward detectors - to get detectors from as many potential suppliers as possible (3?) - to irradiate >10detectors of each batch An example of a specific scenario : Company A - 2 x 50 barrel detectors - 2 x 50 forward detectors Company B - 1 x 50 barrel detectors Company C - 1 x 50 forward (inner ring) detectors
