Sumario: | The ATLAS pixel detector is based on a set of radiation-hard electronics chips able to resist a dose of 500 kGy. The implementation of these chips in the DMILL technology did not give the expected results. Re-design of the radiation-hard chips in Deep SubMicron technology is ongoing, but has implied a one and a half year delay in an already tight schedule. Major layout changes have therefore been necessary to allow installation of the ATLAS pixel detector at LHC start-up. This paper illustrates the status of the ATLAS pixel project, die motivations for the new layout, the way this should be implemented and the prototype fabrication and testing. (4 refs). |
