Irradiation period July '99

24 GeV/c CERN/PS proton beam. The cumulated fluence is 3 10¹⁴ cm^-2.

Preirradiation measurements:
I-V; Interstrip capacitance: oxygenated and control ; Strip vs backplane capacitance.
Measurements after irradiation:
I report also the very firsts results with microstrip detectors processed by MICRON on 4" <100> silicon substrate oxygenated for 110 hours at 1100 ^oC.

I-V's: comparison between oxygenated and control. C-V's: comparison between oxygenated and control.
Intrstrip capacitance: oxygenated and control
Charge collection efficiency: comparison between MICRON microstrip (6x6 cm²) control un-oxygenated and
oxygenated detectors with laser (1064 nm) and source (¹⁰⁶Ru) signals.
All the measurements after irradiation have been performed on detectors having completed the beneficial annealing phase.

Irradiation period November '99

24 GeV/c CERN/PS proton beam. The cumulated fluences are 3 10¹⁴ and 3 10¹⁴ cm^-2.

Full size barrel, wedge and miniature detectors were irradiated in this irradiation run, both in the ATLAS cool-box (under bias) and in the PS-shuttle.
Some of the miniature detectors were irradiated in the shuttle up to 4 10¹⁴ cm^-2.
The detectors were made with oxygenated and standard substrates.
Preirradiation measurements:
I-V's of standard and oxygenated Micron wedge detectors and of the corresponding miniature detectors.
C-V's of some standard and oxygenated Micron wedge detectors
Measurements after irradiation:
IV and CV of MICRON wedge detectors.
IV of miniature detectors irradiated to 3 10¹⁴ cm^-2 (cool-box, shuttle) and (IV) to 4 10¹⁴ cm^-2 (shuttle);
CV of miniature detectors irradiated in the shuttle: 3 10¹⁴ cm^-2 and 4 10¹⁴ cm^-2
CCE (with light spot from 1060 nm laser) of oxygenated and control miniature detectors irradiated to 3 10¹⁴ cm^-2.
