Radiation Hardness R&D at Liverpool:

The improvements in radiation hardness that result from using p-side read-out have resulted in a number of studies which have been presented at conference and published in the literature. Recent studies for LHC-b are proving that this technology copuled with oxygenation yeilds detectors sufficiently robust to withstand dose up to 10^15 p/cm^2. Liverpool concentrates on studies in terms of the most important operational properties, such as charge collection and noise with LHC speed electronics for full size strip detectors to final geometries. This emphasis has led to differences with the optimisations proposed in some other places.

A few very recent papers are attached below.

GLAST Detector R&D:

In 2001 Micron delivered 50 full sized detectors 9*9cm to Liverpool designs to the GLAST collaboration which are fully compliant with the GLAST specifications.

2 earlier prototype detectors within GLAST specifications were delivered to the UK groups and evaluated.

IV characteristics are presented for detector 1815-10 with the corresponding test structure diode depletion voltage measured to be 100V .

IV characteristics are also presented for detector 1815-14 which has a corresponding test structure diode depletion voltage of around 90V .

Interstrip capacitances as a function of voltage have been measured to be 7.6 +/- 0.6 pF for nearest plus next to nearest neighbours both with and without the bypass strip and 6.0 +/- 0.4 pF for just the nearest neighbours with and without the bypass strip.

The strip backplane capaictance above depletion is found to be 5.0 +/- 0.1 pF as expected from simple geometry, giving the total strip capacitive load seeen by the electronics as 12.6 +/- 0.6 pF per detector.

The resistor values measured across 1815-25 have mean value 42.4 MOhms with a spread of 2.3 MOhms.

We have checked the metal lines and find 40.4 +/- 1.3 Ohms for the aluminium strips with 86.9 +/- 1.6 Ohms on the bypass strips.

The shorted capacitor strips on all devices have been checked with 50V across the capacitors. The number of bad strips are 0 for 1815-10, 4 for 1815-14 and 2 for 1815-25.
