Status Spring 2007<br />
detailed investigations:<br />
using ~ 40 x 1cm 2 sample detectors<br />
• material properties checked<br />
• radiation hardness proven<br />
• segmentation scheme optimized<br />
• lithography improved (15µm)<br />
• efficiency > 98%<br />
• fast preamps vacuum suited<br />
• good TOF resolution<br />
• 1 st prototype of APV readout<br />
next steps:<br />
intermediate size prototypes<br />
separate detector – electronics<br />
test of high resolution tracking<br />
