84 Chapter 8 Implementation <strong>of</strong> Highly Segmented Strip Readout<br />
the production <strong>of</strong> the APV25 frontend modules and the other electronic components is expected to be<br />
available in early 2011 the commissioning <strong>of</strong> the triple GEM prototype 2.0 with APV based readout<br />
can be started soon.<br />
