Clipp<strong>in</strong>g is an effective way <strong>of</strong> reduc<strong>in</strong>g OC effects at trigger<br />
(orig<strong>in</strong>al idea E. Lorentz)<br />
Σ<br />
Concept proven <strong>in</strong> MAGIC <strong>and</strong> also applied <strong>in</strong> FACT<br />
(see next talk)<br />
For the US SCT we do not plan a clipp<strong>in</strong>g stage <strong>in</strong> the trigger<br />
Because<br />
several <strong>SiPMs</strong> <strong>with</strong> OC elim<strong>in</strong>at<strong>in</strong>g trenches become available<br />
