Ignore the "KEK November 2007" title - that's a legacy and is already changed :-)
As of now, there is no distinction in 16 separate zones. However, the gaps between the the zones are clearly visible in the Hit Profile, as the edge strips |

soeben haben wir den micron-DSSD (double metal layer) in den 2-teiligen rahmen geklebt und auf beiden seiten
temporäre kapton-stückerln aufgeklebt, über die bias appliziert werden kann. nach trocknung und bonden der
bias-verbindungen (montag, 5.5.2008) wird dieser für sensor-tests zur verfügung stehen. |
