Das Lichtpulsersystem des elektromagnetischen CsI(Tl)-Kalorimeters des Babar-Detektors
A light pulser system for the Babar CsI(Tl) calorimeter, capable of monitoring the light yield of the 6580 crystals and of checking the function and linearity of the readout electronics, was developed in a collaboration with groups from Bochum and Edinburgh. The light pulser system is based on the …

Die Kalibration des elektromagnetischen CsI(Tl)-Kalorimeters des BABAR-Detektors mit Ereignissen der Bhabha-Streuung
Für das CsI(Tl)-Kalorimeter des Babar-Detektors wurde ein Verfahren zur Kalibration entwickelt und implementiert. Es ist in der Lage, für alle 6580 Kristalle absolute Kalibrationskonstanten zu bestimmen und die zeitliche Änderung der Kristalleigenschaften zu monitorieren. Der Algorithmus basiert …
