Experimental studies on the planar drift chamber of the ZEUS forward detector
Description
The planar drift chamber FTD2 of the ZEUS forward detector was tested with an e--beam of 2.0 GeV at the DESY synchrotron. Using the information of one cell a single wire spatial resolution of 105 μm was found for the homogeneous part of the drift field. The hit-finding efficiency was better than 99%. About 96% of the left-right ambiguities were resolved already at cell level. Using tracks crossing two cells of one layer the computed single wire spatial resolution is comparable to the resolution at cell level. Linking the information from the 3 layers was done by calculating a cartesian representation of three dimensional tracks. In a coordinate system which equalizes the x- and y-resolution the resolution of the x-and y-slopes were found to be about 2.7 mrad and spatial resolution of 89 μm were obtained. (orig.)

Im Rahmen der vorliegenden Arbeit wurde die zuerst fertiggestellte planare Driftkammer fuer den ZEUS-Vorwaertsdetektor FTD2 mit einem Elektronenstrahl getestet. Bei einer Strahlenergie von 2,0 GeV und festem Einschusswinkel von etwa 15deg zur Kammeroberflaeche wurden bei unterschiedlicher horizontaler Kammerposition knapp 110 000 Spuren aufgezeichnet. Die Auswertung dieser Daten erlaubte auf Zellniveau die Kalibration der Draehte einer Zelle hinsichtlich ihres Zeitoffsets t0 und Staggerings, wobei im Rahmen der Genauigkeit der verwendeten Orts-Driftzeit-Beziehung (ODB) das nominelle Staggering von 150 μm bestaetigt werden konnte.
