A DEPFET Pixel Vertex Detector for TESLA Proposal and Prototyping Report

چکیده
DEPFET pixels offer a unique possibility for a high resolution pixel vertex detector as the innermost component of the tracking system in the TESLA detector. DEPFET pixels excel in comparison to other pixel detectors in the simultaneous achievement of high spatial, energy and time resolution even at room temperature operation. In the DEPFET pixel scheme the signal charge is not shifted out but is stored in the pixel until readout. Multiple readout is possible. The detector itself can be made very thin and does consume very little power. In this note the concept to use the DEPFET technology for the TESLA vertex detector is discussed. Possible design options for a DEPFET based vertex detector are presented and the progress of the R&D program which is presently carried out to meet the requirements at TESLA is described. In particular the advancements in sensor optimization and in the development of a fast readout scheme are discussed.

Two barrel layers will be installed in a very confined space and hence...
متن کاملA Novel Pixel Vertex Detector for the Belle II Experiment at SuperKEKB
At the KEK laboratory in Tsukuba, Japan, the upgrade of KEKB to “SuperKEKB” has started. Due to the much higher backgrounds expected at SuperKEKB, a massive upgrade of the Belle detector (“Belle II”) is in progress as well. For the innermost layers, close to the beam pipe, strip sensors will not work anymore due to the large occupancies, and a pixel detector becomes mandatory for Belle II. We r...
