A novel Monolithic Active Pixel Sensor (MAPS) for charged particle tracking is presented. The partially depleted thin epitaxial layer of a low-resistivity silicon wafer is used as a sensitive detector volume from which the charge liberated by ionising particles is collected by diffusion. The sensor is a photodiode within a special structure allowing the(More)
This paper presents the design and characteristics of a front-end readout application-specific integrated circuit (ASIC) dedicated to a multichannel-plate photodetector coupled to LYSO scintillating crystals. In our configuration, the crystals are oriented in the axial direction readout on both sides by individual photodetector channels allowing the spatial(More)
I review progress on investigations concerning top quark physics and QCD at a future linear e+e collider that has been achieved since the presentation of the TESLA technical design report [1] in spring 2001. I concentrate on studies that have been presented during the workshop series of the Extended Joint ECFA/DESY Study on Physics and Detectors for a(More)
Swift, high resolution CMOS pixel sensors are being developed for the CBM Micro Vertex Detector (MVD), allowing for high density particle tracking. Designed at IPHC, the sensors are manufactured by the CMOS industry and can be thinned down to ≤ 50 μm. To accommodate the data rate, the signals delivered by the sensors are discriminated before being filtered(More)
The APVD_DC realised in the DMILL technology is a radiation-hard integrated circuit for front-end readout electronics of the silicon tracker of CMS. DC-coupled silicon microstrip detectors have significant economical advantages compared to AC-coupled devices mainly due to their less complex fabrication process and better yield. The APVD_DC allows the use of(More)
CMOS Monolithic Active Pixel Sensors (MAPS) are proposed as a technology for various vertex detectors in nuclear and particle physics. We discuss the mechanisms of ionizing radiation damage on MAPS hosting the the dead time free, so-called self bias pixel. Moreover, we discuss radiation hardened sensor designs which allow operating detectors after exposing(More)
Diamond is a nearly ideal material for detecting ionizing radiation. Its outstanding radiation hardness, fast charge collection and low leakage current allow a diamond detector to be used in high radiation, high temperature and in aggressive chemical media. We have constructed charged particle detectors using high quality CVD diamond. Characterization of(More)
