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)

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)
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)
A new CMOS low-power mixed A/D ASIC for radiation detector readout front ends is presented *. First, we recall the principle of radiation detection system before describing the whole architecture of the circuit. The discussion is then focused on the low-power issue. By means of an innovative 128:1 analog multiplexer, we show how we drastically reduced the(More)
Diamond radiation sensors produced by Chemical Vapour Deposition are studied for the application as tracking detectors in high luminosity experiments. Sensors with a charge collection distance up to 250 µm have been manufactured. Their radiation hardness has been studied with pions, protons and neutrons up to fluences of 1.9 × 10 15 πcm −2 , 5 × 10 15 pcm(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)
