ABSTRACT: We report on a new approach in the design of CMOS monolithic active pixel sensor (MAPS). We realized a first MAPS prototype chip implementing at the pixel level the standard processing chain commonly used for capacitive detectors. The in-pixel signal processing channel includes a low noise charge preamplifier, a shaper, a discriminator and a latch. This readout approach, realized exploiting the triple well option available in the 0.13 mum process by STMicrolectronics, is compatible with already available architectures performing data sparsification at the pixel level. This feature will be implemented in future development of our device to improve the readout speed potential of these sensors with respect to existing MAPS. Using a charge preamplifier to perform charge to voltage conversion, we also extended the area of the sensing electrode to increase the signal collected by a single pixel. The first prototype chips have been successfully tested with very encouraging results. In this paper we summarize the performance of the front-end electronics and present the response of the sensor to ionizing radiation

ABSTRACT: We irradiated with photons from a60Co source a double-sided d.c.-coupled silicon strip detector and several test structures fabricated at CSEM. We measured the
leakage currents and the interstrip and backside capacitances. Up to a maximum dose of 1 Mrad, the current densities are always
below 350 nA/cm2, mostly due to thermally generated surface currents. The interstrip capacitances increase at most 17% with respect to not
irradiated detectors, while the backside capacitances do not change.

ABSTRACT: A description of the ALEPH Vertex Detector (VDET 91), including
the mechanical structure and the improved data acquisition system, is
given. The apparatus consists of two complete layers of silicon
detectors with double-sided readout which provide a full x, y, z
information of the impact points of charged particles. The authors show
results on signal-to-noise ratio for minimum ionizing particles and
efficiency in hit/track matching. Results on position, impact parameter,
and momentum resolution are also shown as measured using high momentum
muons. The first preliminary study on vertexing techniques and their
impact on physics analysis is discussed

The apparatus consists of two complete layers of silicon detectors with double-sided readout which provide full x,y,z information on the impact points of charge particles. The authors present results on signal-to-noise ratio for minimum ionizing particles and efficiency in hit/track matching. Results on position, impact parameter, and momentum resolution are also shown as measured using high-momentum muons. Preliminary results on single hit and impact parameter resolution show that the detectors and VLSI read-out electronics work as expected, and the performance compares well with previous test beam results and Monte Carlo simulations. Preliminary results on precision vertex reconstruction show a significant improvement in the data analysis which will be fully exploited in studying tau , b and c physics when all statistics are available.< >

ABSTRACT: A fastbus module, the Cosmic Logic Unit (CLU), has been designed
and built to form a muon trigger using the digital data coming from the
limited streamer tubes of the Warm Iron calorimeter (WIC) of the
Stanford Large Detector (SLD) at the Standard Linear Accelerator Center
(SLAC). The trigger configuration can be changed simply by downloading
new trigger tables to two levels of fast-access-time RAMs, without
interfering with the SLD data acquisition system. The module can handle
two different types of trigger configurations: one for muons produced in
the e <sup>+</sup> e <sup>-</sup> collisions and one for
cosmic muons, with the purpose of monitoring and calibrating the whole
apparatus on line

ABSTRACT: We describe our experience on design and fabrication, on high-resistivity silicon substrates, of microstrip detectors and integrated electronics, devoted to high-energy physics experiments and medical/industrial imaging applications. We report on the full program of our collaboration, with particular regards to the tuning of a new fabrication process, allowing for the production of good quality transistors, while keeping under control the basic detector parameters, such as leakage current. Experimental results on JFET and bipolar transistors are presented, and a microstrip detector with an integrated JFET in source–follower configuration is introduced.

ABSTRACT: We present a new approach to the design of monolithic active pixel sensors (MAPS) in CMOS technology. By exploiting the triple well option, available in modern deep-submicron processes, it was possible to implement at the pixel level a full analog signal processor and to increase the area of the sensing electrode. These two new features aim to address some limiting aspects of conventional MAPS, such as the read-out speed and the charge collection efficiency. We report on the characterization of the first prototype chip, in particular the calibration with soft X-rays and the response to β-rays, demonstrating the capability of the sensor in detecting ionizing radiation.

ABSTRACT: The Silicon Vertex Tracker (SVT) of the BABAR experiment at the PEP-II asymmetric B factory is a five layer double sided, AC coupled silicon microstrip detector. It represents the crucial element to precisely measure the decay position of B mesons. The SVT architecture is shown and its performances, like hit resolutions and efficiencies, are described. Radiation issues are discussed and the alignment procedure for the SVT is described. As an example for the physics performance the B lifetime measurement, including B vertex reconstruction, is shown.
