A multielectrode array system has been developed to study how the retina processes and encodes visual images. This can simultaneously record extracellular electrical activity from hundreds of retinal output neurons as a dynamic image is focused on input neurons. The signals detected be correlated with neural code used by eye send information about world brain. consists following components: 1) 32 /spl times/ 16 rectangular 512 planar microelectrodes sensitive area 1.7 mm/sup 2/; electrode...
A low-noise, mixed-signal, 128-channel CMOS integrated circuit containing the complete readout electronics for BABAR Silicon Vertex Tracker has been developed. The outstanding feature of present implementation is ability to perform simultaneously low-level signal acquisition, derandomizing data storage, sparsification and transmission on a single monolithic chip. signals from detector strips are amplified, shaped by CR-RC/sup 2/ filter with digitally selectable peaking time 100 ns, 200 300...
The Heavy Photon Search (HPS), an experiment to search for a hidden sector photon in fixed target electroproduction, is preparing installation at the Thomas Jefferson National Accelerator Facility (JLab) Fall of 2014. As first stage this project, HPS Test Run apparatus was constructed and operated 2012 demonstrate experiment's technical feasibility confirm that trigger rates occupancies are as expected. This paper describes readout electronics its performance. In setting, heavy can be...
In a successful engineering run, the Heavy Photon Search Collaboration demonstrates that its upcoming heavy photon search experiment will be able to probe so far unexplored parameter regions in for dark photons.
Charge collection properties of particle detectors made in HV-CMOS technology were investigated before and after irradiation with reactor neutrons. Two different sensor types designed processed 180 350 nm by AMS. Edge-TCT charge measurements electrons from 90Sr source employed. Diffusion generated carriers undepleted substrate contributes significantly to the irradiation, while drift contribution prevails as shown at shaping times. The depleted region a given bias voltage was found grow...
For the Phase-II Upgrade of ATLAS Detector [1], its Inner Detector, consisting silicon pixel, strip and transition radiation sub-detectors, will be replaced with an all new 100% tracker, composed a pixel tracker at inner radii outer radii. The future include 11,000 sensor modules in central region (barrel) 7,000 forward (end-caps), which are foreseen to constructed over period 3.5 years. construction each module consists series assembly quality control steps, were engineered identical for...
Optical links are used for the readout of 4088 silicon microstrip modules that make up SemiConductor Tracker ATLAS experiment at CERN Large Hadron Collider (LHC). The optical link requirements reviewed, with particular emphasis on very demanding environment LHC. on-detector components have to operate in high radiation levels 10 years, no maintenance, and there strict power consumption, material space. A novel concept packaging optoelectronics has been developed meet these requirements....

In paper we present and measurement results. basic analogue performance evaluated using SCT module equipped with chips. digital general purpose IC tester. measurements confirmed that all blocks are fully functional chips meet requirements SCT. Wafer screening performed customised wafer
We have designed and tested a 64 channel amplifier-comparator integrated circuit on the Maxim SHPi bipolar process. The low power design, 840 /spl mu/W/channel, is intended for use as frontend with high clock rate silicon strip detector systems. Peaking time at comparator input 20 ns, good double pulse resolution, noise near optimum technology used. used chip successfully in proton beam test KEK Japan 40 MHz data clock.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML"...
