A crucial detector of the NA62 experiment is the beam spectrometer named Gigatracker. It consists of three stations of hybrid silicon pixels sensors with 150 ps (rms) of time resolution and 100 μm (rms) of space resolution. In addition the system operates under a high radiation environment and a high density of particles (up to 1.5 MHz/mm in the centre and 0.8 1 GHz in total). To meet these req...

We describe the three-dimensional holographic optical disc system for application as read-only memory. Several systems design issues are discussed including imaging optics, storage density, readout rate, and the alignment servo system. We demonstrate 40 bits=lm surface density and pixel-matched holographic data readout from a 12 cm disc spinning at 600 RPM.

High-density memristor-crossbar architecture is a very promising technology for future computing systems. The simplicity of the gateless-crossbar structure is both its principal advantage and the source of undesired sneak-paths of current. This parasitic current could consume an enormous amount of energy and ruin the readout process. We introduce new adaptive-threshold readout techniques that u...

This paper evaluates the potential for the real-time utilization of high frame rate image sequences using a fully parallel readout system. Multiple readout architectures for high frame rate imaging are compared. The application domain for a fully parallel readout system is identified, and the design for a fully parallel, monolithically integrated smart CMOS focal plane array is presented. This ...

A new readout imaging system with enhanced dynamic range (DR) and low power consumption is presented. The DR is enhanced by using feedback to control the integration time of the sensor. The feedback is implemented within an in-pixel-level ADC. The power consumption is reduced by switching the bias circuit off when it is not needed for the system, this readout circuit is used for a hybrid sensor...

We present test results and characterization of a data compression system for the readout of the NA62 liquid krypton calorimeter trigger processor. The Level-0 electromagnetic calorimeter trigger processor of the NA62 experiment at CERN receives digitized data from the calorimeter main readout board. These data are stored on an on-board DDR2 RAM memory and read out upon reception of a Level-0 a...

The Transition Radiation Tracker, made of 370000 cylindrical straws, is a combined tracking and electron identification detector, which is part of the ATLAS Inner Detector at the CERN LHC. The TRT on-detector electronics is made of 2 types of custom asics, handling the analogue signals from the straws, providing a ternary encoded output (ASDBLR), binning the incoming tracking discriminator sign...
