The use of a conventional streak camera for subnanosecond timeresolved fluorimetry is extended to the single-photon counting regime by utilizing intensified readout of the phosphor. The system achieves the usual k e y advantages of photon counting, namely single-photon sensitivity, large dynamic range and shot noise limited statistics, but also permits measurements of lower repetition rate and ...
We describe the control and performance of a new near-infrared camera based on a Rockwell PICNIC array detector for interferometry observations at the Infrared-Optical Telescope Array (IOTA). The camera control uses a complex programmable logic device that allows fast and stable clocking of the PICNIC array and on-the-fly reconfiguration of the readout method. We measured a read noise as low as...
In a magnetic amplifying magnetooptical system (MAMMOS) disk, the copying process of a magnetic domain from the recording layer into the readout layer is investigated by using a laser spot diameter of 0.66 m. Interference between neighboring bits occurs when the spatial resolution of the copy process is larger than half the domain size. It is observed that a reduction of the readout power from ...
We discuss the various electronic configurations one can use to readout resistive bolometers such as those based on Neutron Transmuted Doped Germanium thermometers (so called NTD Ge thermometers)[1] or NbSi thin film thermometers [2, 3]. The simple voltage amplifier configuration, is compared to readout configurations with feedback on the bolometer. Using the adiabatic thermal model of bolomete...
In this contribution we will report on the progress of the design of the readout and data acquisition system being developed for triple-GEM detectors which will be installed in the forward region (1.5 < |η |< 2.2) of the CMS muon spectrometer during the 2nd long shutdown of the LHC, expected in the period 2017–2018. The system will be designed to take full advantage of current generic developme...
The aims of the CALICE test beam program are presented. The proposed electronics readout system for the CALICE ECAL is described. It is a purposebuilt VME-based, unbuffered system. 1 The CALICE Collaboration The CALICE collaboration [1] is a group of 140 people from 24 institutes in Europe, US and Asia. The collaboration is planning a beam test program starting in 2004 to study both electromagn...
In the present work we intend to assess the readout feasibility of Avalanche Photodiode (APD) detectors via long signal lines for the development of a combined small-animal PET-MR prototype based on the ClearPEM technology. The detection performance of a LYSO-APD module was evaluated reading out the APD charge signals to the front-end ASIC via an 80 mm length flexible flat-cable (FFC). Experime...
GSI, Darmstadt, Germany Abstract: Hamamatsu Multi Anode Photomultipliers H8500-03 are currently foreseen as photodetector for the CBM-RICH. To operate the H8500-03 with the nXYter chip, which is a prototype of a future CBM data acquisition readout, the photomultiplier signals have to be strongly attenuated. An attenuator in form of a charge divider has been developed and tested. After laborator...
The silicon microstrip detector type with nþ readout fabricated on p bulk, nþ-on-p, is a candidate to be operational in radiation environments much severer than in LHC. We characterized nþ-on-p detectors which were irradiated up to 1:1 10 protons=cm 10 years ago. The noise level and charge collection were evaluated using the ATLAS SCT readout electronics system. Radiation-induced increase in th...
Abstract Waveform digitizers are key readout instruments in particle physics experiments. In this paper, we present a waveform digitizer for the PandaX dark matter It supports both external-trigger and triggerless readout, accommodating needs of low rate full-waveform channel-independent threshold acquisition, respectively. This is 8-channel VME board with sampling 500 MS/s 14-bit resolution ea...
