Modern scientific instruments, such as detectors at synchrotron light sources, can generate data at 10s of GB/sec. Current experimental protocols typically process and validate data only after an experiment has completed, which can lead to undetected errors and prevents online steering. Real-time data analysis can enable both detection of, and recovery from, errors, and optimization of data acquisition...
There are several evidence of magnetic field alterations that have been registered instants before seismic activity, in different parts of the world. Under the hypothesis that there is a relation between both phenomena, a multiple disciplinary project is being developed for verifying this statement. In this paper, a prototype for a data acquisition system is presented for obtaining valuable information...
Directional dark matter detection seeks to reconstruct the angular distribution of dark matter particles traveling through the laboratory. A directional detector with high spatial resolution has the potential to increase the sensitivity per unit volume by over two orders of magnitude, but requires the development of a high-channel-count, high-speed readout system. This paper describes an FPGA-based...
Fully depleted thick CCDs have been designed for infrared astronomy, but their low read-out noise of the order of ã 2 e− and their considerable mass of ã 5.2g, allows novel uses for them in low energy threshold particle detection applications, such as the CONNIE and DAMIC experiments. For both experiments, a reduction of the CCD read-out noise is will produce an increase in the detection efficiency...
Solid-state lighting is a field that has developed rapidly over the recent years. Visible Light Emitting Diode (LED) has achieved higher luminous efficacy than that of incandescent light, subsequently incorporated into many lighting systems in household or in workplaces. Energy saving can be achieved by utilizing adaptive lighting systems which can adapt to ambient lighting. We discuss the ability...
We present performance characterization of a bio-potential recording system with an asynchronous readout architecture. The signal processing chain consists of a low-noise bio-potential amplifier, spike detection circuitry, and an address event representation (AER) communication protocol. The system was fabricated in a 0.5 pm CMOS technology. Each stage of the recording system was tested individually,...
Data acquisition systems for large-scale high-energy physics experiments have to handle hundreds of gigabytes per second of data, and are typically implemented as specialized data centers that connect a very large number of front-end electronics devices to an event detection and storage system. The design of such systems is often based on many assumptions, small-scale experiments and a substantial...
This paper presents the proposal of a new front-end readout electronics (RO) architecture for the ALICE Charged-particle Veto detector (CPV) located in PHOton Spectrometer (PHOS), and for the High Momentum particle IDentification detector (HMPID). With the upgrades in hardware typology and proposed new readout scheme in FPGA design, the RO system shall achieve at least five times the speed of the...
Radiation due to high energy Cosmic Ray particles is known to cause anomalies in the electronic devices. As the devices get smaller the effects could lead to drastic results. A near space experiment was designed to study the variation of the cosmic rays with altitude. This paper presents the details of the experiment focusing on the embedded system designed specifically for the experiment. The data...
The need for simultaneous neutron and gamma detection continues to motivate the development of dual mode radiation detectors. One promising candidate is the elpasolite inorganic scintillator Cs2LiYCl6:Ce (CLYC). Previous studies, with other dual neutron–gamma detectors (EJ-299/EJ-309), have shown that the choice of digital data acquisition (DAQ) system can significantly affect pulse shape discrimination...
The data acquisition system for a highly granular Analogue Hadron Calorimeter (AHCAL) for the future International Linear Collider (ILC) will be presented. The developed DAQ chain has several stages of aggregation and scales up to 4 million channels in the main barrel foreseen for the AHCAL design. The front-end electronics will be embedded in the detector layers in between absorber plates without...
The China Seismo Electromagnetic Satellite (CSES) aims to contribute to the monitoring of earthquakes from space. This space mission will study electromagnetic phenomena and their correlation with the geophysical activity. The satellite will be launched in 2017 and will host several instruments onboard: two magnetometers, an electrical field detector, a plasma analyzer, a Langmiur probe and an High...
Many applications require the generation of gamma spectra at event rates in excess of 106 s−1 as well as very good energy resolution, e.g., safeguards, emergency response, and nondestructive assay. Good energy resolution is especially important when lower activity isotopes are sought among a large background (or foreground) that would otherwise dominate the spectrum, such as the minor actinides present...
The Compressed Baryonic Matter (CBM) experiment is a part of the Facility for Antiproton and Ion Research (FAIR) at Darmstadt, Germany. The challenge in CBM experiment is to measure the particles generated in nuclear collisions with unprecedented precision and statistics. To capture the data from each collision a highly time synchronized fault tolerant self-triggered electronics is required for Data...
Gamma-imaging system is of great interest to monitor the contamination of radioactive substances in a wide range of areas at nuclear power plants. The purpose of this study was to develop a compact gamma camera capable of detecting and imaging the radioactive sources present in contaminated area. The prototype of compact gamma camera with 73 × 99 mm2 FOV was composed of pinhole collimator, SiPM based...
SIRIUS is a state-of-the-art detector system for nuclear decay spectroscopy that will be mounted at the focal plane of S3 (Super Separator Spectrometer), which is part of the new SPIRAL2 facility at GANIL, Caen in France. Such a system requires high performance as it is dedicated to the study of very exotic nuclei. It is the result of collaboration between GANIL CSNSM, IRFU, and IPHC It is composed...
We introduce a compact preclinical PET detector that combines the output from 64 SiPM channels, forming an 8×8 matrix of pixels capable of efficiently encoding event position, with good energy and time resolution, as well as depth of interaction information. The scintillator matrices used to characterize the detector are a 16×16 matrix comprised of 1.3×1.3×12mm3 LYSO crystals, and a 1.3×1.3×15mm3...
With increasingly sophisticated experiment, online Data Quality Monitoring (DQM) is of a significant importance for the detector and operation efficiency. Most experiments use their own Event Data Model (EDM) for data taking and built a dedicated monitoring system on top of it. This leads to a strong dependency to the data format and storage, making the reusability of the system for another experiment...
An independent monitoring system aiming for the detection of deviations from the prescribed treatment in hadrontherapy is presented. The system is based on prompt gamma-ray detection via scintillation detectors and the use of time-of-flight information. Test measurements at cyclotrons show the influence of degraders used in passive beam delivery systems. A dedicated data acquisition card has been...
