By the beginning of 1990-ies, parallel architectures started to apply in microprocessor systems. At that time, the transputer architecture was considered to be the most prospective one, i.e., an architecture of specialized microprocessors to be used in parallel computations with the capability to create a computational environment with a multitude of processors. At the Institute of Nuclear Physics...
This paper presents preparing high voltage for Geiger counter along with data acquisition and monitoring technique by LabVIEW. A high voltage generation circuit is designed for the GM counter and the recorded data is stored, analyzed and monitored in a personal computer with the help of National Instruments Data Acquisition card (DAQ card). The interface between hardware and computer is done by the...
We present an FPGA-based online data reduction system for the pixel detector of the future Belle II experiment. At the SuperKEKB design luminosity of 8 × 1035 cm−2 s−1 and a trigger rate of 30 kHz, the occupancy of the pixel detector is conservatively estimated at 3 %. With its almost 8 million channels, this corresponds to a data output rate of more than 20 GB/s after zero suppression, dominated...
A processor-based Data Acquisition System (DAQ) for an array of Kinetic Inductance Detectors (KIDs) is described. KIDs are superconductive bolometers, in which any incident radiation could change the inductance of the detector. An array of N KIDs is composed of N detectors, each one resonating on its own frequency. A feed-line passes close to each KID and delivers a unique Stimulus signal containing...
The Belle II experiment is an e+e− collider for the search physics in the decays of B mesons, and it will start the operation in near future. The trigger rate is expected as 30 kHz and the raw data rate will exceed 30 GB/s. It is unable to record the data on the storage system, thus the online reduction is indispensable. We have developed a three-level event building system using inexpensive box switches...
The NA62 experiment at CERN will test the Standard Model (SM) of Particle Physics by measuring the Branching Ratio (BR) of the ultra-rare decay of a charged Kaon into a charged pion and two neutrinos (K+→π+νν). The main goal is to collect 100 such events in two years of data-taking, using high-energy in-flight Kaon decays from a 750 MHz hadron beam produced by 400 GeV/c SPS protons impinging on a...
Single photon avalanche diode (SPAD) arrays have proven themselves as serious candidates for time of flight positron emission tomography (PET). Discreet readout schemes mitigate the low-noise requirements of analog schemes and offer very fine control on threshold levels and timing pickup strategies. A high optical fill factor is paramount to timing performance in such detectors, and therefore space...
This paper describes technical aspects and details of the trigger system of NA61/SHINE experiment. The SPS Heavy Ion and Neutrino Experiment (SHINE) is a large acceptance hadron spectrometer designed for comprehensive studies of hadron production in hadron-proton, hadron-nucleus and nucleus-nucleus collisions at the CERN Super Proton Synchrotron. The NA61/SHINE physics programme requires measurements...
The T2K (Tokai-to-Kamioka) experiment is a long baseline neutrino experiment to observe the oscillation from mu neutrinos to electron neutrinos. Up to 2013, we achieved stable operation with 230 kW of the beam power and the number of protons per bunch is 1.2 × 1014 that is the highest intensity in the world. This manuscript describes about the data acquisition system for monitoring the high-intensity...
The LHCb data acquisition after 2019 will need to perform event-building at an aggregated band-width of 32 Tbit/s. Apart from the technological challenges described in various papers also at this conference, the key challenge is to come up with an architecture which minimises the cost, while providing a system which can be maintained by a small team for a long time and which scales well. In this paper...
The Data Acquisition (DAQ) system of LHCb is a complex, real-time system connecting more than 300 readout boards with more than 1500 servers by means of highperformance network 68 switches. The total data rate through this network is more than 60 GB/s. The DAQ network has a FAT-tree topology, composed of an aggregation and a distribution layer, where traffic flows unidirectionally to the server farm...
The Belle II experiment will start physics data taking in 2016 at the SuperKEKB factory to search for new physics beyond the Standard Model from flavor physics channels. A network distributed data acquisition (DAQ) system was developed for huge data size from the Belle II detector. In order to manage the distributed systems, software control and monitoring systems for the DAQ subsystems were newly...
An improved scheme to implement integral nonlinearity (INL) correction of time measurement for BES III endcap TOF (ETOF) upgrade system is presented in this paper. Methods for INL correction in HPTDC (high performance time to digital convertor) adopted in BES III TOF system are proved to be limited in upgrading MRPC system, because sharply increased electronic channels corresponding to detector read-out...
Since a few years Coherent Synchrotron Radiation (CSR) generated by short electron bunches is provided at the ANKA synchrotron light source. To study the THz emission characteristics over multiple revolutions superconducting YBa2Cu3O7-δ (YBCO) thin-film detectors can be used. The intrinsic response time of YBCO thin films is in the order of a few picoseconds only. For fast and continuous sampling...
Micro-Channel Plate (MCP) with higher quantum efficiency in Extreme Ultraviolet (EUV) region is widely applied in nuclear physics and space environment detection. We will describe a real-time data acquisition (DAQ) system for a two-dimensional MCP Detector, which is readout by a wedge-and-Strip Anode (WSA). We employ the filter and shaping technique. Finally, the resolution mask before the MCP stack...
In the framework of the ITER Control Breakdown Structure (CBS), Plant System Instrumentation & Control (I&C) defines the hardware and software required to control one or more plant systems [1]. For diagnostics, most of the complex Plant System I&C are to be delivered by ITER Domestic Agencies (DAs). As an example for the DAs, ITER Organization (IO) has developed several use cases for diagnostics...
The P̅ANDA detector at the future FAIR facility in Darmstadt, Germany will operate with a very high anti-proton interaction rate of up to 2 × 107/s in a free streaming mode without hardware triggers. Several hundreds of GB/s of data have to be read out. Sophisticated event filtering mechanisms based on tracking, calorimetry and particle identification are required in order to reject background events...
The MINOS (MagIc Numbers Off Stability) collaboration has developed a compact vertex tracker for in-beam gamma spectroscopy of very exotic nuclei. It comprises a cylindrical time projection chamber with a Micromegas amplification plane, a cylindrical tracker based on a curved Micromegas, and two off-the-shelf silicon detectors. In total, MINOS comprises ∼5000 channels. Besides performance goals, the...
The data acquisition and control system for user experiments at the X-ray Free Electron Laser facility, SACLA, has been in stable operation since March 2012. The system handles up to 5 Gbps throughput of X-ray imaging data that are produced by a mega-pixel two-dimensional detector, in synchronization with the 60 Hz of the beam repetition cycle. In the autumn of 2014, a new beamline, now under construction,...
