and following Poster B session
An experiment to search the charged lepton flavor violation named COMET is prepared at the J-PARC research facility. The COMET experiment searches for the coherent neutrinoless conversion of a muon to an electron in muonic atoms.
The data acquisition system of the COMET detector is a network-based system that consists of two layers, the front-end network, and the back-end network. The...
Keda Torus eXperiment (KTX) is a reversed field pinch (RFP) device in the University of Science and Technology of China. Resistive wall modes (RWMs) and tearing modes (TMs) of RFP configuration limit the increase of discharge duration of the device.
The article introduces the experiment and results of active control of RWMs with m=1, |n|≤5 by controlling the external power supply and saddle...
In radionuclide metrology, ionization chambers have been used for activity and half-life determinations. The accurate measurement of the ionization current is required to improve the uncertainty levels of these determinations.
An accurate small direct currents measurement system is designed, including an amplifier circuit, an ADC, an FPGA control and readout circuit, and the user interface....
Event detection in fusion experiments is essential for plasma control during discharges and requires fast data acquisition and processing to meet real-time constraints, which demands the implementation of FPGA-based data acquisition and detection systems. The randomized power martingale RPM algorithm deals with the changing nature of a multidimensional dataset, detecting changes in the data...
The new Muon-Central-Trigger-Processor-Interface (MUCTPI) is part of the upgrade of the ATLAS Level-1 trigger system for the upcoming run of the Large Hadron Collider at CERN. The new MUCTPI has three high-end FPGAs and one SoC. The FPGAs receive and process muon candidate information arriving on 208 high-speed optical serial links. Processed trigger information and summary data are sent to...
Most of the neutron spectrometers planned in the China spallation neutron source (CSNS) are based on position-sensitive 3He tube detectors. To reduce the influence of air on neutron scattering experiments, the detector must be placed within a vacuum chamber for this kind of spectrometers. The readout electronics should also be placed within the vacuum chamber, so the number of feed-through...
This submission describes revised plans for Event Filter Tracking in the upgrade of the ATLAS Trigger and Data Acquisition System for the high pileup environment of the High-Luminosity Large Hadron Collider (HL-LHC). The new Event Filter Tracking system is a flexible, heterogeneous commercial system consisting of CPU cores and possibly accelerators (e.g., FPGAs or GPUs) to perform the...
The Front-End Link eXchange (FELIX) system is a new ATLAS DAQ component designed to meet the evolving needs of detector readout into the High-Luminosity LHC era. FELIX acts as the interface between the data acquisition; detector and trigger timing and systems; and new or updated trigger and detector front-end electronics. FELIX routes data between custom serial links from front-end electronics...
The iPET is a preclinical PET system based on the easyPET scanning method, an affordable PET technology capable of acquiring real-time high-quality in-vivo images with only two detector heads, at a reduced cost without compromising image quality. Full body mouse imaging is possible using a small number of detector elements, scanning billions of lines of response (LoRs) in few minutes, covering...
This paper presents the design of readout electronics for Muon Beam Monitor in COMET (Coherent Muon to Electron Transition) experiments. The Muon Beam Monitor in this experiment is a mesh structure consisting of a total of 256 Scintillating Fibers (SCSF-3HF) in two vertical directions, respectively. For the purpose of profiling the muon beam, electronics are required to measure the time-origin...
The Cooling Storage Ring of the Heavy Ion Research Facility in Lanzhou (HIRFL-CSR) is constructed to study nuclear physics, atomic physics, interdisciplinary science, and related applications. The External Target Facility (ETF) is located at the main ring of the HIRFL-CSR. The gamma detector of the ETF is built to measure online gamma-rays with energies below 5 MeV in the center-of-mass frame...
The deep sea contains abundant resources, and it is of great scientific significance to conduct deep-sea exploration. Active neutron detection based on neutron capture or scattering has the advantages of being non-destructive and detecting a wide variety of elements. However, studies on in-situ neutron detection in deep-sea with a neutron source are rare. The capture-type gamma detector based...
The High-Luminosity Large Hadron Collider (HL-LHC), which should begin operation in 2029, aims to increase LHC luminosity by a factor of 10 beyond its original design. In preparation for this increase, the ATLAS experiment has planned a major upgrade program that is split into two steps. During the “Phase-I” step, that will be completed in 2022, several new trigger and detector systems have...
Multiplicity trigger is a method based on measuring the number of fired detector channels after a reaction. And it is a commonly used trigger method in particle physics experiments. The trigger system is usually implemented through hardware, such as NIM modules or FPGA devices. However, the hardware is often deeply bound to the back-end system, and it is difficult to adjust the trigger logic,...
The MircoTCA.4 Fast Control and Processing board (u4FCP) is an FPGA-based double-width MircoTCA.4 compatible Advanced Mezzanine Card (AMC) for generic control and data acquisition applications in high energy physics (HEP) experiments. Built around the Xilinx Kintex UltraScale+ FPGA, the u4FCP provides users with a platform which has access to on-board FPGA Mezzanine Card (FMC) sockets with an...
Abstract—ATLAS [1] calorimeter is formed by individual
detector cells placed in a cylindrical geometry.
Each individual cell will record information when particle
collisions happen and this data is stored to be later processed
by algorithms provided by ATHENA Framework.
One of the main goals of those algorithms is to analyze
the collision events happening inside the calorimeter...
To improve data throughput of the Belle II data
acquisition we are upgrading the CPU-based COPPER system
with a PCIe40 board carrying Arria 10 FPGA. Since one of
the main functionality of the new system is event building in
FPGA, the read-out system must be synchronized with the front-
end electronics. This task is performed by the bidirectional
trigger timing distribution system. During...
