The ITER Interlock Control System assumes a crucial role in the tokamak operation to protect the machine against failures. Consequently, it must be developed in compliance with the most challenging requirements. The NI CompactRIO technology was chosen by ITER as the FPGA-based platform to develop and implement the investment protection functions, with strict time-constraints. This contribution...
Active feedback control in magnetic confinement fusion devices is desirable to mitigate plasma instabilities and enable robust operation. Optical high-speed cameras provide a powerful, non-invasive diagnostic and can be suitable for these applications. In this study, we process fast camera data, at rates exceeding 100kfps, on in situ Field Programmable Gate Array (FPGA) hardware to track...
This contribution explores the feasibility of using high-level C/C++ like languages to achieve the integration of specilied FPGAs-based applications with the function blocks of the ITER Real-Time Framework (RTF). RTF enables the development, deployment and execution of instrumentation and control (I&C) applications optimized for real-time performance on ITER CODAC Core System. High Level...
The detector of tRopIcal DEep-sea Neutrino Telescope (TRIDENT), hybrid digital optical module (hDOM), employs large-area silicon photomultiplier (SiPM) arrays combined with photomultiplier tubes to boost photon detection efficiency and pointing capability. The experiment requires that the time response of the single photon signal read out by the SiPM array is less than 300 ps (full width at...
The Jiangmen Underground Neutrino Observatory (JUNO) is an important particle physics experiment. The Detector Control System (DCS) in the experiment needs to monitor a lot of indicators, including environmental temperature, humidity and the operational status of electronics hardware devices. This presentation outlines a remote monitoring system, part of DCS, which is based on Experimental...
Photonuclear reactions induced by high-energy photons play a pivotal role in nuclear physics and radiation transport simulation that is used for medical and industrial applications of high-energy photons. In the transport simulation, not only the photonuclear reaction cross section but also the energy distribution of secondary particles, especially neutrons, is essential because the behavior...
CMOS pixel sensors are attractive for the design and construction of the CEPC (Circular Electron Positron Collider) vertex detector due to the low material budget, high spatial resolution, fast readout speed and low power consumption. A series of CMOS pixel sensors were developed for CEPC vertex detector with different study purposes. This study aims to construct a fully functional large-scale...
Hyper-Kamiokande (HK) is a next generation neutrino experiment planed to start in 2027. The detector will be the largest ever water Cherenkov detector with 260kton water tank and more than 20k photomultiplier tubes (PMTs) on the wall. The detector’s large scale and high performance require various challenges on the electronics and DAQ. The design of the HK electronics has been almost...
The KSTAR (Korea Superconducting Tokamak Advanced Research) DPA (Disruption Prediction and Avoidance) project led by Steve Sabbagh and Columbia University established a need for increased real-time diagnostic inputs to the KSTAR PCS (plasma control system) to support the real-time evaluation of DECAF (Disruption Event Characterization and Forecasting) algorithms. Over several years, the DPA...
