The Baby MIND spectrometer is designed to measure the momentum and charge of muons from neutrino interactions in water hydrocarbon targets at J-PARC T59 (WAGASCI) experiment. WAGASCI experiment will ratio charged current interaction cross-sections on aiming reducing systematic errors oscillation analyses T2K. Construction detector within CERN Neutrino Platform framework was completed June 2017, where it underwent full commissioning characterization a particle beam line Proton Synchrotron...
The Level-1 trigger system (TRG) in the Belle II experiment is designed to summarize real-time sub-detectors information by using FPGA chips for central data acquisition (DAQ) system, and it includes several sub-trigger systems triggering various types of physics events interest. main focus this report CDCTRG: track with Central Drift Chamber (CDC) detector, which responsible trajectory reconstruction charged particles algorithms: Track-Segment Finder, 2D, 3D, Neuro-3D, short tracking....
We describe the principles and performance of first-level ("L1") hardware track trigger Belle II, based on neural networks. The networks use as input results from standard II trigger, which provides "2D" candidates in plane transverse to electron-positron beams. then provide estimates for origin 2D direction colliding beams ("$z$-vertex"), well their polar emission angles $\theta$. Given $z$-vertices "neural" tracks allows identifying events coming collision region ($z \approx 0$),...
The SuperKEKB/Belle II experiment aims to collect high-statistics data of B meson pairs explore new physics beyond the Standard Model (SM). SuperKEKB, an upgraded version KEKB accelerator, has achieved a world-record luminosity $4.71 \times 10^{34} \, \mathrm{cm^{-2}s^{-1}}$ in 2022 but continues strive for higher luminosities. One major obstacles is Sudden Beam Loss (SBL) events, which cause substantial beam losses and damage Belle~II detector. To find hint addressing SBL challenges,...
In the Belle II experiment, target of Level-1 trigger system (TRG) is to select various types physics events with high efficiency and limited processing time by using FPGA (Field Programmable Gate Array) chips summarize online information. The utilizes data from Central Drift Chamber (CDC) detector validate real-time charged particle fast tracking algorithms, which critical for some decision conditions in II. paper, we will focus on sub-systems associated CDC introduce hardware design,...
The Belle II experiment at the SuperKEKB electron-positron collider began physics data-taking in 2019 with full detectors. main goal of is to search for new beyond Standard Model heavy flavor decays and Dark sector. In order select events interest efficiently under severe beam background environment from higher instantaneous luminosity run than KEKB collider, we have upgraded a real-time hardware trigger system using CsI(Tl) electromagnetic calorimeter. this report, performance calorimeter...
The level-1 trigger system of the Belle II experiment is designed to select physics events interest with almost 100% efficiency for hadronic events. In terms event timing decision, required have an accuracy less than 10 ns. Central Drift Chamber (CDC) provides information as one sources. We developed new algorithm measure about ns based on CDC hit timing. Two-dimensional charged track reconstruction by Hough transformation was utilized reduce high background hits. used a new-developed...
