Abstract The PANDA (antiProton ANnihilation at DArmstadt) experiment will study the strong interaction in annihilation reactions between an antiproton beam and a stationary cluster jet target. detector be composed of several sub-detectors designed for tracking, particle identification calorimetry. Micro-Vertex Detector (MVD) is innermost part tracking system surrounding region, which precise vertex detection. It consists silicon pixel double-sided microstrip detectors. For readout sensors...
Modern data acquisition and trigger systems require a throughput of several GB/s latencies the order microseconds. To satisfy such requirements, heterogeneous readout system based on FPGA cards GPU-based computing nodes coupled by InfiniBand has been developed. The incoming from back-end electronics is delivered directly into internal memory GPUs through dedicated peer-to-peer PCIe communication. High performance DMA engines have developed for direct communication between FPGAs using...
Modern physics experiments produce multi-GB/s data rates. Fast links and high performance computing stages are required for continuous acquisition processing. Because of their intrinsic parallelism computational power, GPUs emerged as an ideal solution to process this in applications.

Coherent synchrotron radiation (CSR) is generated when the electron bunch length in order of magnitude wavelength emitted radiation. The self-interaction short bunches with their own electromagnetic fields changes longitudinal beam dynamics significantly. Above a certain current threshold, micro-bunching instability develops, characterized by appearance distinguishable substructures phase space bunch. To stabilize CSR emission, real-time feedback control loop based on reinforcement learning...
On-line monitoring of synchrotron 3D-imaging experiments requires very fast tomographic reconstruction. Direct Fourier methods (DFM) have the potential to be faster than standard Filtered Backprojection. We evaluated multiple DFMs using various interpolation techniques. compared reconstruct ion quality and studied parallelization potential.

Given the rapid improvement of detectors at high-energy physics experiments, need for real-time data monitoring systems has become imperative. The significance these lies in their ability to display experiment status, steer software and hardware instrumentation, provide alarms, thus enabling researchers manage experiments better. However, typically build most as standalone in-house solutions that cannot be reused other or future upgrades. We present BORA (personalized collaBORAtive display),...
The commissioning and operation of future large-scale scientific experiments will challenge current tuning control methods. Reinforcement learning (RL) algorithms are a promising solution thanks to their capability autonomously tackling problem based on task parameterized by reward function. conventionally utilized machine (ML) libraries not intended for microsecond latency applications, as they mostly optimize throughput performance. On the other hand, most programmable logic...

In this work, we investigate the use of GPUs as a way realizing low-latency, high-throughput track trigger, using CMS showcase example. The detector at Large Hadron Collider (LHC) will undergo major upgrade after long shutdown from 2024 to 2026 when it enter high luminosity era. During upgrade, silicon tracker have be completely replaced. High Luminosity operation mode, luminosities 5–7 × 1034 cm−2s−1 and pileups averaging 140 events, with maximum up 200 reached. These changes require update...
The detection of rapid dynamics in diverse physical systems is traditionally very difficult and strongly dominated by several noise contributions. Laser mode-locking, electron bunches accelerators optical-triggered phases materials are events that carry important information about the system from which they emerge. To understand underlying complex often large numbers single-shot measurements must be acquired continuously over a long time with extremely high temporal resolution. Ultrafast...
