Bayesian Calibration of Accelerator Digital Twin with ML
US & West ·
Bayesian methods were used to calibrate the digital twin of a particle accelerator at the AGS Booster at Brookhaven National Laboratory. Multiplicative parameters were introduced to quadrupole transfer functions to account for hard-to-measure effects. A machine learning emulator trained on an ensemble of Bmad simulations accelerated the inference.
Why it matters
Calibrating models of physical systems against measurement data is key for building trustworthy digital twins.
В Северной Осетии активно внедряют умные технологии для контроля дорожной сети. Камеры фиксируют нарушения, на трассах работают пункты весогабаритного контроля, а во Владикавказе создаётся цифровой двойник города. Пассажиры смогут отслеживать движение трамваев в приложении.
Evaluating 5G positioning on a physical testbed ties every measurement to one propagation environment and one antenna layout, so any question about an alternative deployment requires a new field campaign.
Industrial environments are increasingly characterized by the tight interaction among physical processes, communication infrastructures, and intelligent applications. In this context, Digital Twins (DTs) have emerged as a key technology for system analysis and optimization.
