Abstract The theory of tune feedback correction and the principle a algorithm based on machine learning are introduced, with focus application lasso regression for correction. Simulation verification online results presented. show that, after applying learning, accuracy system was higher, betatron stability further improved.
Abstract Machine learning (ML) has become a valuable tool in particle accelerator control, with growing potential for beam parameter correction. In this study, we present preliminary ML applications at HLS-II, using Lasso regression online tune correction and neural network (NN) beta function simulation Both models were trained supervised on measured data, while an improved genetic algorithm optimized the NN structure. Our results show that ML-based approach achieves competitive quality...
Taiwan Photon Source (TPS) is a synchrotron radiation facility of medium energy, 3 GeV, and low emittance, under construction at National Synchrotron Radiation Research Center (NSRRC). The multipole errors lattice magnets were rigorously examined corrected so as to maintain the dynamic aperture electron beam in storage ring. fully inspected both vendor vendee sites. tested corrected. In particular, sextupole have pole position adjusted correct conform specification. yoke cutting octupole...
In view of the current demand multi-component gas detection, we develop a detection device base on embedded system. The module is designed TDLAS laser technology, VCSEL and wavelength modulation technology (WMS). has its advantages low working current, small volume high integration, which can effectively reduce improve integration. WMS accuracy sensitivity module, enhance system performance. For data processing, program by using iMX6 Linux system, used for processing result calculation...
A 3-pole gradient-damping wiggler (GDW) was developed for the ALPHA storage ring at Indiana University. The GDW is effective in modifying momentum-compaction factor and damping partition number ring. yokes of are made by lamination silicon steel sheets (50CS1300) with a thickness 0.5 mm. Glue (3M 2216) used to paste together create block using punch fixture. C-shape structure pole profile wigglers cut from silicon-steel blocks wire-cutting machine. One middle two outer poles assembled on...
