6D and High Dynamic Range Measurements of Hadron Beam Phase-Space | ||||
|
|||||
| Over last several years, the SNS Beam Instrumentation Group has made significant progress in developing instrumentation to measure and characterize hadron beam distribution with accuracy and resolution sufficient for model-based understanding and mitigation of beam loss in high power hadron linacs. This includes measurement of the beam distribution in high dimensional phase-space to provide realistic initial conditions for particle tracking, and high dynamic range to measure the beam halo. This presentation will describe the latest results from the SNS Beam test facility: measurement of the 6-dimensional phase space with dynamic range sufficient to reveal features not previously observed; 2-dimensional phase-space measurements with 106 dynamic showing emergence of the beam halo; and, in between, the 5-dimensional measurements with sufficient dynamic range and resolution to generate realistic distribution of 10-100 million particles for tracing codes. | |||||

Machine Learning-Assisted Beam Operation at SuperKEKB and Linac at KEK | ||||
|
|||||
| Hundreds to thousands of tuning parameters must be optimized for each operating condition to obtain the best performance from an accelerator. In the past, experts made decisions based on their experience on which tuning parameters contributed the most to the performance and adjusted them sequentially. On the other hand, accelerator tuning approaches based on machine learning, which has become much easier to handle, have been studied intensively in recent years. We have been developing a beam-tuning tool based on Bayesian optimization for boosting the SuperKEKB accelerator. In this presentation, we will report on the latest status of the beam test of the positron-beam-yield maximization and dispersion tuning at the KEK injector as the first development step. | |||||

| TH2C03 | Analysis of the Transverse Schottky Signals in the LHC | 462 | |||
|
|||||
| Schottky-based diagnostics are remarkably useful tools for the non-invasive monitoring of hadron beam and machine characteristics such as the betatron tune and the chromaticity. In this contribution recent developments in the analysis of the transverse Schottky signals measured at the Large Hadron Collider will be reported. A fitting-based technique, where the measured spectra are iteratively compared with theoretical predictions, will be presented and benchmarked with respect to the previously known methods and alternative diagnostic. | |||||
