Accelerator engineering could benefit from faster and higher-quality physics simulations. Machine learning has emerged as a promising tool for developing accelerator simulation programs that are both fast accurate. In this study, we propose surrogate model based on encoder–decoder neural networks. We incorporate physical regularization into the loss function, which allows us to integrate prior knowledge deep network. The advantage of is it ensures results more consistent with underlying...
Neural network-based surrogate models can provide fast, reliable and realistic of accelerators. However, training a model from start-to-end is still challenge. For accelerators with dozens or even hundreds elements, lead to dimensional disaster. In this paper, we use dual network polynomial neural networks (PNNs) long short-term memory (LSTM) nested structure realize China Accelerator Facility for Superheavy Element (CAFe2). Results show that the PNN–LSTM effectively CAFe2. Compared running...
The high availability of Accelerator-Driven Sub-critical system (ADS) facilities poses a major challenge for the accelerators, which sets stringent requirements on beam trip rate. However, trips caused by component failures in low-energy region superconducting (SC) radio-frequency (RF) cavity are always bottleneck long-term stable operation high-power beams. In this paper, we present compensation method. This method can be used to compensate faults that occur at ([Formula: see text][Formula:...
