Preliminary design of continuous wave Low-Level RF systems for S3FEL
Z. Y. Zhang, J. F. Zhu, H. L. Ding +4
In the Shenzhen Superconducting Soft X-ray Free Electron Laser (S3FEL), Continuous Wave (CW) Low-Level Radio Frequency (LLRF) systems perform critical functions including adjusting…
MAGI-1: Autoregressive Video Generation at Scale
Sand. ai, Hansi Teng, Hongyu Jia +36
We present MAGI-1, a world model that generates videos by autoregressively predicting a sequence of video chunks, defined as fixed-length segments of consecutive frames. Trained to…
Low-level radiofrequency system upgrade for the Dalian Coherent Light Source
H. L. Ding, J. F. Zhu, H. K. Li +4
DCLS (Dalian Coherent Light Source) is an FEL (Free-Electron Laser) user facility at EUV (Extreme Ultraviolet). The primary accelerator of DCLS operates at a repetition rate of 20…
A low-delay reference tracking algorithm for microwave measurement and control
J. F. Zhu, H. L. Ding, H. K. Li +5
In FEL (Free-Electron Laser) accelerators, LLRF (Low-Level Radiofrequency) systems usually deploy feedback or feedforward algorithms requiring precise microwave measurement. The sl…
The microwave amplitude and phase setting based on event timing for the DCLS
J. F. Zhu, H. L. Ding, H. K. Li +6
The primary accelerator of DCLS (Dalian Coherent Light Source) operates at a repetition rate of 20 Hz now, and the beam is divided at the end of the linear accelera-tor through Kic…
Implementation of microwave with arbitrary amplitude and phase for the DCLS
H. K. Li, H. L. Ding, Y. Li +5
In many experiments, the simultaneous emission of multiple wavelengths of FEL (Free-Electron Laser) is significant. For the pulsed-mode FEL facility, we must accelerate multiple el…
An Intra-pulse feedforward algorithm for improving pulsed microwave stability
J. W. Han, H. L. Ding, J. F. Zhu +4
During the pulsed operation of the linear accelerator in DCLS (Dalian Coherent Light Source), we found a strong correlation between the klystron modulator's high voltage and the kl…
Probing the nature of the conjectured low-spin wobbling bands in atomic nuclei
S. Guo, X. H. Zhou, C. M. Petrache +28
Precession is a unique motion in which the orientation of the rotational axis of a rotating body is not fixed but moving, and it generally exists in the Universe from giant stars t…
Spectroscopic factor and proton formation probability for the d3/2 proton emitter 151mLu
F. Wang, B. H. Sun, Z. Liu +42
The quenching of the experimental spectroscopic factor for proton emission from the short-lived isomeric state in Lu was a long-standing problem. In the present…
Generating polarization controllable FELs at Dalian coherent light source
T. Zhang, H. X. Deng, D. Wang +5
The property of the FEL polarization is of great importance to the user community. FEL pulses with ultra-high intensity and flexible polarization control ability will absolutely op…
