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…
LHAASO-KM2A detector simulation using Geant4
Zhen Cao, F. Aharonian, Q. An +275
KM2A is one of the main sub-arrays of LHAASO, working on gamma ray astronomy and cosmic ray physics at energies above 10 TeV. Detector simulation is the important foundation for es…
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…
An Ultrahigh-energy -ray Bubble Powered by a Super PeVatron
The LHAASO Collaboration, Z. Cao, F. Aharonian +277
We report the detection of a -ray bubble spanning at least 100 in ultra high energy (UHE) up to a few PeV in the direction of the star-forming region Cygnus X, implyi…
