A neural network model of a quasiperiodic elliptically polarizing undulator in universal mode

open access: yesJournal of Synchrotron Radiation, 2022
Machine learning has recently been applied and deployed at several light source facilities in the domain of accelerator physics. Here, an approach based on machine learning to produce a fast-executing model is introduced that predicts the polarization ...

Optical performance of LPP multilayer collector mirrors

open access: yes, 2022
Paper 832217The usable power and the collector optics lifetime of high-power extreme ultraviolet light sources at 13.5 nm are considered as the major challenges in the transitioning of EUV lithography from the current pre-production phase to high volume ...

Extreme Ultraviolet Frequency Comb Metrology [PDF]

open access: yesPhysical Review Letters, 2010
The remarkable precision of frequency comb (FC) lasers is transferred to the extreme ultraviolet (XUV, wavelengths shorter than 100 nm), a frequency region previously not accessable to these devices. A frequency comb at XUV wavelengths near 51 nm is generated by amplification and coherent upconversion of a pair of pulses originating from a near ...

Operation of a free-electron laser from the extreme ultraviolet to the water window [PDF]

open access: yes, 2007
We report results on the performance of a free-electron laser operating at a wavelength of 13.7 nm where unprecedented peak and average powers for a coherent extreme-ultraviolet radiation source have been measured.

A dual P‐layer 4H‐SiC p‐i‐n photodetector for the detection from extreme ultraviolet to ultraviolet‐A

open access: yesElectronics Letters, 2023
A dual P‐layer 4H‐SiC p‐i‐n ultraviolet photodetector is proposed and studied. The modeling results of the photoelectric characteristics demonstrate the dual P‐layer structure could effectively reduce the recombination of the photogenerated carriers and ...

Electrostatic chucking of EUVL masks: Coefficients of friction

open access: yes, 2022
Art. 76362JIn extreme ultraviolet lithography (EUVL), the mask hangs on an electrostatic chuck and is moved laterally during exposition. For proper control of the chucked mask under corresponding inertial forces, static friction of the mask on the chuck ...
