Damage threshold and focusability of mid-infrared free-electron laser pulses gated by a plasma mirror with nanosecond switching pulses
Xiaolong Wang, Takashi Nakajima, Heishun Zen +2
The presence of a pulse train structure of an oscillator-type free-electron laser (FEL) results in the immediate damage of a solid target upon focusing. We demonstrate that the las…
Diagnosis of the Wavelength Stability of a Mid-Infrared Free-Electron Laser
Xiaolong Wang, Yu Qin, Takashi Nakajima +3
Wavelength stability of free-electron lasers (FELs) is one of the important parameters for various applications. In this paper we describe two different methods to diagnose the wav…
Single-shot spectra of temporally selected micropulses from a mid-infrared free-electron laser by upconversion
Xiaolong Wang, Takashi Nakajima, Heishun Zen +2
We demonstrate the measurement of single-shot spectra of temporally selected micropulses from a mid-infrared (MIR) free-electron laser (FEL) by upconversion. We achieve the upconve…
New Constraints on Radiative Decay of Long-Lived Particles in Big Bang Nucleosynthesis with New He Photodisintegration Data
Motohiko Kusakabe, Toshitaka Kajino, Takashi Yoshida +3
A recent measurement of He photodisintegration reactions, He(,)H and He(,)He with laser-Compton photons shows smaller cross sections than those esti…
Simultaneous measurement of the photodisintegration of 4He in the giant dipole resonance region
T. Shima, S. Naito, Y. Nagai +6
We have performed for the first time the simultaneous measurement of the two-body and three-body photodisintegration cross-sections of 4He in the energy range from 21.8 to 29.8 MeV…
Non-resonant direct p- and d-wave neutron capture by 12C
T. Kikuchi, Y. Nagai, T. S. Suzuki +5
Discrete gamma-rays from the neutron capture state of 13C to its low-lying bound states have been measured using pulsed neutrons at En = 550 keV. The partial capture cross sections…
