  • Yasunobu Arikawa,
  • Yuki Abe,
  • Seyed Reza Mirfayzi,
  • Alessio Morace,
  • Takehito Hayakawa,
  • Tianyun Wei and
  • Akifumi Yogo

The advance of laser-driven neutron sources (LDNSs) has enabled neutron resonance spectroscopy to be performed with a single shot of a laser. In this study, we describe a detection system of epithermal (∼eV) neutrons especially designed for neutr...

New Ballistic Neutron Guide for the Time-of-Flight Spectrometer FOCUS at PSI

  • Fanni Juranyi,
  • Masako Yamada,
  • Christine Klauser,
  • Lothar Holitzner and
  • Uwe Filges

FOCUS is a direct-geometry cold neutron time-of-flight spectrometer at SINQ (PSI, CH). Its neutron guide was exchanged in 2019/2020 within the SINQ Upgrade project, while the rest of the instrument remained unchanged. The new guide provided a signifi...

Spectral Characteristics of Polarization Radiation in the Water Window Range

  • M. V. Shevelev,
  • A. S. Konkov,
  • S. R. Uglov,
  • B. A. Alekseev and
  • Yu. M. Cherepennikov

The high-intensity and monochromatic radiation sources in the water window spectral range are desirable for many applications. One of the potential candidates of soft X-ray sources is polarization radiation produced by a charged particle passing thro...

Helical Electron Beam Status Online Evaluation for Magnetron Injection Gun

  • Wei Jiang,
  • Chaoxuan Lu,
  • Binyang Han,
  • Boxin Dai,
  • Qiang Zheng,
  • Guo Liu,
  • Jianxun Wang and
  • Yong Luo

The magnetron injection gun (MIG) is an essential component of the gyrotron traveling wave tube (gyro-TWT). Although the electron beam status influences the performance of the device, it cannot be measured directly in the experiment. An online evalua...
