The Korean Neutrino Observatory (KNO) has been proposed as the next generation neutrino detector in Korea. The main scientific goals of KNO are the discovery of CP violation in neutrino sector and the observation of cosmic neutrinos. This article gives a brief overview of neutrino physics and introduce the status and prospects of the KNO project.

We introduce on ultrafast electron diffraction (UED) technology that observes the movement of fast-moving atoms. Recently the Korea Atomic Energy Research Institute has built the fastest electron diffraction facility in the world with the achievements of increasing beam brightness and improving temporal accuracy with jitter-free technology. We introduce the unique characteristics of the device with 90-degree-bending structure and conclude with the current status and prospects of the UED and its applications.

HANARO, the only large-scale multipurpose research reactor in Korea, houses the neutron research facility with a diverse set of scientific instrumentation. After a long hiatus marred by trips and the following lengthy shutdowns, HANARO is now back on track. With the addition of the cold neutron source, new cold-neutron instruments are available with the previously operating thermal-neutron beam lines, making the total available neutron scattering instruments to users 9. While there is a plan to add an in-beam Mossbauer instrument and a Positron-annihilation spectrometer in the future, the focus is on recovering the user base at the moment. Achieving stable operation in the currently not-so-favorable regulatory environment remains a big challenge for the research facility.

Lasers have been versatile tools to investigate physical phenomena and they have paved the way for exploring novel physics. Recently, scientists have become excited about the advent of the ultra-intense laser with extreme output power. The output power of the ultra-intense laser will soon reach multi-10 PW and thus, it can provide opportunities to explore novel physics such as photon-photon interaction and vacuum behavior in the strong laser field. Currently, a large ultra-intense laser facility has been pursued in Korea. Here, the current status, applications, and prospects of the ultra-intense laser facility are introduced.
