    Launch &

- The construction of PAL-XFEL, a 0.1nm hard X-ray FEL facility consisting of a 10-GeV S-band linac have been completed in the end of 2015. FEL-XFEL achieved 0.1 nm hard X-ray on the 29th November, 2016. - Comparative advantages in 21st century state-of-the-art science field, according to the construction of X-FEL accelerator and 3 beamlines. ( XSS(X-ray Scattering & Spectroscopy), NCI(Nano Crystallography & Coherent Imaging), SSS(Soft X-ray Scattering & Spectroscopy)) - In order to accomplish new researches using the 4th-generation synchrotron radiation accelerator, which is the third in the world, we focus on all the capabilities of the institute.
Application Area
- The 21st century science is diverted with femto(One in 1,000 trillion seconds) and nano(One billionth of a meter). So, the X-FEL enables to real-time observation of phenomena occurring in living cells and inner material with 10 billion times brighter than 3rd generation synchrotron radiation. - Making the breakthrough in high-tech industry, such as BT and pharmaceutical Industry, IT and semiconductor industry. (Femto-second photon-matter interaction dynamics, nano-crystal/bio-sample X-ray imaging)
