Wake Field Effect on the SASE Performance of PAL XFEL / Oh, Jong-Seok ; Lee, Tae-Yeon ; Namkung, Won ; Soo Ko In
The PAL XFEL will supply coherent radiations from VUV to X-rays. X-ray FEL for 0.3 nm lasing requires a 3-GeV driver linac and a 60-m long in-vacuum undulator with a narrow variable gap. [...]

Operational Experience of Cooling Water Systems for Accelerator Components at PLS / Kim, Kyungryul ; Kim, Hyung-Gyun ; Kim, Young-Chan ; Lee, Bongho ; Sik Han, Hong ; Soo Ko In ; Wha Chung, Chin
The cooling water system has been utilized for absorbing heat generated by a multitude of electromagnetic power delivering networks at PLS. The separate cooling water distribution systems for the storage ring, beam transport line and linear accelerator have been operated with a different operating temperature of supplying water. [...]

Recent Experiment Results on Fast Ion Instability at 2.5 GeV PLS / Kim Eun San ; Han, Yeung-Jin ; Hukuma, Hitoshi ; Ikeda, Hitomi ; Park, Chong-Do ; Park, Sung-Ju ; Soo Ko In ; Yun Huang Jung
We present recent experiment results on the fast ion instability that were performed at the PLS storage ring. With higher vacuum pressures of three orders of magnitude than nominal one by He gas injection into the ring, increases of a factor of around three in the vertical beam size were observed by interferometer system.

Design Considerations for the Stability Improvement of Klystron-Modulator for PAL XFEL / Oh, Jong-Seok ; Han, Yeung-Jin ; Namkung, Won ; Soo Ko In ; Soo Park, Soung
The PAL linac is planed to be converted to a SASE-XFEL facility (PAL XFEL) that supplies coherent X-rays down to 0.3-nm wavelength. PAL XEL requires a 3-GeV driver linac and a 60-m long in-vacuum undulator to realize an X-ray SASE-FEL. [...]

Status of PPI (Pohang Photo-Injector) for PAL XFEL / Park, Sung-Ju ; Kim, Changbum ; Oh, Jong-Seok ; Park, Chong-Do ; Park Jang Ho ; Soo Ko In ; Wang, Xijie ; Woon Parc, Yong
A X-Ray Free Electron Laser (XFEL) project based on the Self-Amplified Spontaneous Emission (SASE) is under progress at the Pohang Accelerator Laboratory (PAL). One of the critical R&D; for the PAL XFEL* is to develop the Pohang Photo-Injector (PPI) which is required to deliver electron beams with normalized emittance < 1.5 mm-mrad. [...]

Femtosecond Electron Diffraction and its Application for Beam Characterization at the PAL / Xiang, Dao ; Ihee, Hyotcherl ; Park, Sung-Ju ; Soo Ko In ; Wang, Xijie
Electron diffraction is widely used in electron microscopy to obtain ultrahigh magnification factor, or crystallography to determine the internal structure of the molecule. High energy electron (MeV) has been used to probe the solid state thick sample, now being explored for femto-second electron diffraction (FED) to determine the transient structure of the molecule.
