| Research Abstract |
This project pursues the photon-flux enhancement of a high harmonic beamline upto the flux of the synchrotron facility SPirng-8. The beamline is based on a time-delay compensated monochromator, selecting a single harmonic with the pulse duration preserved. The photon flux was increased by exploiting phase match for high harmonic generation inside a hollow fiber filled with rare gas as nonlinear medium. The photon flux on target was 7×109 photons/sec at the 19th harmonic (=29.6 eV), comparable to that of UV-SOR. Furthermore, the photon flux was enhanced by 10 times by using one grating at the 0th order reflection, although the pulse duration became 200 fs. Consequently, the high harmonic beamline comparable to SPring-8 was successfully developed.
