PF-AR Storage Ring
PF-AR(Advanced Ring for pulse X-rays), which was originally
the booster synchrotron of TRISTAN electron-positron collider, is now operated
as a dedicated synchrotron light source with the electron beam of 6.5 GeV. In
PF-AR there are seven beam lines, AR-NE1, -NE3, -NE5, -NW2, -NW10, -NW12, and
-NW14. AR-NE1 has an elliptically polarized multipole wiggler, while AR-NE3,
-NW2, -NW12, and -NW14 have X-ray undulators. AR-NE5 and AR-NW10 accept synchrotron
light from bending magnets in
the normal cell.
