Popis:	The Photon Factory (PF) storage ring is a dedicated synchrotron radiation source. The stability of photon beams is the most important subject regarding such sources, since accurate positioning is especially required for sharply pointing undulator beams. A modification to increase the brightness by reducing the emittance of the circulating beams was carried out in 1987 at the PF ring. Though significant upgrades in the brightness have been obtained, many difficulties have simultaneously arisen, such as an increase of beam instabilities and photon‐beam drifts. Stabilizing efforts have been carried out and great progress has been made: building distortion due to thermal stress, reduced to 1/6 by thermally insulating the roof.
