S. Date et N. Kumagai, A long-term observation of the DC component of the horizontal COD in the storage ring of SPring-8, NUCL INST A, 421(3), 1999, pp. 417-422
The SPring-8 storage ring is under the operation dedicated to synchrotron l
ight users. The stability of the electron beam orbit during long term opera
tion is one of the main goals to be achieved. Data on the beam orbit taken
for this purpose show variations in time including a very clear signature o
f an effect of the earth tide. (C) 1999 Elsevier Science B.V. All rights re
