October 30, 1997

• Tune survey (1:10 - 5:27 AM).
• Orbit correction data for the insertion devices (MPW#19 and EMPW#28) was collected (10:11 AM - 6:00 PM). Correction data for three sets of magnets (A, B, C) of MPW#19 and for three operation modes (EWP, EWN and LYP; see notes below) of EMPW#28 were taken.
• Test on the orbit feedback system was carried out (6:03 PM - 2:15 AM, Oct. 31).
• Operational data in this morning:
  

  Time	Beam current	Beam lifetime	I*tau	Average pressure	Integrated current
  9:15 AM	392.9 mA	430 minutes	169 A*minutes	0.66 nTorr	175.2 A*hours

(Note) Some operational modes of the elliptically-polarized multipole wiggler EMPW#28
EWP: Elliptically polarized - Wiggler - Positive helicity
EWN: Same as above, but with negative helicity
LYP: Linearly polarized - Y axis - Positive

Beam current (blue line) and beam lifetime (red line) around the clock.
