keyword=beam energy fluctuationStarting at about 00:14, observe a sudden and significant fluctuation in beam energy as displayed by the StripTool utility (note that its clock seems to be about 10 minutes ahead of real time). The hac_bcm_average is about 4525.25+-0.06 (compared to
4525.00+-0.03 before). The IPM1C12.XPOS is also changed and shows -0.20+-0.30 (compared to 0.00+-0.06 before). The situation persists for about
22 minutes, after which values return to previous ballparks.
