From roughly 10:45 pm to 11:05 pm,  Sergey tuned the 
ion optics of the ESR to see if the mass resolution at 
413.55735 MHz improves or not. Please note that the 
frequencies of ions during the tuning process are not 
stable.

Q-magnets and S-magnets have been adjusted, see 
accelerator E-logs ID-844 titled ‘ ESR seting for 
204Pt77+’ created by Sergey.
