Injector Status • The Rb temperature was scan on Friday. The Booster input intensity

Injector Status • The Rb temperature was scan on Friday. The Booster input intensity was varied by Rb temperature from 6. 7 -12 E 11. The source polarization changed from 82% to 86%. AGS polarization is also higher with lower Booster input. The Booster input was put as 6. 7 E 11 since fill 20702. Jet polarization shows higher polarization since Friday night. • Source polarization is higher with lower intensity. • J 5 jump quad tripped on LV PS fault on Monday, Wednesday (twice). I lowered the LV PS set value below 40 V limit on Thursday. J 5 tripped again on Sunday. The function is not a smooth function. Probably it should be smoothed. • We have lost three polarimeter targets in AGS. Target replacement will be done tomorrow. • NSRL run starts this week. The setup has been done last week. • Zirconium ions 90 Zr 15 and 96 Zr 16 from EBIS were injected and accelerated in the Booster. Both isotopes extracted into R-line to confirm their mass and charge. We need to think how to separate them for AGS, probably in Bt. A line. Haixin 6 Huang
