Beam intensity started at 20 enA, went to 8.5 enA and keep decreasing (up to 3enA), wriging ~5.3 KiB/s
Intensity dropped to 3enA, Hakim came and increased it back to 20enA from subrun 24-25 onward.

|
PAY attention to the stripper foil.
If the beam intensity drops to 15 enA, check the stripper foil.
It should be ~5 enA after the target (the meter on the counter) |

|
at 00:40 beam intensity dropped to ~ 9enA . We increased the beam intensity by changing a stripper foil which resulted in 40 enA (~ 250 c in strip 1
counter in DSSD) (KWL and JSP).

beam was found and is back....but 60Ni seems to not be there.....more like 58Ni....(red compared to blue)
I have called hakim back...who just left
