Tue Jun 20 21:22:21 2023, KHK, KWL, Problems, , Other, contamination in the chamber
|
We see the the background lines coming probably from some activation inside the chamber as the target wheel is removed and we run only
with the alpha source at the moment.
The spectrum is the same means that something inside the chamber is activated, not the target 197Au used in the coulex run or neither it's |
|
Sun Jun 18 19:24:19 2023, All, Other, , Other, change the foils every ~2 hours
|
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) |
