-> we are trying to get PID with a new setting
to see if 98Zr decays with 30s half-life

see attached setting!

  72   Fri May 17 17:09:26 2024 Helmut, YuryAcceleratorapprox. 96Sr setting (98Zr39+)Only 96Sr would yield very few line with only
ions from time to time.
So we went a bit lower in Brho 7.69 Tm ->
