Michael:
Made an animation for the radon being flushed out of the gas cell after decay with corresponding graphs (see slides if you want to use it)
Idea for improving ELET: Naive algorithm can work better than exact extrapolation, but this corresponds to extrapolating to a different value
--> What if we extrapolate to a value below zero with a third parameter? Risetime gives an indication of the shift due to non-linearity --> Quick simulation (based on e^t/tau - 1 pulses) looks good but still need to do on pulses from the data
Katharina:
SDD timing: weird broad time structure (~1.3 µs total width) with double hump
ELET and template fitting didn't seem to work, but maybe cutting some events based on chi2 could improve a bit
Several microseconds for charges drifting around is likely the cause for bad timing
Marie:
Test collection with Ag-110m as electronic equivalent for Ag108m
Compared lasers on 110m side peaks and a bit further outward (109 has it's resonance at the centroid)
Efficiency seemed reasonable and purity O(1-5%) for different collection conditions --> Quite good since we started from a relative ratio of ~1e-7
Stella:
Talked with Mia Au at ISOLDE about collecting radium. Ionization efficiency is good, but no clue about extraction efficiency.
We could do a test this winter physics to quantify and collect for a target next winter physics for an actual Ra-226 target for muX --> To be discussed more
