Andreas:

Visit to Heidelberg for g-factor measurements --> Quite some interest in precise measurements with muonic atoms

 

Deadtime issues with monument. O(10%) of events lost. 

When the event bank is full, new events can only be collected when a reset occurs. Worse for higher efficiency detectors

Present in 2021 and 2022 data, can they solve it for this year? Hard to quantify

 

Katharina:

Calibration fitting for lithium is a lot better than last year

No clear muonic nitrogen lines --> Most likely due to aluminum backing leading to little stopping in air

Waveforms sometimes look weird

Events at low energy continuously spread in time --> Weird waveforms?

Another bunch of data points starts 3µs after the muon hit --> Most likely next muon hit, which is protected for small times

 

Michael:

Rescaling efficiency of lines from europium and other sources to lead lines

For 1 detector and 1 group of sources: cut of at log(E)^2

For 1 detector and all sources: cut of at log(E)^3

Seems quite nice for all detectors

How to deal with source activities and other systematics?
