Michael:

Efficiency of array

Rescaled to lead efficiency curve for MB01

Made fits for full energy range (only detectors that reach 6 MeV) and low energy range (all detectors) both including and excluding Ge06 (broke during beam shutdown)

Using covariance matrix gives errors of ~0.5% at 1 MeV and ~3.5% at 6 MeV

Systematics? --> Suggestion Andreas: Take 10% uncertainty in all points

 

Andreas;

Co-56 source will be produced soon. 5 seconds at 50 µA

 

Stella:

Effect of w parameter on Cm-248

No clear improvement in 2p-1s, 6keV offset remains

dR and dQ seem to be independent of w

Fitting 3d-2p and 2p-1s at the same time does seem to help! Relatively large w=1.1, but uncertainty determination still seems weird --> Stella will continue looking into it with Natalia

 

Katharina:

Improving timing of the SDD's

Waveforms look a bit weird, small bumps at rising edge

ELET and fitting haven't really improved the timing

Slow risetimes, can we still do better?
