Marie:

56Co lines in literature seem to be questionable!

They fitted the double escape peak, which is in substantial overlap with another peak

Another work seems more trustworthy, but they quote 0.5 keV uncertainty --> Not useful for calibration

Remeasure it ourselves? --> Suggestion Andreas: Gold on veto + 56Co may give a decent value

Geant4: Progressing and slowly adding more detectors

 

Michael:

Investigate binning effects on data

Improvement up to 10 bins/keV with statistical error of 8 eV --> 100 bins/keV still seems good

Problem with the convergence of beta and fG --> Go to small values to make the tail a regular gaussian

Try to include a prior to bias likelihood to larger gaussian fractions

Suggestion Andreas: Evaluate what happens without a tail (at different energies, it may not be needed?) and/or evaluate energy dependence of beta

Publication is progressing: MP part is written and DoD part shouldn't take much longer. Andreas will talk to people that made surface targets of gold/chromium/graphite and write a section.

 

Thomas:

Manaslu meeting in April, would like to have someone from muX present the heavy stuff. For Andreas it may be tough, Frederik will check his agenda and see if he can come.

 

Anastasia:

Preparing colloquium

Uranium and thorium are slowly starting to match with Stella's simulations

 

Website:

Should we update the website of muX hosted by PSI?

Perhaps muonic atoms with subcategories muX/ReferenceRadii/Quartet

Get ReferenceRadii and Quartet on experiment list

 

Andreas:

Reference radii will start on thursday after MIXE, end is slightly flexible, but the setup of quartet needs the hallendienst

There are minutes attached to this event. Show them.
