Needed for beamtime:

Some of the Monument detectors: TUM, but not JINR

75% from Leuven at CERN, will come for first MIXE beamtime

Converging on detector purchase in Leuven, 90% to be shipped to canberra for refurbishing soon

Marie and/or Warwar will make a spreadsheet

 

New gas cell to test mossbauer La-137 target. Will be less than 0.01 LA, but Andreas will check with RP

 

Michael:

Paper got some feedback from Andreas, updated some things --> If Andreas is happy we can send it around to the full collaboration

 

Marie:

BR2 proposal send around. Not sure why measuring 108m would be a problem. Comment Andreas: Add some clarity that the metastable state can readily be used for benchmarking as well

 

War war:

La implantation will happen at risico in mainz in autumn rather than at cern --> Not in time for the beamtime this year

Details are being figured out

ReferenceRadii will likely focus on Lu and some tests on the La Mossbauer target

 

Andreas:

What is needed from a calibration point of view?

Co-56 seems not to be as reliable as literature quotes, Pb-208 has the N calibration line which changes --> What is actually reliable

mudirac from Michael:

La ~12keV/% change in mean square radius --> Aim for 0.01% experimental precision --> 0.12 keV

Lu ~25 keV/% change in mean square radius--> Aim for 0.01% experimental precision --> 0.25 keV

 

Perhaps a new Co-56 source would be nice and add the lead. Calibration will need to be looked into for systematics

 

Frederik:

Getting data back from backup isn't quite working yet --> No urgency at the moment

Data visualization in midas: Pushed Stefan Ritt enough to make something midas based

Simple plotting library that forwards data on request

 

Andreas:

Website now has quartet and reference radii pages

External users can edit (Michael checked and it worked)

We can start getting something on there
