Analysis discussion meeting

Europe/Zurich

Michael:

Update on the neutron-photon PSD

Slight dependence on energy on the maximum location in the FOM --> Use a fixed window for all

Best FOM at the same values for different detectors/runs

PSD plots for overflow events --> Michael will follow up on this

Bayesian analysis of events (when flag --> probability of being a neutron)

Requires P(flag|Neutron) and P(flag|Photon)

 

Stella:

Recap curium-248 analysis

Fit using new inputs from Natalia on charge radii and quadrupole moments

No real improvements on the fits --> Other effects cause the remaining shifts

Dipole moment effects --> Thomas will follow up on this

 

Thomas:

Cm-248 QRPA

Talking with Thomas Duguet from CEA Saclay

Generalization of QRPA should allow for Even-Even nuclei to be calculated --> Ideal for Cm-248

Thomas (Cocolios) will follow up with Thomas (Duguet) on this

 

Andreas:

Working on the estimates for low-Z nuclei (Li and Be)

Magnitude of effects such as electron screening

Microcalorimeters: contact with Heidelberg, collaboration in the near future

 

Frederik:

MIXE collaboration is working on GEANT4 simulations

Think about combining GEANT4 with spectrum generation code

Looking at the importance of self-absorption (more important for MIXE people)

 

DAQ: everyone should get a PSI account to access the DAQ

More people involved with setting up the DAQ --> Michael and Frederik will discuss this after 07/06

 

General beam time discussion:

Campaign starts week 36 after the MIXE campaign --> More tuning after MIXE

INPC during beamtime --> Andreas was invited to speak (not present for week 37)

Setting up the DAQ --> Frederik will be for sure present the first week of the beamtime (hopefully have everything up and running after that)

Thesis writing --> Stella can only assist at the beamtime if time allows for it

Shift monkeys --> Silvia Bara, Jake Johnson, and Wiktoria Wojtaczka will help in the campaign after the LISA school

Beam shutdown in week 37: More finetuning of the HPGe's and Calibration runs

There are minutes attached to this event. Show them.
