Andreas:
Preparation for experiments:
Miniball need positive bias --> Use Randolf's module for extra channel(s)
LN2 system is ready
Found cables with 16 ns and 64 ns delay
Neutron detectors --> Frederik will arrange this
Entrance scintillators in the workshop
Updated slow control box for gas system
Gas bottles have arrived
Poly-ethylene will be attached to the titanium grid to minimize its background (Katharina)
Targets:
Surface targets for gold reference will be arranged --> Masses from the document have been checked (they were correct)
Lithium target being prepared with MIXE collaboration --> Katharina will follow up on this
Barium being prepared in Mainz: Molecular plating Vs. Drop-on-demand
Potassium reference? Current plan is Cr, but Michael will try to look for CVD alternatives
Michael:
RBS on Surrey samples:
Seems to be quite a bit less than expected (~factor 4-5)
RBS expert will look at the spectra to check for major mistakes --> Michael will follow up on this
Potentially due to porosity of glassy carbon
Neutron analysis:
Calibrating on Compton edges
~1600 keVee at ADC channel 500
High energy Compton continuum? Most likely Cosmic particle/coincidence event/...
Frederik:
DAQ development:
(my internet was acting up a bit so it would be nice if someone can fill this part)
Stella:
Curium 2p-1s:
Natalia managed to introduce the magnetic part of the hamiltonian, but it shows no effect --> Not really possible, so trying to resolve that --> Stella will follow up on this
Curium 3d-2p:
Predictions aren't matching
A lot of background from Palladium contamination
NP has not yet been included --> Stella will follow up on this.
Nilesh:
Trying to calculate the population levels of 2s & 2p
How much goes from 2s to 2p
Currently 1/3 is missing from/to the 2p state? Seems too much
Will look into muon cascade code --> Nilesh will follow up on this
Katharina:
Looking at the silicon drift detector
Covering titanium grid with poly-ethylene
Callibration, behavior, ...
