Cafe neutrino meeting minutes (16/12/2010)
Present: C. Hansen, E. Wildner, G. Prior

Agenda:
- News and Discussions (round table)

Round-table:


From G. Prior,
The final draft of the Neutrino Factory Intermedery Design Report (IDR) for ISS report is ready.
However results from simulations about the pion production from the mercury target are not included.
Will send comments before 24th December to suggest to include a bigger CERN part.


From Elena Wildner,
Preparing EUROnu RAL meeting.
Have become responsible to organize Marie Curie Initial Training student visits to CERN to
study physics about 'invisibles' (neutrinos and dark matter).


From Christian Hansen,
Trying to figure out solutions for the Collective Effect limitations for the Decay Ring beyond the FP6 design.
40 bunches (with half the bunch length) instead of 20 were no improvement, nor so was increasing the pipe radius.
Now trying the decrease the effect of Transversal Broad Band Impedance by decreasing the gamma-transition.
Antoine promised he would check if he could make a lattice with high dispersion at the dipoles in the arcs.
However, decreasing gamma-transition from 27 to 15 means the voltage have to increase from 11 to 41 megavolt.

Next meeting:
13th January 9am - next cafe-neutrino meeting (room tbc).
