The FLUKA C.R. libraryDedicated FLUKA library additional off-line packages including:Primary spectra from Z 1 to Z 28 (derived from NASA and updated tomost recent measurements). Other primary flux choices can be added by theuser (Agrawal-Stanev-Gaisser-Lipari flux. All nucleon spectrum).Solar Modulation model(correlated to neutron monitors)Atmospheric model (MSISMass-Spectrometer-Incoherent-Scatter)3D geometry of Earth atmosphereGeomagnetic modelmodulated for a given date,location according to geomag.model, solar modulationFLUKA: superpositionmodel nucleon-AirinteractionFLUKA DPMJET: fullN-Air interactions
(3D) Calculation of Atmospheric n FluxThe first 3-D calculation ofatmospheric neutrinos was donewith FLUKA.The enhancement in thehorizontal direction, whichcannot be predicted by a 1-Dcalculation, was fullyunexpected, but is now generallyacknowledged.In the figure: angulardistribution of n , n ,, ne, neIn red: 1-D calculation

Geometry input format The input file format for the geometry is different from the one adopted anywhere else in FLUKA (i.e. the number and length of the input fields is different) Different formats can be used (due to backward compatibility) Fixed format Alignment is mandatory Bodies and regions are identified by numbers (rather than names), this makes geometry editing
Beginners FLUKA Course. 2 Why User Routines zFluka offers a rich choice of options for scoring most . Useful for initialisation: ie reading and manipulating data from one or more files, calling other private routines, etc. The calling parameters can be used by the user to pass
The agenda title and heading should be similar to the council meeting minutes in format and should: a. State that it is an agenda b. Name the Municipality c. Show the date, time and place of the meeting for which the agenda is issued. Acceptance of the Agenda The agenda for a council meeting is not binding unless it has been adopted by a
