4. Alfredo Ferrari, Milan 9/7/20104 Summary of status of the developments (completed)  LPM effect in pair production (completed) (completed)  Time scoring in USRYIELD (completed) (ongoing, for the release??**)  Improvements in the Fermi breakup (ongoing, for the release??**) (started, it should be completed for the release)  Porting DPMJET-3, rQMD, BME to g95/gfortran (Mac, Linux) (started, it should be completed for the release) (ongoing, for the release??**)  Improvements in DPMJET-2.5 (charm production, by Hannes), Toni -> testing (ongoing, for the release??**) (ongoing, for the release quadric only)  New bodies in geometry (torus, generic quadric etc) (ongoing, for the release quadric only) (started, not for the release)  Improvements in the hadronization (started, not for the release) (ongoing, for the release??**)  New, PEANUT based, coalescence including bound particles (ongoing, for the release??**) (started, maybe d for the release??**)  New, PEANUT based, d, t, 3 He, α interaction model at low energies (started, maybe d for the release??**)

5. Alfredo Ferrari, Milan 9/7/20105 Summary of status of the developments (almost completed, for the release, still some problems?*)  What about the Cosmic Ray package (Silvia) (almost completed, for the release, still some problems?*) (almost completed, for the release)  Revised cross sections for d,t, 3 He, 4 He (almost completed, for the release) (ongoing, for the release??**)  Metastable states in low energy neutron library (ongoing, for the release??**) (ongoing, not for the release)  Annihilation photon acolinearity (ongoing, not for the release) (started, it must be completed for the release)  Documenting all new features (started, it must be completed for the release) (started, it must be completed for the release)  Testing the “new” compilers (started, it must be completed for the release)

6. Alfredo Ferrari, Milan 9/7/20106 ICRU predefined materials: reminder  9 standard ICRP/ICRU compounds of biological interest have been predefined:  Water: WATER  Polystyrene: POLYSTYR  Plastic Scint.: PLASCINT  PMMA: PMMA  Compact Bone: BONECOMP  Cortical Bone: BONECORT  Skeletal Muscle: MUSCLESK  Striated Muscle: MUSCLEST  Adipose Tissue: ADTISSUE  Electronic (and nuclear) stopping power for these materials now strictly follows the ICRU numbers even at very low energies  Those materials can be used in an input by name, simply “naming” them (eg with ASSIGNMAT), with no need to define them explicitly!  If a user defines a material of similar name and compoistion the code automatically “matches” it to the predefined one and uses all relevant predefined parameters/stopping power  Sternheimer, I, etc parameters are predefined, and used when a matching is found. They can still be changed through MAT-PROP

7. Alfredo Ferrari, Milan 9/7/20107 What to do for the release? Options…  Make a patch release of fluka2008.3(d) in order to fix a couple of recent problems (a memory corruption in radioactive decay calculations, and the bounding box issue for ARB’s)??  Issue a pre-release before the FLUKA advanced course (October)???  Try to finalize a “real” public release before the advance course?? … discussion …

Sala INFN/Milan Paola.Sala@mi.infn.it Vasilis Vlachoudis CERN/EN Vasilis.Vlachoudis@cern.ch Two FSC members (chosen internally according to the field of interest) will give a quick look at the relevant presentation/publication and in case suggest changes/corrections. The election for the 5 non ex-officio members will be performed now, according to the procedure agreed (5 “points” available for each collaboration member to be used in whichever combination, 1 by 1 for 5 candidates, 5 on the same candidate, etc) Please whoever is willing to stand for election (including expiring members) contact me as soon as possible!!!
