Summary on RUNJOB data (1)?
?95 of all data was analyzed. ?The spectra cover
the energy range 10
-1000 TeV for proton
5 - 100 TeV/n for helium
1 - 70 TeV/n for CNO
1 - 20 TeV/n for NeMgSi
0.5 - 8 TeV/n for
iron ?Proton spectrum doesnt show any tendency
of steeping in observed energy range. ?Helium
flux is lower (about half) than JACEE , SOKOL
ATIC, but consistent with MUBEE and Grigorov
data. ?Proton and helium spectra are nearly
parallel
18
Summary on RUNJOB data (2)?
CNO spectrum has no indication of enhancement in
gt 10TeV/n region. Iron spectrum is consistent
with other groups within statistical error
2-ry/1-ry ratio was shown in TeV/n
region. All particle spectrum and average mass
covers the energy range from 30 to
1000TeV/particle. All particle flux is lower
than other direct measurement, but seems to be
consistent with ATIC (Moscow04)? The Spectrum
shape is similar to other direct measurement
gt flattering before knee ? Average mass is
nearly constant in our observation region,
30-1000 TeV with ltln Agt 1.5 (helium)?

Conclusion
? EGRET data are not in harmony with C.R. data
1) Energy calibration ?
2) Subtraction of SNR ?
3) I.C. or Brems. Photons effective ?
3) Novel sources ?
? 100 GeV 100 TeV-? are quite important
