EVENT of 20 JANUARY 2005INJECTION TIME of IONS, PROTONS and ELECTRONS Hamlet Martirosyan YERPHI / CRD
INJECTION TIME of FIRST REGISTRATED IONS • He, C, O, Mg, Fe • Collisionless Propagation , ΔT = L/c *1/β , T(Injection) = T(Registration)- ΔT
Ion PropagationCollisionless or diffusion? • ΔT ~ L2/D ~ L2/ V.λ • λ= λoR2-δT(Regist)=a.(Etotal/Z).R δ-3+T(Inject)
INJECTION TIME of IONS • Ions of All Energies the Given Type were Injected Simultaneously (Injection - Energy independence) • Z - dependence
Protons Injection Time • Shock Speed - ~700Km/s • Flare Coordinate - N12W58 • Mag. Field Line Nominal Length ~1.017au • Simultaneous registration of protons • tinject=tregist –Δt (Δt - Real Propagation Time) • Δt(E) ≥ 1.017au / Vp(E)
Neutron Monitors • NMRc GV GLE Start • Oulu 0.8 6:51UT • Sanae 1.06 6:49UT • Yakutsk 1.7 6:50UT • Kiel 2.29 6:51UT • Moscow 2.46 6:51UT • Novosibir 2.91 6:53UT • Lomnicki 4 6:55UT • Hermanus 4.9 7:00UT • Jungfrau. 4.48 6:59UT • Bacsan 5.6 7:00UT • Alma Ata 6.61 7:03UT • Aragats 7.6 7:05UT

CONCLUSION IAREA of ACCELERATION • High Energy Protons (E > 100Mev) and Electrons(E > 20Kev) were accelerated and injected in the flare. Protons Injection 6:36 – 6:56UT Electrons Injection 6:33 – 6:43UT • All Ions were accelerated and injected on a shock wave . Ions Injection 6:48 – 7:10UT Flare Start 6:28UT CME Onset 6:33UT (N. Gopalswamy et al.)
CONCLUSION IIACCELERATION RATE • HIGH ENERGY PROTONS (E > 50Mev) TInject(E) = 3.05*E + 9.26 => dE/dT ~ Const >0 • HIGH ENERGY ELECTRONS (E > 20Kev) TInject(E) = 26.6*LnLn(E) – 29.475 => dE/dT ~ E*Ln(E),E=E0*exp(exp(ατ))
