RX J1713-39 submitted for publication. Really nice peak ~14σ To be a lighthouse in southern hemisphere! (we can live as lighthouse-keepers). Molecular clouds EGRET source “beam dump experiment”

Multi-band spectrum SN1006evidence for electron acceleration! (Tanimori et al.) Samely electron? IC impossible! Other possibility? No! Proton acceleraton natural!!!!!!

Consideration on scale dependence! Might be a key to enigma of Cosmic-ray origin? RX J1713-39: peculiar SNR? can be explained by the same picture as SN1006. MKN421: something ? To extra-galactic cosmic-ray? More SNRs such as RCW86 and RXJ0852 (analysing) (observing) Other possibility ? SNR GC GALAXY extra galaxy NGC253 Coming soon

NGC253: a whole galaxy inside FOV (including halo) galactic cosmic-ray? high star burst rate

Contribution from Yamagata Univ. Development of electronics (Frontend Module)

Frontend Module For Cangaroo III

  • Speed-up

VME standard is employed.

  • Multi purpose

It issues signals to ADC, TDC, Trigger module, and etc.

Present status

29 modules has been fabricated and the test has been almost finished.
