  1. Preliminary results of the CAKE experiment S. Cecchini, G. Giacomelli Physics Dept. , INAS and INFN Sez. Bologna, Italy Russian-Italian Cooperation Workshop on CR and Astroparticle Physics Moscow, Oct 17-20, 2005

  2. CR Sources ? FIP Vol 1 part/m2h 1 part/m2 day High statistics: large collecting area + long exposure High charge resolution

  3. The CAKE experiment : A~ 2 m2sr for Fe nuclei CAKE is a prototype for demonstrating the feasibility of the full analysis chain

  4. ~1500 km 38 km plafond altitude Residual atmosphere 3.2g/cm2 Flight duration 18h

  5. Top layer Middle Bottom Relativistic charged particle Low-energy stopping particle Alignment reference holes Tracking algorithm

  6. preliminary old Charge spectrum of 1409 events from the measurements of 15% area Data(black dots)with statistical errors are compared to a MonteCarlo Simulation (histogram)

  7. Preliminary - 2051 events

  8. LDB 15-40 days 3 months • Recovery • Large area • Long exposure
