CONCLUSIONS (1) CONCLUSIONS (1)

WE ACCUMULATED SO FAR WITH 8 FE CARDS 40k EVENTS

-- HIGH MULITPLICITY, SINGLE TRACKS (Summary by Marek and Marian)

BEAM TEST IS UNIQUE CHANCE TO COMPLETE THE TEST PROGRAM

February 12th , 2004Heidelberg TPC Meeting J.B.

CONCLUSIONS (2) CONCLUSIONS (2)

ONLY THE COMBINATION OF ALL FE CARDS WITH THE FINAL RCU (ALL FUNCTIONALITY) WILL ALLOW US :

-- TO PERFORM THE COMPLETE CALIBRATION PROGRAM

-- TO TEST THE FUNCTIONALITY UNDER “REALISTIC CONDITIONS”

February 12th , 2004Heidelberg TPC Meeting J.B.

CONCLUSIONS (3) CONCLUSIONS (3) (risk/performance) (risk/performance)THE FIELD CAGE AND GAS SYSTEM

ARE OLD !(RISK OF DAMAGE DURING TRANSPORT)

THE MATERIAL BUDGET OF THE FIELD CAGE IS NOT AS IN THE FINAL ALICE EXPERIMENT !

CONCLUSIONS (4) CONCLUSIONS (4) (MOUNTING OF FE CARDS)(MOUNTING OF FE CARDS)FINAL MOUNTING OF FE CARDS

CAN NOT BE TESTED DUE TO DIFFERENT SUPPORT STRUCTURE
