To set performance goals for TPC in Pt resolution IP resolution Two-track separation
Use Jupiter with a cheated version of track-finder Track-fitting by Kalman filter Hybrid track-fitting with TPC+IT+VTX, with
• Energy loss• Multiple scattering

Geometry of MUD
Active layer (10cm-thick, not segmented)
Air : Default, Gas chamber reserved Scintillator : test version
Absorber (40cm-thick) Iron (as a return yoke)
Barrel : 4 layers Endcap : 5+2(inner) layers Alternately placed barrel and
endcap layer Octagonal shape in the phi
direction Z direction
X-Y direction

B-field mapping
“B-field direction and magnituderoughly followed Yamaoka-san’s results”
4. MUD response with CAL information
1. Observed muon signal by muon detector2. Muons passing through the CAL3. Pion leakage from CAL (punch through)
e+e-→Z→qq (2 jets) event check
Single beam () test
4. Number of muons produced in Jets or created inside of the CAL
Unfortunately, solenoid is set to air at Jupiter default.I checked the interaction length as only 7.10 (CAL)
Ignored the solenoid material in this study

Summary Since I am not a good person to make a
summary of summaries, I will quote one of the Miyamoto-san’s LCWS2005 slides
My thanks to all those who contributed to this group and gave very nice presentations!
