CDF Plug Upgrade (tile-fiber) EM Calorimeter performed resolution
of 15%/sqrt E \oplus 0.7% with non-linearity less than 1% in a energy range of
5-180 GeV at Fermilab Test Beam. Transverse uniformity of inside-tower-response
of the EM Calorimeter was 2.2% with 56 GeV positron, which was reduced to 1.0%
with response map correction.  We observed 300 photo electron/GeV in the EM
Calorimeter.  Ratios of EM Calorimeter response to positron beam to that to
^137C_s Source was stable within 1% in the period of 8 months.
