Beam test results of Tile/fiber EM calorimeter
and Simulator construction status
2005/03/05 Detector meeting @KEKNiigata University ONO Hiroaki
contents1. Beam test results of EM CAL2. Full simulator construction work
2005/03/05 Detector Meeting @ KEK 2
Beam test of Tile/fiber calorimeter
• Requirements for Linear collider calorimeter– Fine longitudinal segmentation– Fine transverse granularity– Required resolution
1%E15%/σ/E: EM
We made a prototype of fine segmented EM calorimeter and tested at the pi2 beam line In March 2004.

Beam test module setupTile size : 4cmx4cmx1mm with WLS fiberSampling ratio : Pb/Scinti = 4/1(Hardware compensated)Number of layers : 6 super-layer (1 S.L. = 4 layers) 17.1 X0
Read out : 16 ch Multi Anode PMT with WLS fiber

Mega-tile structure and beam line
Mega-tile structure 1mm scintillator thickness 25 tiles (5x5) per layer and connected on each corner. Tiles are separated with white plastic str

Gain calibration scan• Use non-interacting particle
(MIPs) for the gain calibration
• Fit function : Landau-Like function• Fitting range : peak–3σ ~ peak+5σ
Relative error : ΔPH/PH ~ 2.0%

Precise measurement at fiber position
0.5 x 5 mm mesh scan at the tile boundary

No drops at the fiber position
Circle and square tilesare staggered in each super-layer
At the fiber position, scintillator thickness is only 0.2mm

Summary• Linearity : 2.0%• Energy resolution : • Position resolution
σx=5.4mm ± 0.3mm σy=4.5mm ± 0.3mm
• Energy dependence of position resolution
• Uniformity : 1.66%(RMS)• Response mapping
– No significant drop at fiber position– Good light containment inside of the fiber grove
