Scintillator tiles

Scintillator tiles

  • 3 mm Kuraray SCSN-61(25x25 cm2)

  • 3 mm Bicron BC-408 (25x25 cm2)

Machined with vacuum plate as holder

Whole Production starting now

P. Checchia ECFA-DESY St. Malo


Fib r es

Fibres

Room temperature curvature problem solved

Use middle temperature

(500-700) oven

Kuraray 1mm d.

Y11 300 ppm multicladding

> 3 ph e- /m.i.p./tile obtained stable in >30 days time

Si detector

Si Detector

  • Problems with the detector production:

  • 1)delay due to foundry, 2)bad quality in the first lot of wafers 3)second lot (4 wafers) under test:

Beam time at CERN:

Do you want to share it ?

Conclusions

Conclusions

  • Scintillator plates production starting

  • Si detectors to be tested (and final production to be scheduled)

  • Beam test with partial detector at CERN

  • Full detector test ( Frascati? ) by september
