Components of TOF Sub-Assembly

• 120 - scintillators per segment.

  • BC404, 200mmx8mmx8mm

• Hamamatsu R5900-M4 PMT

  • Segmented 2x2 multi-anode.
  • Excellent performance.
  • Cost effective.

• Light Guides

  • Match 1x4 geometry of scintillators to the 2x2 geometry of the PMT anode.

• Mounting Fixture

  • Align light guides to PMT.
  • Support the component.

• Magnetic shields

  • Reduce attenuation in PMT due to magnetic field.
