TED (Total Energy Detector)

[1] Summary of the Prototype Tests

• There are many phenomenon which we can not understand using the primary beams: saturation effect, pulse shape etc.
• We have studied the isotope separation for rigidity-separated (Δp/p~0.1%) secondary beams at 270 MeV/A. Combined with the energy degrader in front of TED, isotopes around mass 70 region could be separated with ~6σ separation.
  • 
• The reaction loss in the degrader and the CsI crystal is estimated to be about 15%.
