Exradin® W1 Scintillator

Exradin® W1 Scintillator Overview

Point dosimetry that's invisible to the beam

  • Has a kQ of 1.000, making the W1 an ideal detector for SRS
  • Water equivalent
  • Energy independent
  • Temperature independent
  • Pair the W1 with the SuperMAX Electrometer to effectively eliminate Čerenkov effect without the need for extraneous calculations.
  • The W1 can be connected to any dual channel electrometer
