Exradin w1 main 1400

Exradin^® W1 Scintillator

Water equivalent detector

Exradin® W1 Scintillator Overview

Point dosimetry that's invisible to the beam

Has a k_Q of 1.000, making the W1 an ideal detector for SRS
Water equivalent
Inherently waterproof
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
