Gamma detector STTC

• Measurement of H*(10) ambient gamma dose equivalent rate • Energy compensated Geiger Mueller detector • Gamma dose rate measurement up to 10 Sv/h (1000 rem/h) • STTC-W Waterproof version for 25 m (82 ft) immersion The STTC probe is designed for gamma equivalent dose rate measurement. It can be connected to any CSP survey meter with the appropriate cable. For instruments already integrating a compensated Geiger Mueller detector, this probe extends the instrument measurement range and supports remote measurements up to 20 m (65 ft). The STTC instrument has a compact and robust metal case which includes the Geiger Mueller detector, the high-voltage power supply and the pulse shaping circuits. The STTC instrument uses the Time-to-Count algorithm from Mirion, enabling a unique range of measurement with only one Geiger Mueller detector. By using only one detector, the STTC unit offers a better angular response than any other probe with an equivalent measurement range. Additionally, the multiple detector switching effect is not an issue for the STTC probe. The STTC unit is part of the CANBERRA™ SMART Probe (CSP) family. It includes all key components of hardware circuitry (high voltage power supply, amplifier, discriminator, etc.) Also, the intelligence associated with controlling those components is located in the probe – that is control and storage of key parameters, settings, calibrations, probe ID, alarm settings (10 values for each unit to display with default setting), etc. Thus the probe is a fully- integrated subsystem communicating the measurement to the instrument.
