Micro-Detective-HX Enhanced Capability, Ultra-Light, High-Fidelity Hand-Held Radioisotope Identifier AMETEK® ADVANCED MEASUREMENT TECHNOLOGY

Micro-Detective-HX • Wireless Remote Monitoring – Remotely control and monitor from a central location. • Portable – Light weight, long battery life, “one-hand” operation with GPS location. • Simple to Operate – Touchscreen or push button with audible and visual alarm indicators. • Rugged – High or low temperatures, water proof, dust proof and drop hardened. • Superior Algorithms – Low false alarm rates, more than 150 nuclide IDs and superior SNM search. • Gamma and Neutron Detection – Identification, dose rate and count rate. • Detects and Identifies x-rays and gamma rays from radioactive...

Micro-Detective-HX Hardware The Micro-Detective-HX features compact, light weight and rugged hardware. A 50 mm diameter HPGe crystal in a “hardened” cryostat is cooled by an integrated low-power Stirlingcycle cryocooler. The latest version Micro-Detective-HX features a new cooler, offering reduced levels of accoustic noise and vibration, and longer operation life. The hardened cryostat is entirely free of conventional molecular sieve, allowing the instrument to be turned off or on at any point in the detector cool down or warm up cycle without risk. This is impossible with conventional HPGe...

Micro-Detective-HX The Micro-Detective-HX in Use: Overview From the hardware standpoint the user interface comprises: • Two buttons on the front of the handle, Navigate (N) and Select (S), with which all survey and sampling operations can be performed. • A high-resolution, sunlight readable, color touchscreen provides an alternative way to choose menu options and enter data such as passwords and alarm limits. • Audio-visual feedback: Menus are designed to be operated with N and S buttons only, but if preferred, the touchscreen is always available. On-screen help messages display radiation...

The Micro-Detective-HX in Use: Modes of Operation How the -HX Collects and Analyzes Data • A flexible approach to minimize time and maximize effectiveness. • Continuous running and fixed time modes with “end survey summary.” • Maximum flexibility, maximum sensitivity. • Adaptable to the chosen CONOPS design. The -HX monitors for radiation at all times. It collects one spectrum per second, then begins analyzing a rolling window of the eight most recent 1-second spectra for radioisotope identification and alarms. • “Home” or “Passive Monitor” mode is the simplest form of operation. In this...

Modes of Operation: Long and Fixed Sample Modes During a Survey, in the Detect mode measurement, a source may have been located and closer scrutiny desired. Long or Fixed Sample modes may be used to achieve this. In Long Sample mode, a single spectrum is acquired for 30 or more seconds and analyzed once per second for alarms. Fixed Samples are treated similarly but have preset durations of 5, 10, 15, 20, 25, 30, 60, 120, or 300 seconds. In Long Sample mode, the live spectral display can be viewed. Long and Fixed Sample spectra and analyses are saved in the ICD1/ICD2 file pair for the...

The -HX and Digital Stabilization — Making the best of it Although a digital germanium spectrometer is a highly stable instrument, even with varying temperatures, the -HX is designed for use in conditions that could be considered extreme (which certainly are not recommended but, within the specified mechanical and environmental limits, are not a barrier to correct operation). An automatic gain stabilizer system “locks onto” the natural background K-40 peak (if present) to ensure “perfect” calibration is maintained even in conditions of harsh handling. The stabilizer is “smart.” If either...

Micro-Detective-HX Offline Analysis Program • Views the spectral contents of -HX data files, real time and live time for each spectrum contained in each, radioactive sources identified (if any), and alarm types associated with each identification. • Reanalyzes the data set with different nuclide libraries. • Exports all spectra in an -HX file to a set of ORTEC .CHN format spectrum files. The .CHN files can then be viewed and analyzed in more detail with ORTEC applications such as the GammaVision Gamma-Ray Spectrum Analysis and MCA Emulator. The Micro Detective-HX Offline Analysis Program is...

Micro-Detective-HX Technical Specifications Dose Rate Visual over range indication and continuous audible alarm, user settable. Over-ride alarm at dose rates >10,000 |jSv/hr. Internal HPGe Detector P-type high-purity germanium. Coaxial construction. Crystal Nominal Dimensions 50 mm diameter x 33 mm (±10%) length. Cryostat and Cooler “Hardened” cryostat, with high-reliability, low-power Stirling cooler. The cryostat design is such that the Micro-Detective-HX may be switched off at any time and power subsequently re-applied, without having to wait for a full thermal cycle (full warm up before...

Micro-Detective-HX Communication Software The Micro-Detective-HX is a member of the ORTEC CONNECTIONS family. Remote MCA control and individual spectrum download, even over a network, is achieved simply, by the use of the included MAESTRO-PRO Advanced Spectroscopy software. MAESTRO-Pro is an advanced spectroscopy application which includes support for multiple languages, extensive calibration features, N42 spectrum file support, peak fit and analysis results display, expanded automation functions, and more. Multiple spectra may be block-transferred from the instrument controller to external...
