The instrument is equipped with an automatic sample changer for up to 48 samples, housed in a vacuum chamber (<0.2 mbar), and is compatible with both 9.7 mm discs and 11.65 mm cups. Optical stimulation is provided by 870 nm infrared LEDs (>135 mW/cm²) and 470 nm blue LEDs (>80 mW/cm²). The internal irradiation system incorporates a 1.48 GBq (40 mCi) 90Sr/90Y beta source. Programmable heating is achieved with a Kanthal resistance heater, allowing temperatures of up to 700 °C for TL measurements, preheating, and isothermal treatments. Luminescence detection is performed using an EMI 9235QB15 photomultiplier tube, featuring a low dark-count rate and a linear response up to 40 × 10⁶ counts/s, combined with Hoya U-340, Schott BG-39, and Schott BG-3 optical filters. The system also includes a single-grain analysis module employing a 532 nm green laser and sample discs containing 100 individual grain positions.
This system is similar to reader 1, although lacking the single-grain analysis module. It can also be equipped with a violet stimulation system based on a 405 nm, 100 mW laser. This configuration employs ITOS GG395 (3 mm) stimulation filters and an AHF F49-402 ET bandpass 402/15 nm filter, while luminescence detection is performed through a Semrock BrightLine FF01-340/26 emission filter, enabling advanced violet-stimulated luminescence measurements.
This instrument is equipped with the automated modular DASH (Detection and Stimulation Head) system, which integrates optical stimulation, filter-changing, and detector-changing units. Optical stimulation is provided by seven LED modules, with a standard configuration comprising two blue modules (470 nm, ~80 mW/cm²), two green modules (525 nm, ~40 mW/cm²), and three infrared modules (850 nm, ~300 mW/cm²). Luminescence detection is performed using an Electron Tube PDM 9107Q-AP-TTL-03 photomultiplier tube, featuring a spectral response range of 160–630 nm. The filter changer consists of a dual-layer filter wheel equipped with Hoya U-340 filters (5 mm and 2.5 mm), Schott BG-39 (2 mm), and Schott BG-3 (3 mm) optical filters, providing flexible detection configurations for a wide range of luminescence applications.
The instrument is equipped with an automatic sample changer with a capacity of up to 40 samples mounted on 10 mm discs. Heating is provided by a metallized ceramic heater with programmable heating rates ranging from 0.1 to 20 °C/s, allowing temperatures of up to 710 °C under an inert nitrogen atmosphere. Optical stimulation can be performed using either blue LEDs (458 nm) or infrared LEDs (850 nm). The detection system employs a UV–VIS photomultiplier tube as the standard configuration, combined with Hoya U-340, Schott BG-39, and Schott BG-3 optical filters.
The Canberra Industries/Mirion GX5521 is a high-resolution gamma-ray spectrometry system equipped with a High-Purity Germanium (HPGe) detector. The detector provides a relative efficiency of 55% and an energy resolution of 2.1 keV. The system is housed within an ultra-low-background shielding assembly. This configuration enables the detection and quantification of low-activity radionuclides with high sensitivity and precision.
