Overview
The Auniontech Lightbright Miniature High-Power X-Ray Tube is an engineered solution for energy-dispersive X-ray fluorescence (EDXRF) and wavelength-dispersive X-ray fluorescence (WDXRF) systems requiring high photon flux, compact source-to-sample geometry, and stable long-term operation. Designed as an end-window transmission-type tube, Lightbright employs a thermally optimized architecture where the anode is directly bonded to a custom heat sink via a low-thermal-resistance interface—enabling continuous operation at up to 100 W without active water cooling. Its ability to sustain beam currents of up to 11 mA at excitation voltages as low as 3 kV delivers exceptional signal-to-noise ratio for light-element analysis (e.g., Na, Mg, Al, Si), significantly reducing measurement dwell time while maintaining spectral fidelity. The tube operates across a broad voltage range (4–50 kV), supporting flexible excitation strategies for multi-element quantification in compliance with ISO 22058, ASTM E1621, and IEC 62321-5.
Key Features
- Miniaturized form factor with integrated O-ring groove for seamless integration into vacuum or helium-purged XRF spectrometers
- Direct thermal coupling between anode and heat sink—eliminating intermediate thermal interfaces and maximizing heat dissipation efficiency
- Stable 7×24 h operation enabled by robust thermal management and precision-machined beryllium window (standard 50 µm thickness; optional 127 µm for enhanced durability)
- High-current capability: 11 mA at 3–50 kV, enabling rapid acquisition of high-statistics spectra for low-Z elements
- Modular electrical interface: Pre-integrated Mammoflex® HV and LV cables compatible with industry-standard high-voltage power supplies (e.g., Spellman, UltraVolt, Matsusada)
- Configurable target materials—including W, Rh, Pd, Ag—to optimize characteristic line intensity and background suppression per application
Sample Compatibility & Compliance
Lightbright supports solid, powder, thin-film, and liquid samples in both benchtop and OEM-integrated XRF platforms. Its short focal spot (1000 µm) and wide beam angle (75°) facilitate efficient coupling with polycapillary optics or large-area SDD detectors. The tube meets RoHS Directive 2011/65/EU for hazardous substances and complies with IEC 61010-1:2010 for electrical safety in laboratory equipment. All configurations are designed to support GLP/GMP workflows, with traceable calibration documentation available upon request. Vacuum compatibility (≤10⁻⁵ mbar) and helium purge readiness ensure minimal absorption loss for soft X-rays below 1 keV—critical for compliant testing under USP and EU Pharmacopoeia 2.4.20.
Software & Data Management
While Lightbright is a hardware component, its operational parameters integrate natively with standard XRF control software suites (e.g., Thermo Fisher OMNIX, Bruker ESPRIT, PANalytical SuperQ). Digital feedback signals—including real-time filament current, tube voltage, and emission current—are accessible via analog outputs (0–10 V) or RS-232/RS-485 interfaces for closed-loop stability monitoring. For regulated environments, audit-trail-capable data logging can be implemented using third-party SCADA systems compliant with FDA 21 CFR Part 11 when paired with validated acquisition firmware. Auniontech provides detailed pinout schematics, timing diagrams, and HV interlock specifications to support full system validation.
Applications
- Portable and benchtop EDXRF analyzers for mining, scrap metal sorting, and environmental soil screening
- OEM integration into automated production-line coating thickness gauges (e.g., Zn, Sn, Cr on steel)
- Research-grade micro-XRF mapping systems requiring high spatial resolution and low-Z sensitivity
- Quality control of lithium-ion battery cathode materials (Ni, Co, Mn, Fe quantification)
- Compliance testing for restricted substances in electronics (Pb, Cd, Hg, Cr⁶⁺, Br per IEC 62321)
- In-line cement clinker analysis for CaO/SiO₂/Al₂O₃/Fe₂O₃ ratio optimization
FAQ
What is the maximum rated power for Lightbright tubes?
Standard configuration: 50 W continuous. Custom 100 W version available with reinforced thermal interface and upgraded filament assembly.
Can Lightbright operate in vacuum or inert gas environments?
Yes. The integrated O-ring groove enables direct flange mounting to vacuum chambers or He-purged housings—no external sealing adapters required.
Is beryllium window replacement supported in the field?
Window replacement requires factory recalibration and high-vacuum bake-out. Auniontech offers certified refurbishment services with full performance revalidation.
Which target material is recommended for light-element analysis (Na–Cl)?
Rhodium (Rh) is preferred for balanced intensity and low Bremsstrahlung background; silver (Ag) may be selected for higher sensitivity to sulfur and chlorine.
What is the typical lead time for delivery?
Standard 50 W units ship within six weeks from order confirmation. 100 W and custom-target variants require additional qualification and typically ship within eight weeks.
