SERIES 6LB™ Automatic Low Background Alpha/Beta Counting SystemRequest a quotation
- 2.25” Gas Flow Proportional Counter with 50 or 100 sample capacity
- Complete frontal access with no need to lift lead bricks to access the detector – changer slides away from lead castle
- Integrated touch screen interface
- USB Communication protocol
- Compatible with Apex-Alpha/Beta™ software V2.1 or higher
- Coated and bolted lead shield
- “Lock and Load” easily removable and pre-loadable sample stacks
- Gasless Anti-Coincidence cosmic Guard Detector
- Much lower gas consumption than legacy systems
- Integrated self-diagnostics and environmental monitoring for temperature, humidity and barometric pressure
- NFC/RFID Sample tagging
- Available barcode reader and sample camera
The Series 6LB counter uses the novel “system on slide” concept where the shield is fixed in place while the entire sample changer and detector smoothly slides out and away from it.
SPECIFICATIONS (Preliminary – subject to change)
* All specifications are based on measurements performed at a Mirion manufacturing facility with 5.7 cm detector with ultra-thin window, unless noted otherwise.
- Gross (alpha+beta): ≤ 1.0 cpm
- Alpha: ≤ 0.10 cpm
- Beta: ≤ 0.9 cpm
- 4π efficiency measured with a NIST traceable standard point source 5.08 x 0.3 cm planchet in 0.3 cm insert.
Alpha (210Po): ≥ 38%
Beta (90Sr/90Y): ≥ 45%
- Counting efficiency is dependent on operating voltage, source thickness and distance from detector. Backscattering of high energy emitters produces higher than expected efficiency.
- ≤ 1.0% 210Po alpha into beta channel with the system adjusted for a ≤0.1% spillover of 90Sr beta into the alpha channel.
- Alpha (210Po) – ≤ 2.5% slope/100 V: ≥ 800 V plateau
- Beta (90Sr) – ≤ 2.5% slope/100 V: ≥ 200 V plateau
Sample Count Rate:
- 500000 cpm with ≤ 1.5% deadtime loss
Counting Time Preset:
- Adjustable between 0.2 and 9999 minutes
Sample Changer Capacity:
- 50 or 100 samples - dependent on model
- Net weight less cart – standard system 324 kg.
- Net weight cart with casters 54 kg.
