Product Overview

The HA-MCA-J is a standalone, single-channel digital MCA supporting up to 32K channels. It is compatible with a wide range of detectors, including HPGe, NaI(Tl), and LaBr₃. The system integrates multiple functional modules: automatic pole-zero cancellation, high-performance ADC, digital baseline restoration, and signal polarity adjustment. All parameters are fully configurable via the included PC software.

Features

• High Conversion Gain:​ Maximum ADC conversion gain of up to 32K channels.
• Gate/Delay Input:​ Integrated digital gate/delay ports for constructing digital anti-Compton and anti-cosmic shielding systems.
• Automated Calibration:​ Automatic pole-zero adjustment, baseline restoration, and system optimization.
• Dual-Polarity HV:​ Built-in programmable high-voltage supply: +500 V to +5000 V and -500 V to -5000 V.
• Versatile Connectivity:​ USB 2.0 and Ethernet (TCP/IP) interfaces for data acquisition and control.
• Automatic Stabilization:​ Embedded automatic peak stabilization (stabilizer) function.

• Low Maintenance:​ Dual-scintillator detectors are resistant to surface contamination and require no consumables, ensuring a long service life.
• Superior Anti-coincidence:​ Anti-coincidence shielding efficiency > 99.9%, drastically reducing background counts.
• Precision Control:​ High voltage and discriminator thresholds are software-programmable, ensuring high setting accuracy.
• Automated Decay Correction:​ Automatically corrects activity for working and certified reference sources based on half-life.
