AVATAR-HCT Digital MCA
Introduction
The AVATAR-HCT Digital MCA is a concentrated embodiment of the company's years of technical accumulation in the field of scintillation MCA. This MCA is a brand new upgraded generation product, integrating voltage divider circuit, preamplifier, programmable gain amplifier, digital shaping filter, temperature acquisition and necessary power supply units. For different application scenarios, AVATAR-HCT Digital MCA opens all parameter setting interfaces and can dynamically adjust during spectrum measurement.
This MCA integrates multiple signal processing algorithms internally, including high-performance pulse height analyzer for spectrum acquisition, waveform discriminator for particle identification. The high-speed USB communication also supports LIST mode and virtual oscilloscope. It is a fully functional product.
