1 Introduction

The MiniMCA MCA166-USB is a battery powered high performance 4K Multi-Channel Analyzer/Multi-Channel Scaler module comparable in its performance with laboratory grade MCA. High voltage supply for detector and preamplifier power supply are integrated as well as an internal amplifier and pulse shaping network. Together with a small detector it forms a pocket-size gamma spectroscopy system and timer / counter, which is well suited to the demands of field measurements for international safeguards, environmental monitoring, nuclear waste treatment facilities, radioactive transport control and similar applications.

Furthermore, the MCA166-USB supports a vast number of different detectors and its 4k resolution is adequate to support high resolution gamma spectrometry with HPGe detectors.

The MiniMCA software allows to operate the device as a general purpose multi channel analyzer (SPEC, WinSPEC) and multi scaler analyzer (MCS, WinMCS). Additional user programs which support safeguards specific applications as U-235 enrichment verification, spectral radiation survey meter mode supporting active length determination are available. See chapter 3 for more information.

The device can also be operated with the ORTEC software (MAESTRO, GammaVision, ScintiVision etc.); contact ORTEC for details.

The firmware of the MCA166-USB (software of MCAs internal processor) is described in Appendix 3 and 4. Instructions how to change the firmware can be found in Appendix 5.
