Foreword
GB/T 4833 "Multi-channel analyzer" is divided into three parts.
--- Part 1. Technical requirements and test methods;
--- Part 2. Test methods as a multi-channel scaler fixed;
--- Part 3. nuclear spectroscopy histogram data interchange format.
This part of GB/T 4833 Part 2.
This section proposed by the Defense Science, Technology and Industry Committee.
This part of the jurisdiction of the Institute of Nuclear Industry Standardization.
This part mainly drafted by. Institute of Nuclear Industry Standardization, Shenzhen Academy of Metrology and Quality Inspection.
The main drafters of this section. Xiongzheng Long, LI Ming Zhao, Xiao Chen.
Introduction
Multi-channel analyzer (MCA) pulse count and data storage capabilities, some MCA can achieve multiple scaling function. In this case, more
Each channel analyzer memory quite a single channel scaler, and the entire MCA constitute a multi-scaler (MCS). You can preset time between press
MCS compartment in each track count, the time interval is determined by its internal or external clock. Meanwhile, MCS also retained the multi-channel analyzer
Data display, data processing and data output.
MCS is mainly used for measuring the decay curves and Mossbauer effect of short-lived radionuclides.
Multi-channel analyzer
Part 2. Test methods as a multi-channel scaler set
1 Scope
This section provides multi-channel analyzer measurement method as a multi-channel scaler (MCS) when the main parameters, and defines the characteristics and MCS
Related terms.
This section applies to multi-channel scaling function of multi-channel analyzer.

3 Terms and Definitions
GB/T 4833.1 and GB/T 4960.6 regulations and the following terms and definitions apply to this section.
3.1
When the multi-channel analyzer as a multi-channel scaler, 1,2,4,8 entire memory can be divided into two partitions, each according to Shun Road
Work order. Memory partition selection should give way to divide memory partitioning, each partition available channel number and the selected partition number.
3.2
And promote the MCS channel stepping clock pulses corresponding to the period of time interval, namely to stay in the count every time.
3.3
Because MCS per channel memory write address step conversion and lost track of time. Net count every time is the residence time
3.4
Added to the MCS "count" logic pulse input. With any logic pulses fed to the MCS, as shall be specified at the input pulse
Said features.
a) polarity;
b) logic level;
c) width;
d) rise time and fall time;
