Nuclear Instrumentation Module

It provides a common footprint for electronic modules (amplifiers, ADCs, DACs, CFDs, etc.

[2] The NIM standard also specifies cabling, connectors, impedances and levels for logic signals.

Apart from the above-mentioned mechanical/physical and electrical specifications/restrictions, the individual is free to design their module in any way desired, thus allowing for new developments and improvements for efficiency or looks/aesthetics.

As a consequence, NIM-based ADC modules are nowadays uncommon in nuclear and particle physics.

NIM is still widely used for amplifiers, discriminators, nuclear pulse generators and other logic modules that do not require digital data communication but benefit from a backplane connector that is better suited for high-power use.
