The Nuclear Instrumentation Module (NIM) standard defines mechanical and electrical specifications for electronics modules ud in experimental particle and
nuclear physics. The concept of modules in
electronic systems offers enormous
advantages in flexibility, interchange of instruments, reduced design effort, ea in
updating and maintaining the instruments.著名的诗

旧丝袜The NIM standard is the first (and perhaps
the simplest) such standard. First defined by
the U.S. Atomic Energy Commission's report TID-20893 in 1968-1969, NIM was most recently revid in 1990 (DOE/ER-0457T). It
provides a common footprint for electronic
modules (amplifiers, ADCs, DACs,discriminators, etc.), which plug into a larger chassis (NIM crate , or NIM bin ). The crate
木屋架must supply ±12 and ±24 Volts DC power to the modules via a backplane; the standard also specifies ±6V DC and 220V or 110V AC pins, but not all NIM bins provide them.
Mechanically, NIM modules must have a
minimum standard width of 1.35 inches (3.43 cm) and a height of 8.75 in (22.225
cm). They can, however, also be built in
multiples of this standard, that is, double-width, triple-width etc.[1]
The NIM standard also specifies cabling,
connectors, impedances and levels for logic signals. The fast logic standard (commonly known as NIM logic ) is a current bad logic, with negative true (at -16 mA into 50
ohms = -0.8 Volts); an ECL-bad logic is also specified.
Apart from the above mentioned mechanical/physical and electrical specifications/restrictions, the individual is free to design his module in any way desired, thus allowing for new developments and improvements for efficiency or looks/aesthetics.
NIM modules cannot communicate with each other through the crate backplane; this is a feature of later standards such as CAMAC and VMEbus. As a conquence, NIM bad ADC modules are nowadays uncommon in nuclear and particle physics. NIM is still widely ud for amplifiers,
discriminators, nuclear pul generators and other logic modules which do not require digital data communication but benefit from a backplane connector that is better suited for high power u.
