This page explains connectors commonly used in the nuclear industry and why you'd want to use one vs the other.
Early equipment (ie NIM bins) primarily use BNC. Later equipment still uses BNC but some equipment (notably CAMAC) uses Lemo 00 connectors. Lemo connectors are much more expensive than BNC but are more compact and should provide a snugger fit.
Nuclear Instrumentation Model (NIM) backplanes primarily focus on analog signals. The crate (chassis + power supply) provides some interconnect but primarily provides power and cooling. Instead, signasl are primarily patched through BNC connectors on the front of the module.
NIM's can use either TTL or ECL logic. My understanding is that generally TTL is less expensive but ECL is faster.
CAMAC focuses on digital electronics and computer control. It introduces a communications bus with a bus controller in the rightmost slot. The bus controller can be a standalone unit or provide PC connectivity through GPIB, RS-232, etc.
CAMAC primarily uses LEMO 00 connectors with occasional BNCs.

JM general reccomendations:
Most common type I see. Three pin is most common, but also seen more (ex: on SEM). Retention / clamping ring style also seems to vary.
Sample equipment using this:
Primarily used on Ludlum detectors/meters.
Notes from 2015-12
Found connectors under the following names. I haven't looked to formally figure out the differences
