The scope employs a [[micro-channel plate]] CRT design to get good screen intensity at high sweep speeds with moderate acceleration voltage.

Many R7103s were used in nuclear instrumentation, i.a. because
<blockquote>
''[...] Waveforms as fast as 1 ns per division can now be recorded on high-quality films substantially resistant to unwanted radiation exposure.''
''[... The MCP] provides a gain in waveform brightness of several thousands. This level of brightness allows for a selection of film-processing combinations that are highly resistant to unwanted radiation.''<ref>https://www.osti.gov/servlets/purl/6731423 ''Oscilloscope Photography at Nevada Test Site (1990)''</ref>

==Mighty Oak Nuclear Test Incident==
{{Custom ICs|R7103}}
 
<blockquote>
''"MIGHTY OAK was conducted on April 10, 1986, below the surface of Rainier Mesa in the T-tunnel complex. Containment of MIGHTY OAK was satisfactory in that there was no accidental release of radioactivity to the atmosphere whatsoever. However, the tunnel grout in the near-cavity region was not sufficiently constrained. Failure of this plug led to the subsequent failure of the mechanical closure systems and to the eventual flow of cavity gas, plug material, and other debris down the line-of-sight (LOS) pipe to the experiment chamber and the tunnel complex beyond."''
<ref>https://www.osti.gov/servlets/purl/5363382 ''Mighty Oak Containment Review'' (1989)</ref>
</blockquote>
 
The Mighty Oak containment failure in the tunnel reportedly destroyed 100+ oscilloscopes.
 
<blockquote>
''"All of the diagnostic equipment, and much of the construction equipment in the tunnel complex were lost as a result of heat damage and radiation contamination. At present, the loss of normally recoverable and reusable equipment is reported at approximately 32 million dollars."''<ref>https://www.osti.gov/servlets/purl/6607938 ''Containment and Safety Review for the  Mighty Oak Nuclear Weapon Effects Test'' (1987)</ref>
</blockquote>
($32M in 1986 is almost $90M in 2023 dollars.)
