Project Title:
Efficient Backward Wave Oscillators
for Millimeter and Submillimeter Wave
Applications
Technical Abstract (Limit 200 words)
This research will result in development of
advanced millimeter and submillimeter wave
Backward Wave Oscillators (BWOs). Successful
development will result in devices requiring
significantly less input power, require less cooling,
have reduced weight, and have improved mode
purity. Calabazas Creek Research, Inc. is
proposing to develop the first BWOs with a
depressed collector, spent-beam, energy recovery
system that will significantly reduce the prime
power requirement and allow air cooling instead of
water cooling. An additional goal will be to develop
mode converters between the slow wave structure
and the overmoded output to allow for single mode
operation. Finally, advanced permanent magnet
technology will be applied to reduce magnet and
system weight.
BWO sources are presently used for ground based
atmospheric sensing of trace chemicals, testing of
solid state sensors, and basic spectroscopy
research. This innovatve development will allow
these devices to be used for airbourne or space
atmospheric sensing missions, as well as reduce the
cost and complexity of BWO sources, making their
unique tunability and output power capability more
accessible to both private and government
laboratories.
Potential Commercial Applications (Limit 200 words)
The proposed program will result in the
development of efficient, lighter-weight, millimeter
and submillimeter BWOs applicable to the following
commercial applications:
* Laboratory and remote spectroscopy, material
analysis, aquametry, and medical research,
* Millimeter and submillimeter wave sources
available for airbourne and space missions for
molecular line astronomy and atmospheric
environmental sensing,
* Heterodyne sources for the new, proposed, large
array, radiotelescope system.
