EXCERPT:


8. 0 SUMMARY AND CONCLUSIONS 2
Portable cesium beam clocks (model 5061A) cannot be expected to
perform as well under traveling conditions as they do in the laboratory.
Our results show that quasipermanent rate changes as large as 5 nsec/hr
(120 nsec/day) may occur during trips with clocks that have shown
considerably
better performance in the laboratory. Of course, such changes
reduce the utility of these clocks. For example, if a flying clock
changes
rate by 5 nsec/hr shortly after the beginning of a two-week trip, and no
other significant changes occur, synchronizations with this clock
shortly
before the end of the trip would be off by 1. 6p sec. However, our
results
also suggest that the average of four flying clocks permits
synchronization
with an uncertainty of less than 1 nsec/hr (24 nsec/day), assuming no
intercomparison data are recorded. With intercomparison data, it should
be
possible to reduce the uncertainty even further.

Although the final analysis of our data is not yet completed, we
have established, with an intermediate level of analysis, that portable
cesium beam clocks are capable of showing relativistic effects with
relatively
inexpensive commercial jet flights. The results of this analysis are
in reasonable agreement with theoretical predictions. However, those who
doubt the validity of conventional relativity theory, and there are many
people in this category, probably will not be converted by the results
shown
in Figure 4. Indeed, the difference between theory and measurement in
Figure 4 is disturbing, and if our final analysis does not improve
agreement,
an improved version of this experiment should be given serious
consideration.
The standard deviation on the measurement could be reduced considerably,
probably
by a factor of ten, with such improvements as the use of dual beam
clocks and
circumnavigations with less ground time.
