  The principal energy loss mechanism in a Nambu-Goto cosmic string network
involves loop production and the subsequent gravitational-wave emission.
Recently, it has been shown that the loop oscillations produce repeated
gravitational-wave bursts emitted at cusps. The calculations are extended to
estimate the number of burst repeaters, including kink emissions and kink-kink
collisions. Our findings indicate that despite the potentially large number of
kinks, we anticipate observing a higher number of burst repeaters from cusps
for both LIGO-Virgo-KAGRA and the Laser Interferometer Space Antenna. We also
conduct calculations using the second main loop distribution model in the
current literature. We find that this model predicts a notably higher number of
repeaters, which provides a reason to include it in future data analysis. These
results offer insights into the potential observability of different loop
features for future detectors, such as the space-based laser interferometers
Taiji and TianQin.
