SUMMARY

The discussion focuses on the integration of an ion trap with 0.3 mm rod radius and 1-2 mm length into a microwave cavity operating at 100 GHz. Key concerns include the reduction in finesse of the cavity due to the presence of the rods, which can significantly impact performance. Estimating this drop in finesse requires careful consideration of the geometry and material properties of the rods in relation to the cavity dimensions, which should be 3-10 times the wavelength. Additional factors to explore include electromagnetic field distribution and thermal effects on ion trapping.

PREREQUISITES
  • Understanding of microwave cavity design principles
  • Knowledge of ion trap physics and operation
  • Familiarity with finesse calculations in optical systems

I am thinking of placing an ion trap (0.3 mm rods radius, 0.6 mm from the axis and 1-2 mm long) inside a MW cavity at 100 GHz (assume the length of the cavity is 3-10 times the wavelength). What are some issues I need to consider while designing this? One main one is the drop in finesse of the cavity when placing the rods there. How can I estimate this? Also, what else should I look into? Thank you!
