Preliminary results of the multipacting measurements in Bd.181

Principle

Measurement at 187.73 MHz60 s power sweep from -25 dBm to -5 dBm

Measurement at 223.38 MHz60 s power sweep from -40 dBm to 0 dBm

Measurement at 130.48 MHz60 s power sweep from -25 dBm to -10 dBm

variable magnetic fields

Summary

• All recent results basically are the same like the results of former experiments

• No change of behavior at different frequencies so far

• Magnetic field has a huge impact on multipacting which also could be seen in former experiments
