We still have interest to TE01-TE02 window because of

• Low fields on the ceramic

• Wide passband

• Simplicity

§ But it requires TE10-TE01 Mode Converter

Good candidate is Choke Mode Converter

But it is better to decrease the choke volume to avoid additional parasitic resonance in window

New converter is based on the converters designed before( April, 1998, S.Kazakov, KEK ):

Not easy to make

Narrow passband
