Dimensions and electrical parameters of resonators

	SLSG LGR	AGR
Inner diameter	19 mm	23 mm
Outer diameter	21 mm	25.4 mm
Length	15 mm	22 mm active region 40 mm with end rings
I-shaped conductor central part	-	12 mm
Fraction of volume occupied by sample*	0.82	0.46
L	21 nH**	19 nH***
C	10pF	4C = 87.63pF***
C'	N/A	3 pF
R	2.9 kΩ	1 kΩ
λ	0.3G/√W (Q=36)****	0.12G/√W (Q=11)*

^*fraction is calculated as a ratio of the sample volume of AG/LGR to the volume with strong B₁ in a resonator;

^**measured parameter;

^***calculated parameter;

^****measured in assembled AG/LGR, while AGR was terminated by 50 Ω load
