There are 28 steps in electronics while the ultracold atomic cloud is prepared.

Inductance 40 mH, How the switch on time is different from switch off, why it moves during one process?

Measurement with a network analyzer:

Resonant freq. [kHz]	Capacitance [nF]	Li [mH]	Conditions
1510 MHz	0		Only the coil
718.25	0.47	3.9
520	1	3.25	102
371	2.2	3.1
173.75	10	3.27	103

$\omega_0 =1/\sqrt{L C_0}$

$L C_0 =1/\omega_0^2$

$L_i = (1/\omega_i^2-1/\omega_0^2)/C_i$
