For a coplanar waveguide resonator with 1 5 kω sheet resistance and a kinetic inductance fraction close to unity we measure a quality factor in the order of 700 000 at 20 mk.
													
																	Inductance of a aluminum sheet. 
									
	
		
	
																	Regarding current sheet inductance formulas for single layer coils one of the most widely known is the one by wheeler 2 which states after converting to metric units. 
																	For a coplanar waveguide resonator with 1 5 kω sheet resistance and a kinetic inductance fraction close to unity we measure a quality factor in the order of 700 000 at 20 mk. 
																	We can think of the self inductance of a conductor as the mutual inductance between two identical conductors which coincide with each other. 
																	Furthermore we observe a sheet resistance reduction by gentle heat treatment in air. 
															
													
									
	
		
	
																	L d 2 n 2 l 0 45d μh where d is the coil diameter in meters n the number of turns and l the coil length in meters. 
																	The self inductance of a conductor is a special case of the mutual inductance between two conductors. 
																	A wide variety of aluminum inductance options are available to you such as other.
