![]() SRF cavities typically have Q-factors of 10E10 and trapped flux at pinning centers reduces the maximum effective accelerating electric field used to drive charged particle bunches close to the speed of light.įlux pinning is thought to arise in some Type-II superconductors by small imperfections in the crystal, also called volume defects, that enable flux to penetrate the material. In that application, trapped flux poses an issue by increasing the remnant surface resistivity of the cavity, which has the effect of decreasing its effective quality factor or Q-factor, which is a measurement of a resonators efficiency. TRIUMFLab contributed to flux-pinning studies in Niobium crystal superconducting radio-frequency cavities used for particle acceleration. It is not a property of diamagnets or diamagnetism. Just like hair comes in individual strands, or in other words hair is 'quantized' or 'discrete', so is the flux trapped at the 'pinning centers' quantized in what are called 'magnetic vortices' - the quantization of pinned flux lines is a key property and distinguishing characteristic of Type-II superconductors (although technically can occur in Type-I superconductors if the material thickness is smaller than the London penetration depth, which is indeed very small - specifics for the physics nerds out there).įlux-pinning is entirely unique to superconductors and is also wholly distinct from the Meissner effect. The hair in this case is magnetic field lines and the gum is the Type-II superconductor. You can think of this like strands of hair being caught in gum - the gum is suspended in mid-air by adhering strongly to the hair as the hair passes through it. These are the popular images and videos of cryogenically-cooled discs floating above a magnet frequently seen online and in the pinned post on my profile. Levitation of superconducting materials is a phenomenon unique to what is called Type-II superconductors, and is an effect whereby magnetic field lines becomes 'trapped' as it passes through the material, providing the force needed to levitate. What is the physical phenomenon behind this and what does it mean? This video was just posted to the Chinese video-sharing site BiliBili and claims to be a highly pure synthesized sample of LK-99. □□ Let's keep the conversation going! □️□įirst video of LK-99 Full Levitation, aka flux-pinning So, let's cherish and celebrate these amazing creatures! □□ Remember to share your own experiences and stories about animals and their heightened senses using #animals #heightened #senses #detect #supernatural #changes #behave. □□□️ It's truly awe-inspiring to see how interconnected they are with nature! □□ ![]() ⚠️ There have even been documented cases of animals displaying peculiar behavior before earthquakes! □□ For instance, you might have heard stories of dogs barking excessively, cats hiding, or birds acting erratically right before a seismic event. ![]() □ It's heartwarming to witness how animals behave and communicate with each other! □□ They might show unusual behaviors as a group, which creates a sense of collective awareness. □□ These responses might appear predictive, but they're likely a result of their acute awareness and connection to the world around them. □ Animals truly are remarkable beings!
