JIM, Mike, Today discussed on Scientific Sense
Mike. Yesterday's James falls of physics estimates. Today he's also co director of the center for flights and superconducting technologies at question. Jim thank you for having. Yeah thanks for doing there. So i have to want you jim before you start I was not in the mid eighty s. And it's getting school out but since then i've lost most of engineering so i ask you some basic questions on all topics today Then so i want to start with a. It's a get bill de superconductors. Make better quality celebrators and so this is from last year you say be. She'll impurities can increase the maximum accelerated field of superconducting radio frequency. Cavities in finding the huge potential savings now. So superconductors are are these things that can connect custody but regardless nova systems but what superconducting radio frequency cavities their their superconductors in the shape of a cavalier. So there you actually pull off the air or the interior of the doctor Think of it is not something elipsoid and the typical sizes will be on the order of of a a meter to half meter and some smaller material is used furby land for building suburban radio radiofrequency. Check these we call him as our f kennedy's for short Is a is a matured as a mill. Ob his niobium each elemental superconductor is It's easy to relatively easily manufacturer. She'd serve This how and shape it into geometry's you want and there's a lot of engineering that goes into designing the shape of these categories. Warn the purpose of supporting electromagnetic reaper waves inside of the cabin. And so so so you get super conduct acting phenomenon all the in the cavity superconductivity on x to So let me just say the. The the purpose of these care is is You string together. And if you put charged particles view inject charged particles electrons and protons into the cavity. The electric field of magnetic wave in the cavity can accelerate the judge portal's through the county. And what you do. Is you string many of these. These these kennedy's together. And you coordinate the direction of the electric field. That provides a force in george markle's such that they drove from cavity to county get an additional kick additional force that way you're allowed to you're able to accelerate the charged particles through through the cabinet that makes up the exhort for example the territory on harvey bar the a the r these accelerator large hadron collider in geneva the superconductor its purpose is the the it is to shield to prevent the electromagnetic field from escaping the walls of the cavity and superconductivity is is the is the physics behind find the field inside the vacuum of the solar and so the large hadron collider really big machine but he expensive so so this idea would this help I know that has been some The might years on desktop accelerators. So could you make you know. We swore versions of a particle accelerator using this in the firm nationally. Silla reiter led the design of charities accelerators for many different purposes beyond just doing fundamental physics at very large facilities like like the alleged cer the temperature on slack so their commercial uses for long used as technology for for medical studies to charged particles or radiation to mitigate tissues in some cases are there's a lot of uses for celebrators. These allow us sort of the veterans that have been conducted at a. Let's see Off that has been planned or this would be in a different commission collection. Llc in future direction for next generation for looks over from physics brisket up not down. It's a matter of Of of just how much you can accelerate particles and get them up to high enough energy so that you can explore regions of physics that haven't been explored before so the next generation round up breathe or the next generation of of the international collider will will be larger scale or on a different design in a circular than than a circular accelerators. Such as alex. See the japanese. Government is considering building a high-powered linear accelerator. Future and the firm labs will be involved in designing the cavities for that accelerate. So the union accelerators rather than the the one that be having geneva though. So how how big Watch the length of that year actually to that's being planned. Oh yeah so. I'm not the expert on the on the japanese machine but the ones lack is on. Order of cloners won't okay. So so this technology you see here that The call impurities increase the maximum excavating field. So this is this is sort of new right. So you mentioned the opium as sort of the substrate. That's being used so so. What's.
