Accelerator Definition and 215 Threads

Particle accelerators use the electromagnetic field to accelerate charged particles. Would it be possible to build a particle accelerator for uncharged particles? Say we are given a narrow beam of neutrons. How could we accelerate them so that the accelerated particles were still in a...

I came across this and i was fascinated, i hopefully would like to attempt to build a recreation of this but i have no idra what they used to make the accelerator work on this size. Any help...

Hi folks, I have just found a video on youtube that shows how a 2 mile linear accelerator was built in 1967, I share it with you, hopefully you will enjoy it as much as I did:

Good Evening Everyone, A group of friends and I were having a mini-contest, to see who could theoretically make anti-matter using the most simplistic design in terms of cost and general complexity. The obvious choice for us was the Positron, due to low energy requirements on all fronts. One of...

Cool article I thought I'd share http://www.newswise.com/articles/the-hottest-job-in-physics

I wish build or buy an used particle accelerator in my garage or basement, 10MeV capacity is enough. Is that legal? Many counties no regulation on this matter, I guess.

Just wondering why to use negative hydrogen H- ion in spallation neutron source. I read the literature through http://neutrons2.ornl.gov/facilities/SNS/works.shtml , still not yet get the answer. If directly use proton, then still easy to accelerate, and no need to strip off the unwanted...

In linear accelerators that use a disk loaded structure (traveling wave), how would you calculate the iris(disk hole) radius, cavity radius, and disk thickness according to the wavelength

Homework Statement The device has two parallel plates, one positively charged and one negatively. The positive plate has a hole to allow electrons to fire out of it. b) How can the device be modified to accelerate protons? c) How does the escape velocity of a proton compare to that of an...

I do think that the idea I had recently and one that I have been pondering about since is something mundane. Specifically because its so simple. Yet its an abstract one that I would like to know more about it from someone who can take the time to think about it and write a paragraph or two. In...

I have a qustion about two types of accelerating designs. In these types of design the plates get longer or spaced apart because the frequency of the RF power is constant but the particle is acclerated so it covers more distance in less time. The other type of design looks like this: My...

Homework Statement You want to construct a simple particle accelerator and hit on the following design: you will take two oppositely charged plates with small holes drilled into them and set them up parallel to each other. You will create a vacuum between the two plates and fire a beam of...

From what I can recall the shape of tracks of particle accelerator is circular. Is it possible to change this circular shape in future particle acclerators, to shapes like some knots (with more than one crossing)? to gain more distance in less space, I don't know how construct it, but it's a...

Hello, I have just graduated from university with a decent (but not outstanding) result: 2:1, not far off of a first, with good references. I did my final year project on accelerator physics and I am currently working at the same university over the summer doing similar work on an accelerator...

Greetings I am not a physicist myself, so please forgive me, if my question/proposition will sound naif. I noticed some articles about accelerating electrons using laser and glass gratings: http://phys.org/news/2013-09-chip.html http://phys.org/news/2013-10-particles-compact-particle.html I...

Today is an exciting day, for today will see a new record for the highest energy collisions at the LHC - stable 13 TeV collisions for new physics, signalling the start of the new physics program at the LHC! There are a few ways you can keep track of progress throughout the day. The LHC status...

large facilities like CERN have multiple rings of different diameters to prep the beam for the main ring. I get this is something like gears in a truck. my question is what are the broad design constraints for choosing a specific number of rings of a specific diameter?

As I'm looking for summer research opportunities and internships, I noticed that the physics department at my university offers summer jobs to students (I'm guessing physics students) at our accelerator center (which focuses I believe mainly on ion beam analysis). Now, I'm an EE major. I plan...

This is 2 questions in 1 go. So my first question is how much does a Proton weigh? My second question is, what is the mass of the Proton in a particle accelerator going nearly the speed of light. I know that as you speed something up its mass increases. Also could you show me how you came to...

I am a non physicist-scientist, but landed here searching the internet for this answer. Has it ever been done? Thank you for any answers.

My 12 year old son recently created a homemade particle accelerator, with help from his grandfather, for his upcoming science fair. Below is his description and youtube video link. Any insight would be helpful. "Hi, I just made this particle accelerator and I was confused on what I was...

Suppose we launch two ships and move them close to the Sun. They have solar collectors and can absorb a massive amount of energy thanks to their proximity to the Sun. The ships are connected by a 1000 meter long rod of titanium, and each ship's rocket is position opposite the other's, so that...

Okay you're going to have to forgive me but I'm new to all of this and I'm still getting a hang of this website(as well as having little or no education/experience in much of any physics beyond high school),but I was wondering if it would be possible to make a particle accelerator that used...

i am a mechanical engineer and am highly interested in physics. i want to do my final year project on particle accelerators. have someone done a similar project if so what sort of accelerator can an undergraduate student fabricate?

Hi all I'm new to this forum, there seem to be quite some knowledge here. I hope someone can help shed some light on this. I took this exam about a week ago and I had no idea on how to solve this question, and I haven't been able to figure this one out since. Homework Statement In a tandem...

How strong of a magnetic field do I need to get a 20kv @ 60ma beam around a 90° turn? / Do I need more information to find out?

Hello everyone, this is my first contribution in this forum, I'm aware that this question had been asked many times either in this forum or elsewhere and I have indeed read at least one thread with a similar topic, however, unfortunately, I have yet to find specific answers that nail the core...

Hallo everyone! I would like to make a small and simple particle accelerator that a) looks good and b) works. So if you could guys help me i would apriciate it alot! Thanks in advance. Christos Papanikolaou

Hi folks, I have a BSEE and am interested in pursuing a PhD focused on accelerator physics. I had originally planned for an EE PhD in RF/Microwave, but after reading ZapperZ's accelerator physics thread and doing a bit of reading, I find myself drawn in this direction. I've looked at some...

Hi PF, I've been looking to do a physics project for a while, and I thought about trying to build a particle accelerator at home. I know there's a lot of potential risks involved, and I imagine some legal issues, but is it plausible for a 15 year old to build a crude particle accelerator at...

Homework Statement An electron (e=1.6x10^(-19) Coulomb) of total energy 10.22 MeV (\gamma about 20) is undergoing linear acceleration due to application of a uniform electric field of strenght E_0=1000 MV/m a)how large is the applied force, in Newton? b) Calculate the instantaneous radiated...

Hello! In next year I'm going to be a freshman on Czech Technical University (well, maybe, it is not final decision). My dream was always to "make that accelerators". Now, I'm stuck. So, what is the best Bc. degree for prospective Accelerator Physicist? 1. Experimental Particle and Nuclear...

As is in the title, I am looking for a better way to measure the velocity of a ball bearing (actually only looking for speed) that has been accelerated by a magnetic. If you don't know what a Magnetic Linear Accelerator is, then this link/video should help: I already have some success...

I always hear that when protons slam together, they annihilate into pure energy. Then that energy sometimes reforms into other particles. How does that make any sense? Energy is just an arbitrary mathematical quantity.

I have no idea if this is the right place for this topic. Recently, I have been reading about particle accelerator operation and theory. I had never realized exactly how the particles were accelerated. Turns out the particles are are bunched together in clumps by an ac wave and accelerated...

Someone has built a tiny particle accelerator on a chip: http://www6.slac.stanford.edu/news/2013-09-27-accelerator-on-a-chip.aspx https://www.youtube.com/watch?v=V89qvy8whxY I'd like to know if this type of approach could be used to build an Accelerator Driven Reactor System, for a small...

Will a car continue to accelerate after the accelerator is removed? I know this doesn't seem to make sense, but everytime I let go of the accelerator, the pointer still shows an acceleration though the value is decreasing. I'm just confused about whether it's a decreasing acceleration or...

Wondering if anyone has developed a scaling heuristic for the relationship between size of accelerator and smallest size that can be probed with it. With so many data points, something ought to emerge, perhaps a modified power law. Adding a time axis could make a Moore's "law" projection for...

I am looking to making a particle accelerator but I don't understand how to make a vacuums. Wouldn't sucking out all the air make the pressure inside very extreme crushing the container? Also how would providing magnetism move them? Would you have to angle the magnets to "direct" the particle?

Hi, I am writing my (undergraduate) research thesis on accelerator/particle/neutrino physics. I'm planning on writing about the history of this field (HEP) and what such research has tried to accomplish. Currently, I'm looking for some books to read up on the history and such of HEP...

I'm trying to replicate the voltages coming from an accelerator pedal, to the ECM, on 6.0 L Diesel engine. I acquired the three separate voltages using an oscilloscope. I have access to two analog output channels on the dyno. Out of the three voltages two them follow each other by a...

Hi I could not figure out what is the reason of measuring current in accelerator and it shows which features of the beam? any help would be appreciated.

Hi guys , Suppose there is a circular accelerator has the same inner structure of a linear accelerator in terms of the rings of acceleration ... The angular frequency of accelerated particles is : ω = qB/m = 2πf , and this is also the supplied current frequency ... The question is ...

What roles do engineers play in the field of accelerator physics, specifically electrical engineers. I would imagine something to do with electromagnetism or microwave engineering but I have no idea. Does anyone else know what they do in the field? Thanks.

Hello, I know there was a thread about this article at some point but take a look at this: http://www.symmetrymagazine.org/article/april-2010/a-field-where-jobs-go-begging It claims that Accelerator Physics is a field where jobs go begging! Regardless of whether the jobs go begging or not...
