Was there ever a small hadron collider? And is the large hadron collider a device built to facilitate collisions between large hadrons or just a large device that facilitates collisions between hadrons of all sizes?

Why has nobody answered my question?


Are hadrons of various sizes? Or are various sizes of collider built to collide uniformly sized hadrons? Or is the large hadron collider a special machine built to facilitate the collisions between large hadrons, leaving small hadrons untouched for some reason?

Does anyone know?

Hadrons come in many different sizes as you put them. Most aren't stable though and/or are intermediate stages.

To actually answer your question it is a hadron collider that is larger than anything that has gone before in the sense of energies. More energetic the closer the approximation, in a crude sense, in time close to the start of the universe. So journalists' idea about it being a big bang machine is not entirely inaccurate.

It could have been named a lot of less plain names rather than a generalised name for what it is, a large hadron collider. Calling it the Higgs machine would be silly as the Higgs may not turn up, or if you're Stephen Hawking and want to stir up a bit of interest you could suggest it won't be the first thing observed.

Does Mutter have any opinions/knowledge on the naming convention of hadron colliders? That'd be hadron colliders of all types you understand. Large colliders of little hadrons, large colliders of large hadrons, small colliders of large hadrons etc. You get the idea.
 
Why does this always conjure up in my mind some sort of Sub atomic SMIDSY as the wrong particles collide?

Are the Hadrons the equivalent of a bus or black taxi and the Higgs bosons the equivalent of a cyclist?

Ah..................

Now the user name makes sense!

Should have linked that before!

Do you actually work with a Seimens unit?


I used to. All GE at the moment. I took the name of the scanner as my username quite some time ago (with the e changed for an a to distinguish!) and it stuck. Do you know something about MRI?
 
..............ish

I did my Masters in Medical Imaging, specialising in Nuclear Medicine, but also qualified in CT and MRI en route. I used to do both about twelve years ago.

At present I am in the process of designing a new PFI department with SPECT CT and am brushing up on my notes!

Let's hope that the radionuclide shortage sorts itself out soon or the SPECT/CT will just become a very expensive CT scanner...:laugh::hungry:

(Helium supplies aren't exactly overflowing at the moment either, especially now they will have to refill the LHC!)

Barstewards!

I wrote a worst case scenario report for the Trust on the basis of the British and European reports (Thankfully referenced) but so far we are recieving normal supplies!

I hope that it wasn't completely over reported as I will look foolish if there is no shortage.

I know our department had to cut back on some of the routune scans, but they could fill the places with iodine (not sure which isotope).

I think I am lucky where I work, we work quite closely with our neuro SPECT group and I sometimes do some image analysis for them. However, in the end I am working to replace it all. :biggrin: At this very moment I am working on a replacement for one particular type of PET scanning. Watch this space...:biggrin:

Did we just go waaaay off topic here?:biggrin:

I recall a story years ago that Hitler wanted to convert his Zeppelin's to Helium in the mid 30's, but the only major manufacturer of the gas was the US and they told him to take a hike - which is why they never saw active service in ww2 and which is why the Hindenberg went up so spectacularly.

I didn't know that. The problem at the moment is shortage of production. As far as I am aware we are currently eating into the stockpile that the US has. I'm not sure if there are any new plants being built. I hope there are, otherwise we will no longer have MRI scanners, LHCs or most importantly balloons, which you attach your name and address to, and release in the hope of getting a message from some far and distant land like Nigera :biggrin::biggrin: Actually come to think of it, I have plenty of messages from Nigera...:biggrin:

Where'd you read that Linford? There is and was plenty of helium about, and the knowledge to extract it fairly cheaply from natural sources was well within Germany's means even then. I imagine it was more the catastrophic reputation of hydrogen airships that did it for them - even in countries like the US with almost limitless supplies of the stuff.

They'd have been crap for bombing in WW2 for obvious reasons.


There certainly is an issue with the supply of helium. Of course we aren't going to run out tomorrow, but prices have certainly risen http://www.purchasing.com/article/CA6518723.html

As with many things it depends on the ability to 'refine' the product. That remains in short supply and therefore so does the helium.
