This shows my character in front of the Compact Muon Solenoid at the Large Hadron Collider and is my way to celebrate a decade working in the collaboration.
This is a commission by
Honovy for rakan, where I provided the background for this picture and Honovy drew the character into it and adapted the background to the overall style of the picture.

To be honest, instead of listening to what he says I'd probably just be gazing at him. I mean come on, a fine specimen like him deserves to be admired from time to time. Besides I wouldn't be able to understand a single word of his explanations even if I cared to pay attention.
Wonderful picture again. Very nice job on the background. Looks fantastic.

I honestly think we need more "slice of life" furry art - I absolutely love this picture for example: https://www.furaffinity.net/view/18462769/
Hehe, I actually had to look up the case if there is no Hawking radiation since I was not sure about that case :D
If Hawking radiation exists, that would leave a very visible signature in the detector. However even if no Hawking radiation would exist, the presence of a black hole would leave a measurable signature in the detector.
HOWEVER: Since the production of black holes at the LHC energy scale requires extra dimensions in all likely models, I personally don't think we will see them at all (I actually dislike string theory for the same reason)...

There is a non-zero, infinitesimal chance that all atoms in your heart suddenly decide to tunnel 1m to your left, but I wouldn't worry about that
There are *MANY* arguments why it's safe - but here is just one that is easily understood (and without more knowledge about particle physics):
The earth is constantly bombarded by particles with much, much higher energies than what is available at the LHC - and in all the billions of years since the earth exists, nothing bad happened ...
So in the end we are repeating that same experiment at a much smaller scale - just with a nice detector all around that point of interaction so we can better measure what's happening.
(Although the whole field of astro particle physics still manages to measure interesting things about the interactions that are happening in our atmosphere using square kilometers of surface, cluttered with detectors in some remote places...)

its going to have to be a year when i help a friend move to norway
i have always wondered exactly how many of the detectors actually work, i have never had a satisfactory answer on any of them despite being on a team that in college designed several different amplifiers for this such an application

Well - each detector is slightly different but usually has 5 components from the innermost to outermost subsystem:
1) Tracker - that measures very precisely where charged particles pass through it
2) ECAL - this measures the energy of electrons and photons by completely absorbing them in an scintillating material (the absorbed energy is converted into light that can be measured very well - after being amplified a LOT). Heavy hadrons (like protons) deposit only some part of their energy there but manage to continue on their path
3) HCAL - this usually consists of lots of layers of absorber material with some scintillating material in between layers - this should be enough to absorb all the remaining energy of the hardrons that survived.
4) Big ass magnet - this curves the path of charged particles in the tracker (and muon system) to allow a momentum measurement
5) Muon system - this is a lower precision tracker ... The only particles that can pass all the previous detectors due to their properties are uncharged neutrinos and charged muons. The muon system tracks the position of the charged muons.
Finally by combining the momentum and energy information (and which detector "saw" something - and where) - each of the many many particles from the collision at the center can be identified (or a likely guess can be made).

i understand that much from from the final results, but i have never had it explained exactly how they are detecting these particles and how they track them threw space
how does one convert a fundamental particle to an electron and do so with such resolution in something that happens so fast
i understand basically only the amplifier/trigger section as thats what i worked on (near avalanche super-speed triggering FTW)

From the perspective of the detectors / electronics - the particle reactions can be seen as pretty much instantly happening...
For the tracking and measurement - it really depends on the subdetector...
The tracker just says - particle x crossed here - since it's split into really pieces (micrometer scale in some parts), the location is pinned down quite well. The muon chamber gives the same information - but with a much larger resolution (since it's further from the center that's not so bad).
The passing charged particle causes some charge separation in the material (gas or semiconductor) and the resulting current can be measured - after a lot of amplification. And if you have multiple layers with this hit information, you can calculate a path through these points (and whether it originated from the center or from a particle that decayed a bit further away). Considering there are 1000 particles flying away from the center - that's actually quite a feat :P
The calorimeter gives the information - particle x deposited energy Y ... and is split into much larger pieces (centimeter scale). The incoming particle causes a chain of particle reactions in the material (called shower) and the total sum of energy from the absorbed daughter particles is measured by measuring the very faint light that the material emits during this process with a very sensitive photodetector.
Not all measurements are fully complete within the few nanoseconds between the collisions - in particular in the calorimeter, where it's not just "seen vs not seen" but it matters "how much light" was measured. In these cases, the electronics measures the progression of currents and you can disentangle the different events with a bit of analysis to find out how high the current was
In the end all this information is combined so we know it was very, very likely an electron, photon, pion.... or whatever :P
I hope this answer helps you :)
Cheers, Rakan

This is amazing in so many ways!
Firstly the fact that you had an art piece feature the LHC made me giggle! (I'm a nerd and physics is one of the branches of science that captivate me like no other, save for Computer Science) There's two places I would adore to visit in the world: CERN and the LHC, and Chernobyl. The LHC to see what the future holds, and Chernobyl because I'm not at all radiophobic and would love to go with my geiger counter and explore every inch, er... centimeter of it!
Secondly, why can't all physics professors be that hot... You want more kids going into STEM? Have more of that sexiness promoting it!

Hehe - thank you
It's a long way from Georgia - but there are always guided tours of the LHC going on... - and when the LHC is in shutdown you even get to visit the experimental caverns after a few weeks (when the lingering radiation is low enough). Next year the LHC will enter a long shutdown for upgrades - visiting during that time will probably be the best experience.
I'm torn about Chernobyl - I would like to visit to see it, but I'm actually a bit afraid of radioactive dust particles that might still be around and could be disturbed by something falling over while exploring.... Having some alpha source in your lungs is no fun ... In the LHC the situation is much different and waaay safer ...
While I do some lectures at the university, my position does not carry the title professor ...

Yeah, unfortunately it'd be a LONGGGG plain ride over there, but if I was gonna do it I'd definitely hit up both CERN/LHC and Chernobyl at the same time. I think it'd be amazing to tour the LHC complex, and just CERN in general! Unfortunately with my last year of my bachelors degree coming up, and then hopefully a Masters program after that, I doubt I'll be able to make it over there anytime soon. But hopefully I will one day!
Come now, you haven't lived if you don't get a little radioactive dirt on your paws! And there's nothing wrong with a little Alpha decay in your lungs! It gives you a good and hardy constitution! Besides, where else on Earth can you go to hold ACTUAL nuclear fuel in your hands! (I'm not actually joking. One of your fellow Deutsche physicist did just that in Chernobyl, more than once actually! Here's the video of it, cause nothing says fun like holding something putting off 115 mSv/h in your hand: https://www.youtube.com/watch?v=6kg4vVYKc90 )
Aww... Does this mean we can't call you Doctor-Professor Rakan? (I truly hope you know where that joke comes from!)

I've been to the states a few times - I know how annoying long plane rides can be :P
I wish you the best with your studies - only really started visiting other countries and started seeing more about the world after I finished my master (although I was in the US earlier to visit my brother while he did an internship there - I still very much remember my flight back ... on september 10th 2001 - *phew*).
Uhm - I prefer to live without radioactive dust in me ... one should not tempt the healing powers of a werewolf
About that video ... dirt with 115mSv/h is CRAZILY dangerous I'm ok with standing next to the radioactive LHC beam pipe when the RPO gives a green light - but a few minutes next to that easy to spread dirt would use up my yearly dose allowance ...
I'm actually a bit too old for spongebob - at least a quick google search gave me these hits for "Doctor-Professor" ... And while I have the german "PhD" title: "Dr. rer. nat." there are strict rules about the use of that title, so I can't use it together with a nickname like Rakan

Oh cool! Hopefully us 'Muricans treated you right!
Thanks man! I'm planning on going for an MBA in IT Management, so ya never know, our paths may cross someday in the future!
And dang, no wonder you remember that flight well...
Hey now, you gotta add some spice to life, and some radioactive dust, and a werewolf bite, will do that!
Lol! Yeah, I imagine 115mSv/h for you would cause some yearly exposure issues. I would be ok doing it, though only briefly, because the most radioactive things I have are a Radium pocket watch that put off 50k Counts Per minute and an orange Fiestaware plate that put off 40k CPM, both WAY lower than that nuke fuel fragment and I don't handle them on a daily basis! Yes, I collect things like that...
Lol, I sorta figured you might be too old for Spongebob, but at least you got the joke! I find it funny that the use of "Dr." is strict over there, as there'd be no issue over here with calling a character, "Doctor Wolf". Funny how different cultures handle stuff like that! America is very not-stuck up with stuff like that, which sorta fits our nations personality well!
*PS, sorry my reply before this didn't actually stay a reply. I typed it in reply to your first reply, but I guess it decided it should be a comment on it's own.*

Yeah - I've been to the west coast (from Seattle to SFA), east coast (DC&NYC and Pittsburgh) and Texas (Dallas) and I was always treated well
Oh - the rules don't apply to works of fiction. The wikipedia articles says about it in the english speaking countries in the 19th centrury: "However, the title, not being protected by law, was adopted by quacks." ... and that seems to be the reason that people don't use "Dr." all that much anymore and use MD, PhD etc instead - although it looks like it is nowadays protected the same way as it is here.
Anyway - It really isn't that important tbh. out of all the different ID / credit / whatever cards I have, only my healthcare card has it on it, since they somehow found out about it.
Yeah FA is sometimes weird when it comes to replies ... The same happened to me when I replied to you on the other submission...

Well, that's good to hear! I can't speak for those weird Northerners, but us Southerners should most definitely have treated you right!
That's really fascinating! Over here, unless there's something I don't know about, anyone with a PhD is called a "Doctor", whether medical, academic, or none-of-the-above! If I got a PhD in Business, I'd still be able to be called "Dr. Wolf", with no one blinking an eye. But that's because we put little emphasis on the title of someone, as it's used mainly as a badge of achievement, more than of a strict role persé! The same goes for a doctor that doesn't have a PhD. They would also be "Dr.", but they wouldn't have a PhD for it. Basically, titles before names mean very little here! (To be called by your first name here is generally common in things less than a purely professional setting! )

Oh - don't get me wrong ... The title isn't something that's used very often ... that something from the 1900s or something
Otherwise it's more or less as you described ... just the first name basis is handled a bit differently usually ... Although at my workplace only the first name is used as well

Awesome piece of art, beautiful style and a very unique setting!
The LHC always fascinated me and I had the pleasure of talking to scientist invovlved in the experiemnts a few years ago while working at a museum which had a special collaboration with CERN. Hope I can manage to go there one day and do a tour.
