You ’d be surprised at how many time someone has enquire whether the Large Hadron Collider ( LHC ) could collide everyday things , like a sandwich . The answer is , not quite … but almost ! It ’s sort of a long narrative , and the account might surprise you .
In fact , physicsts latterly put something strange into the LHC in Geneva , Switzerland . For just a few time of day this past October , scientist at the world ’s largest , most expensive gamey - energy cathartic experiment swapped out the common petite proton and large lead sources and instead thrash together intermediate - sized atomic number 54 corpuscle . They hoped to learn more about a mysterious phase angle of matter that may have exist in the minute after the Big Bang .
“ The hit of these … nuclei can produce the quark gluon plasm - like medium in a controlled environment , ” scientists Achintya Rao , Marta Verweij , and Camelia Mironovwrote , “ allowing us to journey back in fourth dimension nearly 14 billion years and observe conditions of the early population . ”

We typically mean of the population ’s hooey as being made from atoms arranged as solids , liquids , or gases . But perhaps during the creation ’s high - energy origins there was another phase , a liquid whose constituent part were quark cheese , the smallest units that make up proton and neutron .
Scientists have consider some pretty narrate evidence of this quark - gluon plasma by clash heavier lead , atomic number 79 , or copper atoms stripped of their negatron . They ’ve likewise seen steer of it by clash protons with lead-in , or evenjust proton , the positively charged pieces that make up atomic nuclei . The researchers desire to understand how this quark - gluon plasma depart base on the size of it of the clobber they collided . Gold and lead atom are comparatively pretty big , while protons are very small . Xenon atoms are right in the midway — meaning this study can help take in the holes .
“ Our field has historically see a lot from being able to deepen atomic size of it , ” Dennis Perepelitsa , physicist at the University of Colorado , Boulder , told Gizmodo . “ For example when [ the Relativistic Heavy Ion Collider at Brookhaven National Lab in New York ] run bull - copper rather of their usual gold - gold , it was apocalyptical and result in a major epitome transmutation . ” Changing the collide nuclei can change the size of it , temperature , form , and other properties of the result quark - gluon plasm .
translate how to switch elements requires a noesis of how the LHC works . The most notable experiment at the LHC is just the biggest ring in a serial of smaller , turbocharging racetracks used to speed up bunch of atom . This begins either with a bottle of atomic number 1 accelerator or a very pure lead shot with only a single isotope of lead — corpuscle that all have the same number of neutral neutron speck . The bottle ’s flatulency valve is opened or the lead pellet gets vaporize , then the particles head up ontheir journeythrough straight line and loop , are strip of their negatron , and are sometimes diverted into other experiments along the way of life , before entering the 17 - mile - round LHC ring .
So , switch between lead and xenon involve substitute the lead pellet with xenon gas — an easier origin to trade with , John Jowett , particle accelerator physicist at CERN , narrate Gizmodo . Then , they just need to configure and calibrate the machine and its magnets .
Why xenon ? Another experiment had asked for accelerated Xe atoms , so the quark - gluon - blood plasma - meditate physicists seized the opportunity to make measure of their own . And the swap only took half a Clarence Shepard Day Jr. to do . “ I reckon we pass about 10 hours setting up the xenon beam in the LHC , ” enounce Jowett . “ That ’s a singular matter — you’re able to do things like this with a carefully fabricate architectural plan . ”
As to whether you may collide a sandwich , it would need to be vaporized first , and its atoms probably would n’t make it very far through the series of racetracks . scientist tune up the experiment ’ magnets to speed up very specific combinations of nuclear charge and people , so any of the element that do n’t fit the criteria will be lost early on , said Jowett . And if an atom or two did make it into the main annulus of the Large Hadron Collider , there plausibly would n’t be enough stuff to bring forth any collisions — the LHC beams collide lots of mote or proton at the same time . “ You have to get thing right all the way through , ” he said .
Without being able-bodied to bring forth collision for the giant detectors to spy , accelerating a sandwich would n’t be very interesting . Accelerating and colliding xenon particle was very interesting , though . The few hour of data - collecting result in scores of experimental result , presented last weekat the 2018 Quark Matter league in Venice , Italy . The researcher noticed some modest differences between what they measured and what they require from the collision , which may be important for understand the nature of the quark - gluon plasma .
The collisions were in the main a feasibleness mental testing , say Perepelitsa . Smaller particle could deliver more collision for various technical reason , so scientist want to know if they can actually clash modest atoms . Xenon serves as an interesting proof - of - concept that may lead to collide even smaller atoms , like argon , in the future . “ These collision would create small but explosive quark cheese - gluon plasmas , ” said Perepelitsa , “ and we would have just perfectly colossal statistics for explore them . ”
So , no , you ca n’t collide a sandwich . But putting unusual thing into the Large Hadron Collider can lead to some interesting scientific resultant role .
