NUST MISIS scientists, inwards collaboration amongst colleagues from both the P.N. Lebedev Physical Institute of the Russian Academy of Sciences too Dagestan State University, own got conducted an experiment amongst the assist of muon radiography method (a modern method of scanning the internal construction of substances) that could plough out to hold out substantial. The enquiry grouping non-invasively scanned the hidden infinite cloak-and-dagger the northwestern business office of the Naryn-Kala fortress (Derbent). The squad is currently processing the information from the sensors.

The 12-meter department is most completely hidden underground, too alone a slice of a dilapidated dome is visible from the surface. The construction dates dorsum to some the yr 300 A.D. Until recently, people inwards the expanse believed this was only an cloak-and-dagger reservoir. However, recent archaeological enquiry suggests this construction is the oldest Christian Temple inwards modern-day Russian. The Arabs controlled much of this expanse afterward their capture of Derbent (around 700 A.D.). Experts believe this to hold out a Christian Temple due to the cross-section of the building, traces of immured entrances, too the location of the structure's walls.
Not all archaeologists concur amongst the concluding interpretation. It is hard to settle their dispute amongst traditional methods because the Naryn-Kala fortress is a UNESCO cultural heritage site. It is non clear how the walls of the building, which own got been exposed to H2O for quite long, volition deed when taken from the ground.

"A grouping of scientists led yesteryear Professor Natalya Polukhina, a leading practiced at NUST MISIS, too including researchers from the P.N. Lebedev Physical Institute of the Russian Academy of Sciences, has applied the method of muon radiography to an ancient construction located inwards the territory of the Derbent Naryn-Kala fortress. The method allows us to 'illuminate' object amongst a size of a few meters to 2 kilometers. Professor Polukhina, who is i of the world`s greatest specialists inwards this method, is straightaway supervising the installation of muon sensors inwards the novel SHiP experiment on the Large Hadron Collider, inwards which NUST MISIS is participating jointly amongst twoscore public leading universities", said Alevtina Chernikova, Rector of NUST MISIS.
The muon radiography method has already proven its effectiveness -- amongst its assist researchers own got already flora a hidden room inwards the Pyramid of Cheops.

The so-called rail detectors, which tin reach the axe non alone illuminate the muons falling on them but besides decide the direction of their displace amongst high accuracy, own got been developed based on muon sensors. By deciphering the readings from these sensors it is possible to brand a three-dimensional picture of a diverseness of objects. By piecing these private scans together, a finished production map of mountains too caves would hold out incredibly accurate. The scans tin reach the axe besides decide the boundaries of dissimilar rocks too their density.
The essence of the muon radiography method is to gain the muon flux density. Muons are unstable simple particles amongst a negative electrical accuse that are born inwards dense layers of the atmosphere due to the decay of protons flight from space. Muons "die" quickly, managing, however, to travel through the whole atmosphere of the footing during their life (10 K muons accomplish every foursquare meter of the Earth's surface every minute), too fifty-fifty to accomplish 8.5 kilometers nether H2O or 2 kilometers into the Earth's crust.

The denser the substance--the faster the menstruum of muons (and the faster they weaken too travel out equally well). Therefore, if nosotros set a corporation object betwixt the "space" too the detector, too thus the detector volition eventually discover the object's silhouette. If in that location are cavities inwards the object, they volition besides travel visible equally muons flight through them overcome a smaller layer of mass.
The preliminary analysis of the fortress conducted yesteryear specialists on topographic maps from NUST MISIS too the P.N. Lebedev Physical Institute of the Russian Academy of Sciences allows researchers to advise that inwards this case, the technique is effective -- the sensors tin reach the axe hold out located to completely scan the object. In addition, the density of the stone too the surrounding stone is to a greater extent than than 5%, which volition besides allow researchers to distinguish the outside of the building.
