    En el CERN, situado entre Francia y Suiza, hay dos experimentos de propósito general que utilizan el acelerador de partículas LHC (o Gran Colisionador de Hadrones). Uno de estos experimentos es el CMS (o Solenoide Compacto de Muones) y sus objetivos son descubrir el Bosón de Higgs (bastante escurridizo), buscar evidencias de la supersimetría, estudiar las colisiones de iones pesados y explorar la materia a nivel de los TeV. El funcionamiento se resume en introducir un haz de partículas cargadas en un tubo circular y acelerarlas mediante el uso de potentes imanes, hasta que se hacen colisionar con otras partículas en el interior de un detector como el de la imagen. Mediante calorímetros ultrasensibles se detectan las trayectorias y energías de las partículas resultantes de los choques, se recogen los datos y, a través de los cables azules, se envían a potentes ordenadores en los que se analizan y se proponen modelos que expliquen las colisiones. Estos experimentos sirven para avalar o refutar las teorías que se van proponiendo acerca de la constitución de la materia a nivel subatómico, algo que escapa a mi modesto conocimiento de bioquímico.

    The CMS (Compact Muon Solenoid) experiment is one of the two large general-purpose particle detectors built on the LHC (Large Hadron Collider) at CERN (between Switzerland and France). Its supposed goals are exploring matter physics at the TeV scale, discovering the Higgs Boson, studying aspects of heavy ions collisions and looking for evidence of supersimmetry. How does it work? A charged particles beam is introduced in a circular pipe and they are accelerated with very powerful magnets, until they are forced to collide against other particles within this huge detector. By means of ultrasensible calorimeters, the resulting particles are tracked and their energies measured. Through the blue wires, the data are sent to supercomputers which analyse and check if the proposed models explain the collisions and resulting particles, which later is used to endorse or refute the theories about the constitution of matter at subatomic levels. As far as my knowledge of Fundamental Physics is limited to a biochemist's, if someone wants to know how it works and which are the different components of the detector, better go to:

      Well, thefost, that's what happens when your best friend is a big brain in Fundamental Physics: the conversations are about singularities, bigbangs and the weak interaction and we have met at places like Max-Planck-Institut für Phisik in München or in CERN in Geneva!! Maybe someday I'll met him in Los Alamos ;-D!!!

      Impressive shot! You had an amazing opportunity photographing there! Lets hope this device leads to a better understanding how the universe works :).

      Thank you, Marc! In fact, it was an almost clandestine opportunity, as standard visitors are not usually allowed to go downstairs right to the heart of the accelerator. My friend, who is working in the DAS (Data Acquisition System), explained me "in situ" the whole process from the colliding particles to the data interpretation, in a guided tour that has nothing to do with the visits made by scholars.

      Wow! What an awesome opportunity you had to get a peek inside such an amazing place! Thanks for grabbing a shot and sharing!

      Thanks a lot, Garret! In fact I grabbed more than a hundred shots in the different facilities of the CERN, but this one picked up my attention because of the wires and the colours. Unfortunately didn't think of taking a pano, as the corridors along the detector were very narrow... maybe next time!

      Mensch, digital cat! Ich dachte, ich war der einzige Freak mit solchen Fotos. Deine Sammlug ist beeindruckend!!

      Hola, soy el administrador de un grupo llamado Industrial Archaeology Map y nos encantaría agregar esto al grupo.

      Thanks for your invitation, although I don't know if this ultramodern detector will fit an Industrial Archaeology group...

      WoW, great photo from this amazing piece of engineering!
      Alos fine single raw processing.

      Hvala, Boris! I was down there with a close friend and took a lot of pictures, but this one was especially interesting because of the wires and the man on the right showing the real size, and the HDR processing was quite good-looking too!

      Now this is a bizar concoction of lines and colors.
      + Composition is very interesting, it's like a postmodern abstract painting. Great colors (thanks to pseudo-HDR).
      - The scaffolding on the right can be seen as a disturbing factor in this composition (even though you framed it quite nicely). Slightly inadequate DOF (the top is out of focus). A smaller aperture would solve this - but then you'd either have to pump the ISO even further or shoot from a tripod.

    18. Panoramyx 71 months ago | reply

      Thanks a lot, tdvos, for your constructive criticism! The scaffolding was unavoidable as there were some maintenance going on in the detector. That was good in two senses: I had the opportunity of taking a photo of inner parts that are usually closed in the cylinder, and the presence of a engineer in the scaffolding allows us to get an idea of the real size. The ISO had already been pumped up to 800 and the noise in the 400D is too annoying at higher levels, so I preferred to sacrifice the DoF, as I didn't carry a tripod. By the way, I'd preferred to shot a pano, but we were in an strait aisle right between the wall and the detector...
