Rare wild Orchids at CERN MeyrinLife at CERNBUL-PHO-2005-016There are several "Floral Nature Reserve - Late Mowing" zones at CERN Meyrin. The blossoms of a rare and a not so rare type of wild orchid are currently in flower. The rare one is the bee orchid (Ophrys Apifera) which is a protected perennial. They are very unusual and in some years can appear in great numbers and then sometimes only reappear after a decade. They live in a symbiotic relationship with a soil-dwelling fungus. Its name stems from the fact that its brown, furry lip resembles and smells like a female bee, a mimicry used to attract drones to aid in pollination. The much more distributed species is the pyramidal orchid (Anacamptis Pyramidalis), which due to its size and its bright pink colour is already visible when you pass by in your car.2005-06-04http://cds.cern.ch/record/845144http://cds.cern.ch/record/845144oai:cds.cern.ch:845144BUL Collection.

The top half of the photographs show the magnet with its 44 expansion and recompression tubes (large white circles) and its 44 motors controlling the safety valves (small black and white circles). The chamber itself is inside the magnet. The tanks of the expansion system had been reinstalled on the trolley in the foreground. A large number of struts had been fitted to the trolley to give it added rigidity. 1973 http://cds.cern.ch/record/2039189 http://cds.cern.ch/record/2039189 The COMPASS experiment Detail of one of the magnets on the Common Muon and Proton Apparatus for Structure and Spectroscopy (COMPASS) experiment. COMPASS studies the structure of composite particles which interact via the strong force, called hadrons. These have a complicated internal structure due to the nature of their force carriers, gluons, which can form self interacting bunches called glueballs. 1999-11-16 http://cds.cern.ch/record/2614706 http://cds.cern.ch/record/2614706 Images reproduced from original 24x36mm slides - Digital Memory project.

Usually, storks migrate twice a year. The first trip, the prenuptial migration, takes the birds from their wintering grounds to their nesting grounds. The second trip, the postnuptial migration, goes in the opposite direction and takes the storks to their winter quarters. It is most often seen around the end of August, beginning of September.2021http://cds.cern.ch/record/2780011Life at CERNhttp://cds.cern.ch/record/2780011oai:cds.cern.ch:2780011General Photo 10th Anniversary of the first collisions at the ISRCERN Events and VIP VisitsCERN-PHOTO-8103636Celebration of 10 years of proton-proton collisions at the Intersecting Storage Rings.Cutting the cake K.

After having undergone several high intensity beam impacts at the HiRadMat facility in August, the TDIS HRMT-45 module starts to be disassembled by the EN/STI-TCD and EN/SMM-MRO teams in the bunker 867-R-P58 for the post-irradiation analysis. The ultimate goal is to verify that all the equipment components remain fully functional after the high thermomechanical loads they were subjected to during the experiment. Such loads were equivalent to those likely to occur inside the TDIS during future operation HiLumi beams. Given the significant radioactivity of the module, some dismantling activities are to be performed by means of robots in order to minimize the dose taken by personnel. The robot appearing in the pictures is the in-house developed CERNbot, which was able to unfasten the tank upstream and downstream transitions while being operated remotely from another room. This was possible partly thanks to some robot-friendly solutions implemented in the TDIS HRMT-45 design agreed with MRO. The next step following to the tank opening is the metrology of the jaws, which flatness level measurement is expected to return similar values with respect to the pre-test condition.2018http://cds.cern.ch/record/2646413Acceleratorshttp://cds.cern.ch/record/2646413oai:cds.cern.ch:2646413General Photo Brice, MaximilienPrototypes of the ATLAS inner tracker (ITK) pixel detectorPhotolabCERN-PHOTO-201902-038This is a prototype for a new pixel detector for the ATLAS Experiment. The future pixel detector will be part of a new, all-silicon inner tracker (ITk) currently under development for the High-Luminosity phase of the LHC (HL-LHC). The ITk will replace the current inner detector, using state-of-the art silicon technologies to cope with the increased rate of collisions expected at the HL-LHC. As shown in the image, the pixel outer barrel region will feature sensors tilted with respect to the beam axis, helping to improve the tracking performance while reducing the total silicon area.2019http://cds.cern.ch/record/2661761Experiments and Trackshttp://cds.cern.ch/record/2661761oai:cds.cern.ch:2661761General Photo Brice, MaximilienCMS detector modules for the "HGCAL" project (High Granularity Calorimeter).PhotolabCERN-PHOTO-201812-333Prototype detector modules for the CMS "HGCAL" (High Granularity Calorimeter) phase-II upgrade project.
