Each year, CERN welcomes around 100,000 visitors onsite. Many of these visitors take a short trip from the laboratory's main site in Meyrin to the French commune of Cessy to see one of humankind's modern scientific marvels: the CMS detector. The 14000-tonne detector is located in a vast cavern around 100 metres (or about 30 storeys) underground, with an adjacent cavern housing several data-collection and power-distribution devices.

On 29 May, together with my colleagues and a group of enthusiastic students from Bulgaria, we descended 100 metres underground to visit places where only CERN collaborators have access rights.
Picture it: more than 200 volunteers, several tiring weeks of preparations, over 4500 visitors and lots of happy faces!
Happy birthday CERN!
2014 marks a special occasion for CERN: its 60th anniversary. To celebrate, CMS opened our doors to our neighbours for an entire weekend (24 and 25 May) and the response thrilled us.
