You can do so by connecting to the CMS web site.
For those of you still unconvinced: CMS is one of the four main experiments at the Large Hadron Collider, one of the two which discovered the Higgs boson in 2012, it is the most massive, and by far the most photogenic - just check it out today to get convinced of the fact. Or see below:
As for GEM detectors, they are made of thin layers of insulating material with tiny pinholes that accelerate the electrons passing through. When a charged particle releases ionization in the detector, the electrons get multiplied when passing through the high electric field in the holes, and release a detectable electric signal. One can thus manufacture large-area, precision detecting sheets with relatively cheap technology.
I will stop writing now as otherwise you'll miss the broadcast! It is a live broadcast in 360 degrees video... Should be fun!!
Tommaso Dorigo is an experimental particle physicist who works for the INFN at the University of Padova, and collaborates with the CMS experiment at the CERN LHC. He coordinates the European network AMVA4NewPhysics as well as research in accelerator-based physics for INFN-Padova, and is an editor of the journal Reviews in Physics. In 2016 Dorigo published the book “Anomaly! Collider physics and the quest for new phenomena at Fermilab”. You can get a copy of the book on Amazon.
