I have found the CERN animal sanctuary, where old mice go to die :(

Compact Muon Solenoid

Compact Muon Solenoid

Have been to a detector on the large hadron collider. CMS is one of 4 experiments around the ring. It is half way round from where I am based andvis a 30 minute bus ride away, across the boarder into France. A Muon is a heavier version of the electron as they are generated when two protons collide. The solenoid is a very strong magnetvwhich is used to bend the path of the muons so their momentum can be found. Compact, this is one of the smaller detectors on the LHC, but still weighs in at 14000 tonnes. It is 80m underground, but it wasnt possible to see it for real today. This is because the lhc is being switched back on tonight after a week to allow for some servicing. Here is a view of the control room as they prepare to switch on, together with a link you can follow to see what is happening on the lhc in real time.

Great to get back from the magnet test facility to find that one of experiments, LHCb have announced the discovery of a new particle with a University of Manchester link

Thought you knew what a magnet was?

Thought you knew what a magnet was?

Have been learning lots about particle accelerators and magnets today. The energy in the beam in the LHC is equal to that of a 20000 ton ship moving at 30 miles an hour. Also been to see how they test the superconducting magnets beforevinstalling in the LHC. Because they are superconducting, they need to be cooled to -271C with superfluid liwuid Helium.

Cloud chambers

Cloud chambers

We have been making cloud chambers today from a plastic tray and a fishtank. They worked really well, as we could observe the tracks from alpha particles, electrons and antielectrons in the condensing cloud. The electrons come from cosmic rays and the alpha particles come from Radon Gas decay.
