LHC is hibernating until February next year, outreach efforts are not on hold. Here in Germany, there is a nice exhibition on tour, called "Die Weltmaschine". This means literally the "world machine" – somewhat better than the "big bang machine", but finding a catchy but not misleadingly bombastic name for the LHC seems to be a challenge.



Anyway, the exhibition, organized by DESY, the German particle physics laboratory based in Hamburg, was on display this December in Heidelberg, in the large foyer of the Kirchhoff Institute for Physics of the University. Experimentalist from Heidelberg are contributing to the ATLAS, ALICE, and LHCb experiments.



The exhibition provides a nice introduction in the known facts and open issues of particle physics, and in the techniques to accelerate particles and detect and analyse the collision products. I was there on Saturday afternoon last week, and was surprised that quite a lot of people were around, despite the cold and the snow that had gripped Heidelberg that weekend.



The most fascinating exhibit to me was a spark chamber, where the ionisation of gas by charged particles triggers sparks between high-voltage wires.



Although this is detector technology that is not used anymore at the LHC, it is compelling how it makes visible the constant shower of ionising particles in the cosmic radiation, which we usually are completely unaware of. It was quite easy to catch a couple of events with my digital camera, just by photographing the chamber at random moments:





The next stopover of the exibition will be Frankfurt – if you are around by chance in the second half of January, it is worth a visit.

Weltmaschine

While the LHC is hibernating until Feb subsequent year, overdo efforts have been not upon hold. Here in Germany, there is the good muster upon tour, called "Die Weltmaschine". This equates to literally the "world machine" – rather improved than the "big crash machine", though anticipating the familiar though not misleadingly egotistic name for the LHC seems to be the challenge.



Anyway, the exhibition, orderly by DESY, the German molecule production laboratory formed in Hamburg, was upon arrangement this Dec in Heidelberg, in the vast corridor of the Kirchhoff Institute for Physics of the University. Experimentalist from Heidelberg have been contributing to the ATLAS, ALICE, as well as LHCb experiments.



The muster provides the good introduction in the famous contribution as well as open issues of molecule physics, as well as in the techniques to accelerate particles as well as detect as well as break down into parts the collision products. we was there upon Saturday afternoon final week, as well as was astounded that utterly the lot of people were around, notwithstanding the cold as well as the sleet that had gripped Heidelberg that weekend.



The many erotically appealing vaunt to me was the spark chamber, where the ionisation of gas by charged particles initiates sparks in between high-voltage wires.



Although this is detector record that is not used any more during the LHC, it is constrained how it creates manifest the consistent showering of ionising particles in the vast radiation, that we customarily have been totally unknowingly of. It was utterly easy to locate the integrate of events with my digital camera, only by photographing the cover during pointless moments:





The subsequent stopover of the exibition will be Frankfurt – if we have been around by possibility in the second half of January, it is value the visit.
