6B Class Visiting the Institute of Atomic and Subatomic Physics

Veröffentlicht am 24.10.2017

On Tues­day the 24th of Octo­ber 2017 our class, the 6B, went to visit the Insti­tute of Atomic and Sub­ato­mic Phy­sics in Vienna. We were shown around, our guide explai­ned about their work there and told us about the pro­per­ties of the dif­fe­rent nuclear radia­ti­ons and in what ways they can be used. We also used a device to mea­sure the radia­tion of objects and could see for our­sel­ves, what we had lear­ned and heard of before, e.g. how short ranged alpha-rays are.
Then we could expe­ri­ment with liquid nitro­gen: expe­ri­ence the strange fee­ling when it was flo­wing over our hands, which stayed com­ple­tely dry alt­hough it felt like they did not. And we were amazed by how effort­lessly we could move a super­con­duc­tor, that was cooled down to that state by the liquid nitro­gen, in a magne­tic field.
At the end, we got to see the nuclear reac­tor, that the Insti­tute of Atomic and Sub­ato­mic Phy­sics runs for rese­arch pur­po­ses. We could even go on top of it and look down at its core under­ne­ath the column of water, that stop­ped the radia­tion, and even more import­antly the neu­trons set free by the reac­tions, from hit­ting us. While we were up there, they increa­sed the amount of nuclear reac­tions in the reac­tor, which was only pos­si­ble for the frac­tion of a second, pro­du­cing a flash in the core, that con­ti­nued glo­wing in a bluish light for a few more minu­tes.
Over­all, it was a great expe­ri­ence and a very inte­res­ting after­noon for our class.
