I've been able to buy a Neon filled Franck-Hertz tube together with its control unit. Everything looks fine, the output voltages from the control unit are correct and the tube seems to work just fine, however I can't get the experiment to work properly.
Is there anyone here on the forum that can help me out? I have checked all voltages and used this guide: http://www.bastgen.de/schule/physik/13/Material/Franck-Hertz-Neon.pdf The control unit can be seen here: https://www.uranmaschine.de/87051.Neva_6751_Franck-Hertz-Roehre_mit_Quecksilber/87051.Neva_6756_Franck-Hertz-Betriebsgeraet_hires.jpg What I am trying to do is specifically the part where you are supposed to get one or more clusters of neon atoms being excited like in this photo: https://www.leybold-shop.com/media/phk/images/versuche/P6243_Schirmbild.jpg [image: https://www.leybold-shop.com/media/phk/images/versuche/P6243_Schirmbild.jpg] -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
