Function and Applications
Compact operating unit for Franck-Hertz experiment to be used with Hg- and Ne-tubes.
In 1913/14 James Franck and Gustav Hertz approved Bohr's model of atoms with this experiment (Nobel Prize: 1925).
Benefits
Automatic detection of tube type and automatic limitation of tube parameter.
Examination by direct reading of displayed values, xyt-recorder, oscilloscope or PC.
From the recorded anode current as a function of acceleration voltage the exitation energy of the atoms can be determined.
Equipment and technical data

Data output: RS232 SubD-socket
Display: 20 mm 7-segment LED
4 operation modes: manually, automatic ramp, saw tooth (oscilloscope) and PC-control
Power control for heater with safety socket (600 W) and type K socket for thermocouples
Socket for 5-pole connection cable for Hg/Ne-tube
