Demonstration TubesU19155 Demonstration Electron-Beam Deflection
TubeFor investigating electron beams in electric and magnetic
fields and determining specific charge e/m through compensation of
magnetic deflection by electrostatic deflection. Also for
estimating the speed of electrons.The integrated plate capacitor
allows electron beams to be deflected electrostatically and by
using a set of demonstration Helmholtz coils (U19105) magnetically.
The path taken by the electron beams is rendered visible on a
fluorescent screen with a centimeter grid inclined by 15 with
respect to the beam axis. Equipped with an integrated focusing
electrode system. Filament:< 7.5 V AC/DCAnode voltage:1000 V to
5000 VAnode current: typically 1 mACapacitor voltage: max. 5000

AU19170 Demonstration dual-beam tubeHelium filled tube with a
tangential and axial electron gun. The electron paths arerendered
visible in the form of fine luminescent beams through impact
excitationof the helium atoms.For determining specific charge e/m
from the diameter of the electron beam inthe case of tangential
bombardment and a perpendicularly aligned magnetic field,and
observing spiral paths of electrons in the case of axial
bombardment and aco-axial magnetic field.Gas

AU19170 Demonstration dual-beam tubePower SuppliesAC/DC Power
SuppliesHigh-performance power supply units for continuously
adjustable Dc and AC voltages, with digital display for voltage and
current readings, switchable for adjustable DC and Ac output.The DC
voltage output can be used as a constant voltage source with
current limitation or as a constant current source with voltage
limitation. Sustainedshort-circuit-pool and external-voltages
resistant. AC voltage output is is equipped with electronic
overload protection.In the case of apparatus u201070 the DC and AC
voltage can be operated simultaneously with maximum load. The
device U21080 is also equipped with two ac fixed voltage output 6v

continuously adjustable AC/DC power supply units are paraticularly
suitable for experiments for students and trainees. The out-puts
are galvanically isolated. A pushbutton can be used to turn the
capacitor filtration of the output direct voltage on and off
