Scientists have now created a beam of matter waves, is this what the
Dendera tubes do?

In the Munich experiment, a dilute gas of rubidium atoms is captured in
a sophisticated low-power magnetic trap and cooled down to reach
Bose-Einstein condensation.
With the help of a radiofrequency field the scientists flip the atomic
spin so that atoms are allowed escape from the magnetic trap. In vacuum,
the atoms are accelerated by gravity and form a parallel beam of
coherent matter waves.
It the radiofrequency field is turned on before condensation sets in,
the atom laser can only reach threshold, if there is laser "gain".
Unlike a Bose-Einstein condensate, such a laser relies on matter wave
amplification by stimulated elastic scattering of rubidium atoms just as
an optical laser relies on light amplification by stimulated emission of
radiation.
