Experimental verification of the Casimir attractive force (Lamoreaux) |
http://xxx.lanl.gov/abs/quant-ph/9907076
The author states the (first?) experiment was conducted
using a torsion pendulum, the apparatus constructed
"with junk lying around the lab ... about $600".
Have any subsequent experiments been conducted in
which the apparatus is permitted to move such that
the gap between two plates changes its orientation
wrt the horizontal and vertical?

Hmmm, don't know. Why?
Experiments have moved beyond torsion pendulums to look at suppressed
emission. See for example:

If the cavity is adjusted properly, you can get stimulated emission of
photons; a Casimir laser.
