Query: Technologies for tunable gamma-ray lenses   The tunable gamma-ray lens has turned out to be a promising alternative to
the classical fixed-energy Laue-lenses discussed in the past. We describe here
our development work on a miniature pedestal with one-axis tilt adjustment. We
also outline our design for an optical system, capable of monitoring the
alignment of the many crystals needed. An added benefit of the tunable crystal
pedestal is that it relieves both the demands for high precision in the crystal
mounting and the stringent requirements for long-term stability of the support
platform on which the crystals are mounted. Moreover, mounting the individual
crystals on separate pedestals facilitates the use of double layers of
crystals.
