1. another novel use of crystals
so far channeling crystals used successfully for charged particle beam deflection (or kickers)
in principle any kicker can be used as a pick-up (reciprocity theorem).
channeling crystals use extremely strong internal electromagnetic fields (in the range of several GV/m or more than 1000 Tesla ) for charged particle deflection
there should also be extremely strong electric and magnetic field gradients in such crystals (i.e. fields interacting with magnetic dipoles)

2. another novel use of crystals - 2
when placing such a crystal in an electromagnetic shielding box (cavity) → additional (as compared to the empty cavity) electromagnetic signals when the charged particles travel through the crystal (like a Cerenkov pickup) but enhanced by the channeling effect
are there any theories/papers/applications/experiments related to this point?

3. crystals as direct n detectors
n’s should have small magnetic moment (around mB) since they have a small rest mass
when a bunch of GeV neutrinos travels through a channeling crystal very very faint electromagnetic signal should be induced from the interaction of those magnetic moments with the huge magnetic gradients in the crystals (leading to some sort of faint wiggling); energy exchange takes probably place in the nano electron Volt range (i.e. at a few MHz) [remember: refractive index of matter for neutrinos]

4. crystals as direct n detectors - 2
with such channeling crystal in a shielded box (cavity ) as neutrino detector, the detection limit would be about Joule per single bunch of neutrinos or Joule with some averaging
if we assume a 1 meter interaction length (cavity size) and GeV neutrinos a relative energy loss due to this effect of less than per meter would be sufficient to see a reasonable signal for bunches of say 1010 neutrinos (and compatible with the fact that neutrinos travel easily through the earth and through the sun)
