Hi all,
Thanks very much to all of you for such a prompt reply to my original
query. Many of you expressed some concern about the relative orientation
of the two crystals so as to implement type-I doubling at each
step. I did take into account this fact, i.e. the axis of the second
xtal is perpendicular to the first. Any additional tips ???
Thanks,
Felix
