Concorde Icing Experiments 1970s

I'm looking for any information or photographs relating to the icing
experiments carried out with the Concorde during the early 1970s.
The experiments consisted of the Concorde flying behind a water
spraying aircraft (a A&AEE Canberra). Fine particles of water were
sprayed by the Canberra and the amount of ice accretion on the
Conrcorde was measured.
I would be very grateful for any information, even memories , of these
trials.
