Open the CIPO recordAbstract From the Canadian patent
The apparatus and the method according to the invention allow to determine the energy of a ion beam, by directing the beam against a target of a suitable material, which causes elastic and anelastic scattering of the particles, so as to determine the crossover angle for which the energy of the elastically scattered particles equals the one of the anelestically scattered ones and to calculate, from, this angle and from data relating to preselected physical values of the same particle beam, through preselected relativistical kinematics relationships, the energy of the incident beams with an, uncertainty lower than the energy dispersion of the beam.

Why it's free to use
- Filed April 10, 1991. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 10, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 10, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
