 * This energy is achieved by degrading the 10.7 MeV cyclotron energy by 72.6um( 3 mils) Ta foil.

** This energy is achieved by degrading the 67.5 MeV cyclotron energy by 6.35um( 0.25 mils) Ta foil.

#Energy after Ta dispersion foil + SEEM(Al 101.6um) + Exit foil (127um Kapton) + air gap

By changing the Cyclotron Energy and the Ta foil thickness other energies can be obtained.
