Group SECAR2.0
Reaction: 45V(p,γ)46Cr
Beam: 45V13+ of 135 MeV (1% enegry spread)
Matrix:
1.0 | 0.0 | 0.0 | 0.0 | -0.41 |
2.2 | 1.0 | 0.0 | 0.0 | -0.35 |
R11 = 1.0 is “Magnification”, i.e. no magnification provided with the dipole.
R12 = 0.0 is “Focusing”, i.e. no focusing is provided by the dipole.
R21 = 2.2 is approximate “Path length”,which is 0.5+0.78+1.0 meters
R22 = 0.0 mean that output angles does not depend on input angles.
R15 = -0.41 is ToF difference due to different initial position.
R25 = -0.35 is ToF difference due to different initial angle.
Reaction summary for 45V+p→γ+46Cr, Ek(45V)=135 MeV
The maximum γ energy is 8.481 MeV. The minimum γ energy is 7.249 MeV.
The maximum 46Cr energy is 132.634 MeV. The minimum 46Cr energy is 131.402 MeV. The maximum 46Cr angle is 0.13 degrees.
Assume normalized emittance 0.6 π mm mrad provided from ReA3 at 3.0 MeV/u.
Geometric emittance is 0.6/0.08 = 7.5 π mm mrad.
Spot size on the target is ±0.5 mm (full width). Then anglular spread is ±15 mrad.
Adding the effect from the target of 0.13 deg = ±2.26 mrad we get ±17.26 mrad of angular spread:
