|
Analyzed data : run 0331
Used reaction : 7Be(p,d)6Be (ground state and 2+ state 1.6 MeV are mainly populated).
Method;
X and Y position on each CATS is compared with position on the target deduced by both CATSs. Assuming the beam profile is not changing, the correlation of these positions can by fit by linear function.
The position on the target can reconstructed with only one of the CATSs, with worse resolution. Beam angular spread seems rather small than angular deduced by only 1 CATS.
In terms of the excitation energy resolution,
sigma of the Subtraction of (both CATS Ex)-(only CATS1 Ex) ~ 0.53 MeV
sigma of the Subtraction of (both CATS Ex)-(only CATS2 Ex) ~ 0.32 MeV
Original estimated Ex resolution is ~ 1 MeV, so not so bad.
In terms of the background from the frame of the target cell, roughly can be removed by target position. Near the center part gate should be more secure. |

For (p,t) reaction, the value of the mass for N=1 isotone is taken from proposal, so it can be shifted.
