+ | This pulled the three sets of rays in the image very close together. | ||

+ | We plotted theta4(recoil angle) vs theta3(gamma angle) | ||
+ | It seems the larger the recoil cone, the larger the gamma cones (equally forward & backward) | ||
+ | Ours did fit both separators. If it didn' | ||

+ | 4. b) | ||
+ | We plotted theta4 (recoil angle) vs E4 (recoil E), and found dE/E = +/- 0.7% | ||

+ | 7. Q2 converged at, Mas. Res.Power at FP2= 751, Resol. by max. ray= 950. This was after the fit, minimizing the inverse of the first order resolving power. Which didnt differ from before changing length. | ||
+ | B before was=0.111727 | ||
+ | B after was= 0.115052 -> 3% different | ||
+ | These were done with cosy 9.1 FRIB which is not the optimal version to use. Version 10 gave close numbers (747 and 946). did not have time to redo with other quads and other version. | ||
