+ | * Effective field length of Q2 was increased by 3% and the drift lengths either side were adjusted accordingly, | ||
+ | * The mass resolution was then optimised by minimising the function OBJ := 1/ | ||
+ | * This would increase the mass resolution to values of up to 85,000, however the emittance was very large. | ||

+ | * We realised that we should alter our objective function, in order to re focus our beam. This was achieved with the function OBJ := 1/ | ||

+ | * This optimisation improved the mass resolution from 640.86349 to 724.5905, while still focusing. | ||
