This emittance grow is possibly due to the optics aberrations. That is because the input COSY file does a 4th-order-calculation. Also the measured points don't fit the parabola ideally, i.e. the optics is non-linear.\\ | This emittance grow is possibly due to the optics aberrations.

+ | The effective length of Q2 was reduced by 3% to 0.291m with the drift lenghts before and after increased by 0.0045m.\\ | ||
+ | This led to a mass resolution change from 445 to 102 for the standard particle of the script. | ||
