BEAM-1 LINE (Current design)
1.6 m
Lquad=180 mm
0.6 m
Beam at the entrance of scanning magnet 1
Beam at the output of scanning magnet 2
Horizontal size (FWHM)=8.7 mmVertical size (FWHM)=9.08 mm
Max. x-displacementdue to hor. kick given by M1
M1 and M2 are approximated as two steerers placed in the middle of the magnets. Each particle gets a kick depending on its energy
IRRADIATED FIELD: 100x100 mmOne row, nsteps=10Step length=1 FWHM
Bx vs t for one row scanning time=100 msec
Hor. centroids displacement
F=100 Hz
IRRADIATED FIELD: 100x100 mmOne row, nsteps=10,Step length=1 FWHM
F=100 Hz
IRRADIATED FIELD: 100x100 mmOne row, nsteps=20Step length=FWHM/2
F=200 Hz
