Magnet layout with CSR elements

[tcharles]

Hi Michael,

It seems that the magnet layout output becomes a little strange when CSR elements are used (namely CSRDRIFT and CSRCSBEND).

For example, here's a section of bunch compressor and you can see that D_SIDE_BC1 starts at s=3.247044e+01 and DIP2_BC1 also starts at s=3.247044e+01. I've attached an image of this plotted and you can see the magnet elements all have a slanted edge.

3.141949e+01 DIP1_BC1

3.247044e+01 D_SIDE_BC1
3.701451e+01 D_SIDE_BC1
3.247044e+01 DIP2_BC1
3.701451e+01 DIP2_BC1
3.751521e+01 DIP2_BC1
3.751521e+01 DIP2_BC1
3.701451e+01 DIP2_BC1
3.701451e+01 DIP2_BC1
3.751521e+01 DIP2_BC1
3.751521e+01 W2_BC1
3.751521e+01 D_CENT_BC1
3.826521e+01 D_CENT_BC1

Is there any reason behind this? And is there a way to plot the magnet layout in it's more standard form?

Thanks in advance,
Tessa

Tessa,

This is a bug in older versions of elegant. If you update to the latest version, it should be resolved. If not, please let me know.

Hi Michael,

Thanks for your response.

Another related question - is there an easy way to offset the magnet layout plot? I have a plot where the magnet layout profile overlaps some of the data. It would be great if I could just lower the magnet layout profile. Do you know of a way to do this?

Thanks so much,
Tessa

Nevermind,I found a solution!
For anyone else wondering, 'sddsprocess -define=col,ProfileOffset,"Profile 5 -" xfel.mag', works fine.

Tessa,

You can also do this without modifying the file, e.g.,

Code: Select all

sddsplot -col=s,betax run.twi -unsup=y -col=s,Profile run.mag -offset=ych=-5

Another useful feature of sddsplot is overlays, e.g.,

Code: Select all

sddsplot -col=s,betax run.twi -unsup=y -col=s,Profile run.mag -overlay=xmode=norm,yfactor=0.04
