Edge of dipole application in envelope mode

[shliu]

Hi Didier,

According to my understanding, the edge of a dipole in envelop mode could be regarded as a kicker. My .dat file is as following:

EDGE 0 800 110 0 0 50 0
BEND 45 800 0 50 0
EDGE 45 800 110 0 0 50 0

The transfer matrix of the third element (the edge of the dipole) is

which means that it's defocusing in H plane and focusing in V plane. The question is, when I check the x' and y' envelop, there's only kick application in x', but without y':

I tried the dipole field map and found the kick effect is obvious in both planes:

Dear shliu,

On my side I see kick in both planes, but I didn't have your project configuration. Please send me your project files (*.ini, *dat), otherwise complicated for me to check your case.

Regards,

Didier

Hi Didier,

Attached the .ini file.

There's an error message when I tried to attach the .dat file, so I put the content here:

EDGE 0 800 110 0 0 50 0
BEND 45 800 0 50 0
EDGE 45 800 110 0 0 50 0
end

Dear shliu,

I fixed the problem in forum about the 'dat' file.
So, using your project, I find for 45° edge, the following behavoir and I found small vertical kick. And if I incease angle to 60° vertical kick become obvious.
