Re: Aperture for EHKICKER, EHKICK, EVKICK

Hi Zhe,

thank you for your reply. i.e. to have the right apertures, I have to add the amount of the aperture reduction to the aperture's values?

Aperture for EHKICKER, EHKICK, EVKICK

Hi all, i have a problem, when i change the values for EHKICKER (HKICK or VKICK) and want to output the twiss, the xApertures and yApertures values are changing...I wonder why? I tried EHKICK and EVKICK, the results are the same (changing the apertures values). Could you please help me get to the bo...

APCONTOUR element

Hi, I tried to use the element APCONTOUR for a KQUAD or DRIFT. By twiss output, I got the aperture of the previous element. By tracking the particle coordinates are lesser than the aperture which I have in the SDDS file for APCONTOUR. The sdds file contains x and y data. " S00QD1D : KQUAD , L = 1.3 ...

Tracking at resonance tune for linear lattice--> emittances grow

Hi, for tracking at resonance tune, i.e. Qx=Qy and for a example lattice just with two Quadrupoles and drifts, I dont expect any emittance changes... this is my lattice: "mqd: MULT, KnL =-0.2169824517, order = 1 mqf: MULT, KnL = 0.2169824517, order = 1 drift1:DRIF, L = 0.65 quad1:Line=(mqd) drift2 :...

Re: correct_tunes

Hi Michael,

you are right in case of two families, it is the same, but in case more than two families, the strengths are not the same...
is it because the system is overdetermined?

correct_tunes

Dear all, if I want to correct the tunes for my lattice. For example for two quads families, I am getting different values for the quad's strengths, if my initial parameters for the quad strengths are different. Although the desired tune value is the same. any explanation? and one other question wha...
