Re: deviation between optimizer results and subsequent tracking using these results
Dear Michael, thanks for your response and the explanation. I tried your suggestion with FIDUCIAL="t,light" and yes, in that case the subsequent tracking satisfies the conditions from the optimization. To be on the safe side about the parameter "FIDUCIAL": does the case FIDUCIAL="t,light" mean, that...

deviation between optimizer results and subsequent tracking using these results
Dear Michael, I have an issue with the results from the optimization process: as you can see in the attached files, I defined two different types of &optimization_term, the problem exists with both. First (folder “sene”): If I use &optimization_term term="M18#1.pCentral 48.9237795889796 1e-9 sene", ...

Re: RFTMEZ0: on-crest phase depending on number of cells or cavity length?
Hi Michael, Thanks for your quick response, your explanation makes the behavior comprehensible. Thanks also for your optimization script! I have a few questions regarding this: 1) As an optimization term you use pAverage once and pCentral once. Actually, I have already asked myself at some point, wh...

RFTMEZ0: on-crest phase depending on number of cells or cavity length?
Hi Michael, I want to work with the element RFTMEZ0 in order to investigate the phase slippage and to find the perfect acceleration process. I noticed the following, what I do not understand: the on-crest phase seems to be dependent on the number of used cells (or cavity length). We use 20-cell Tesl...

Re: vary_element for sto variables
Hi Michael, thanks a lot! This method works exactly as intended! One general question: Is it possible to use SD4: DRIF,L=1 LINE=(...,SD4,SD5,...) and &vary_element name=SD5, item=L, index_limit=1001, initial=-1 final=1 &end &link_elements target=SD7, item=L, source=SD5, equation="2 L -" &end instead...

vary_element for sto variables
Hi, is there a analog for "vary_element" in order to change variables which are used with "sto"? The following is written in my lattice file: % 0.0853541 sto DeltaA % DeltaA sto DeltaB % 1.76006 sqr 2 mult sqrt 1.76006 DeltaA - sqr 2 mult sqrt - sto DeltaC SD5: DRIF,L="0.3035 DeltaA +" SD7: DRIF,L="...

Re: vary several elements independently
Hi Michael,
somehow I did not notice that command. After changing it that way, everything works fine and as expected.
Thank you!

vary several elements independently
Hi Michael, I used vary_element for a few investigations. Now I want to vary several elements independently. If I use &vary_element name=MAL item=DP index_limit=11 initial=-0.01 final=0.01 &end &vary_element name=MAL2 item=DX index_limit=11 initial=-0.005 final=0.005 &end &vary_element name=MAL3 ite...

Re: mode of operation of the misalignment DX, DY and DZ in QUAD element
Hi Michael, I am sorry; I read your response and forgot to answer. Thanks for your response and your files. Of course you are right, the values of the displacements are way too big; I only chose them to illustrate my issues and to see differences in the results more easily. The real values for the d...
