Hi, I cannot recall (and find) how to install sddsoptimize from source. I understand it is part of the SDDSepics package but do I need to install the full EPICS package or simply the EPICS configuration file? I tried with the latter but the compilation abort with the message below. Thanks! -- Philip...

Thank you Michael, You are right I got confused and actually mistyped my indices (I am actually interested in constraining both R76 and R67 too). However for R67 I think my formula should indeed be: "pCentral pCentral * 1 + sqrt sto gamma ; -1 gamma gamma * / 1 + sqrt sto beta; beta c_mks * R65 sto ...

Hi, I have been struggling with imposing lattice constraints involving matrix elements that contain the longitudinal coordinate "s" while dealing with low energies beams. After some exchange with Michael Borland, I introduced a R76=d\delta/dt and try to impose a constrain on this element. Right now ...

Hello,
Is there somewhere a list of allowable parameter that can be used as an equation in the optimization_term? Thank you, -- Philippe.

Michael, This is a "companion post" to my recent post on the RFDF element issues. I would like to track a distribution through a beamline, rematch the output to my desired value and backtrack it to figure out what should be my initial distribution. I am including an simplified example of what I am d...

Michael, I am now pretty sure the RFDF is the problem. Again I am tracking to first order with L=0 so that the RFDF should behave as a thin lens. In this case the beamline I attached in my post of yesterday should perfectly exchange the longitudinal and horizontal emittances. It does not while it do...

Michael, I think there is still an issue. I added the center element (before and after my MATR element) and although the rms properties seem to agree the longitudinal phase space have discrepancies (I am looking at sddsplot -column=t,p com*.out -graph=dot,vary -mode=x=center in the files I sent yest...

All, I would like to model a thin-lens deflecting mode cavity. If I set L=0 in the RFDF element and inspect the matrix provided by runin the testrfdf.ele command file, I get the usual think-lens matrix for a deflecting mode cavity (TM110). I inserted this matrix into a beamline and ran comprfdrMAT.e...

Hi Yusong, You are right the gapack is part of the latest SDDS package. However on my system (I just updated SDDS), doing a make MPI=1 from the SDDS directory did not produce the libgapack.a in the lib directory I had to manually go into the pgapack subdirectory and do a make MPI=1 from there. Maybe...

All, I am trying to install Pelegant from source and have an issue when compiling it. I use the makePelegant script and it complains about a missing library: make[2]: *** No rule to make target `../../../../../epics/extensions/lib/linux-x86/libpgapack.a', needed by `Pelegant'. Stop. I looked for thi...
