Charles, Unfortunately, there's no way to control the ticks on the color bar. If you just want to know the minimum St, try % sddsprocess run.finc -pipe=out -process=St,min,%sMin | sddsprintout -pipe -parameter=StMin You could also try a log-scale plot % sddsprocess run.finc -define=col,LogSt,"St 1e-...

Simona,

Sorry about the crash.

The LSC_LOW_FREQUENCY_CUTOFF0 value should be less than the LSC_LOW_FREQUENCY_CUTOFF1.

Also, LSC_HIGH_FREQUENCY_CUTOFF0 and LSC_HIGH_FREQUENCY_CUTOFF1 are more important for controlling noise.

Charles, The way you set up the vary_elements commands isn't right, because you gave the same index_number for both. Give Q1 index_number=0, and Q2 index_number=1, so they are varied on separate indices. Once that's done, try this: % sddscollapse run.fin run.finc % sddsplot -column=Q1.K1,Q2.K1 run.f...

Max,

You can do this by inserting a WATCH element in the beamline, as follows:

w1: watch,filename="%s.w1",mode="parameters"
ring: line=(w1, ...)

With this, you can plot the number of fraction of particles left using
% sddsplot -column=Pass,Transmission <whatever>.w1

Olivia, There are two problems I see: 1. The VOLT parameter is set to the same value in both element definitions. However, they should have a ratio of the number of cells (156), since VOLT value is the total voltage, not the gradient. 2. When splitting linac cavities, it is advisable to tell elegant...

Olivia,

Sorry, I'll need the daresburyastrain.sdds, wakefieldlong.sdds, and wakefieldtran.sdds files as well.

Olivia,

Can you also post a .ele file that illustrates how you are using this lattice?

Joel, The QUAD element is a standard thick-lens matrix treatment. See, for example, SLAC-75 Equation 55. You can include linear fringe effects with the FFRINGE parameter, which is described a little bit in the manual at http://www.aps.anl.gov/Accelerator_Systems_Division/Accelerator_Operations_Physi...

Joel,

Another tip: if the file is very large, it might be faster to look at another, smaller file that is generated by the same elegant run and will have the same number of pages.

Joel,

You can use "sdds2stream -npages=bare <filename>" . This program also has the ability to report the number of rows (-rows=bare).
