Gas Scattering lifetime
Dear Dr. Borland, Sir, I tried this gas scattering lifetime example, while using Postprocess command as elasticScatteringAnalysis -tracking run1.eslos -twiss run1.twi -output run1.esanal -pressure PARPressure2015-11-11.sdds -verbose 1 error message: unknown switch: tracking (screenshot attached) sim...

Re: Transient beam loading with passive Harmonic cavity
Dear Dr. Borland, Please find attached example file for simulation of Touschek lifetime in presence of passive harmonic RF cavity which I received from you earlier. I want to study Touschek lifetime with uniform and non uniform RF buckets fill, due to transient beam loading, bunch length will be dif...

Re: Transient beam loading with passive Harmonic cavity
Dear Dr. Borland, I use elegant example file "touschekWithHHCFromTracking" for simulation of Touschek beam lifetime with a parasitic 4th-harmonic RF cavity and got results. In this example "generate bunch train" command is not used. Can you please send example file in which bunch train command is us...

geneticoptimizer example
Hi, I run genetic optimizer, an example file of APS with optim1.sdds. I need help for how to change column value and parameter value in optim1.sdds. I have column and parameter separately. How we can change the column value and parameter value and combine it to make new optim1.sdds. I am attaching o...

Re: Beam instabilties in electron storage ring
Dear Dr. Borland, I tried to estimate filter coefficients using Basic.twi file using command TFBFirSetup. I need help to know how we define the driver strength in lattice.lte file (example file multibunchCollectiveEffects) xdriver: TFBDRIVER,ID=x-plane,output_file="%s.xfb",strength="-20 rec" ydriver...

Re: Beam instabilties in electron storage ring
I want to do simulation study in ultra low emittance ring using transverse bunch by bunch feedback. To understand the simulation, I am using example file of collective effect in APSU ring. I tried to estimate the filter coefficient as shown in lattice.lte file for DRIVER1 and DRIVER2 (file attached)...

Multi-particle tracking in presence of long range resistive wall in ultra-low emittance ring
Hi, I am using elegant 2020.5. I tried to generate bunch train using elegant example but facing problem.First, I run generateBunch command and get bunch.sdds file but when I use command generateBunchTrain I get generateBunchTrain command not found. The screen shot of command and bunch.sdds file is a...
