modulate_elements command

I need help to know about the expression of modulation amplitude expressed in RPN in modulate_elements command as follows: &modulate_elements name = Q, item = TOTAL, expression="3.68e-6 / 5000 / 1 min2 abs" multiplicative=1 differential=0 &end What is the value of RPN expression "3.68e-6 / 5000 / 1 ...

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...

Multi-particle tracking in presence of long range resistive wall in ultra-low emittance ring

Can we include Intra Beam Scattering (IBS) for the study of beam instability in presence of Long Range Resisitive wall wake (LRWAKE) using elegant/pelegant code? Please help.

Re: Multi-particle tracking in presence of long range resistive wall in ultra-low emittance ring

Dear Dr. Borland,
I added USE_DISCONNECT =1 on all the WATCH elements, but it give same error. Please find attached lattice6.lte and error for your comments and correction.

Re: Multi-particle tracking in presence of long range resistive wall in ultra-low emittance ring

Dear Dr. Borland,
I tried to implement but still the problem persist. Please see the lattice6.lte, run6.ele and error showing "Unable to open file run6.wp1006 for writing (SDDS_InitializeOutput)" for your comments and correction.

Multi-particle tracking in presence of long range resistive wall in ultra-low emittance ring

Dear Dr. Borland, I want to study the effect of long range resistive wall on beam motion using multi-particle tracking with Pelegant. In input *.lte file I defined 1536 slices with 1000 electrons in every slice so there are total 1536000 electrons. In *.ele I defined one bunch consist 1000 electrons...
