Pelegant and elegant give different results
Posted: 07 May 2019, 08:05
Hi Michael,
I had a linac simulation which compresses 10pC charge, 1.5ps bunch to only about 2fs in two-stage compression. The beam is accelearted from 100 MeV to 3GeV. I have both space charge and CSR on. Using elegant and Pelegant I got different beam phase space. My elegant version is 34.4.1( Aug 17 2018) on centOS 7 (compiled from source) and I ran 8 cores with Pelegant. I also checked on a Windows machine where I used Pelegant with 4 cores. The difference still showed up.
I attached the phase space and current profile for these two cases.
Do you have any idea where this difference might come from?
Thanks
Qin
