Question about CSR

[laxmisubramanyam]

Hi,

Sorry for bothering you again. But I reached to a point where test of CSR becomes essential and I am looking for some clarification about the effecient use of CSR. I have noticed that two methods are used in the examples of using CSR.

The first method is (used in Tutorial 5)

csr = CSR(n_bin=300, m_bin=5, sigma_min=0.2e-6)

and the second method is (used in csr_ex.py)

car = CSR()
csr.traj_step = 0.0002
csr.apply_step = 0.0002

What is the different between these two methods ? Is there any documentation about these two approaches ?

Also, what are the arguments for the default CSR() ?

Thank you.

Best regards,
Laxmi

Hi @ZeugAusHH,

thanks for brining it to the discussion forum ( may be discussion will accelerate here !! ).

I made simulation of electron beam compressor using chicane. Later, I tried to see how CSR affects the electron beam phase-space. However, I didn't see any noticeable difference with and without CSR. This is strange to me. I would like to know if I am including the CSR correctly or not.

Any help will be very appreciable.

Thanks
