Re: Momentum aperture in a two energy storage ring
Hi Michael, I solved the problem. I need to reset 's' column in the high energy ring twiss file. The integration function otherwise takes the values ranging from 171.7 to 343.4 m in the high energy ring that giving the factor of '2' difference in Touschek lifetime. After doing that, 's' column in th...

Re: Momentum aperture in a two energy storage ring
Hi Michael, Thank you so much for your reply. Now I am able to get Touschek's lifetime for each ring. I have used the analytical formula (formula attached in the previous post) to calculate the lifetime in each ring. And also I use ELEGANT to calculate the corresponding tLifetime for each ring. The ...

Re: Momentum aperture in a two energy storage ring
Hi Michael, Thank you so much for your reply. It is of great help. But, how to calculate Touschek's lifetime in this case? What is the formula that Elegant does use to calculate Touschek's lifetime? After running the momentum aperture simulation for the whole ring, I separate the momentum aperture f...

Momentum aperture in a two energy storage ring
Hi Michael, I am having trouble to calculate the momentum aperture and Touschek's lifetime in a two-energy storage ring. We have two rings connected through SRF cavities. Low energy ring (150 MeV) and High energy ring (1000 MeV) are connected by SRF cavities which first accelerates the beam and then...

Re: Injection Efficiency
Hi Michael, Using this example I tried the following but unable to get output for each interval. It printout each turns instead of specific turns. &run_setup lattice = SR_1000MeV.lte, use_beamline = SR_cooler, p_central = 293.54100292171, parameters = "%s.param", ! rootname = <rootname> default_orde...

Damped emittance and right time of flight
Hi Michael, What is the right way to set up Synchrotron Radiation and Quantum Excitation effect in a ring? I m trying to estimate equilibrium damped emittance from tracking in a dual-energy storage ring. I am using the following: &alter_elements name=*, type=CSBEND, item=N_KICKS, value=150, allow_mi...

Re: Longitudinal phase space tracking in dual energy storage ring
Hi Michael, Last time you suggested to use "magnify" element to make (x,x')=0 for the longitudinal study. That works. But what if you decided to see the effect of synchrotron radiation? If (x,x')!=0, then particles get lost after few number of passes in the ring. I have attached lattice file and ele...

Longitudinal phase space tracking in dual energy storage ring
Dear All, I have a dual energy storage ring, one ring at lower energy and another at higher energy connected by RF. I tried single particle tracking and found that after certain passes, particle gets lost. However, applying "magnify" element after the RF cavity ( to make transverse co-ordinates zero...

RF cavities set-up for two energy rings
Hi, I am getting trouble with RF cavities set-up in my two energy storage ring lattice file. Line=(Low energy ring(55 MeV), accelerating cavity1, accelerating cavity2, High energy ring(155 MeV), decelerating cavity1, decelerating cavity2) I am using matrices to represent low energy ring and high ene...
