Setting of bmp_noise and force specific position in &correct
Posted: 23 Jul 2019, 15:30
Hello,
I would like to use the &correct command with bpm noise. The BPMs are assumed to have a noise of 50 microns with gaussian distribution and the cutoff should be 3 sigmas, both in both planes.
I tried to use
bpm_noise[0] = 50e-6, 50e-6
bpm_noise_cutoff[0] = 3,3
bpm_noise_distribution[0] = "gaussian", "gaussian"
I'm wondering if this is the correct way to use it as I don't see that the correction is affected at all by this setting.
Could you explain how the index in square brackets has to be set? I thought it should be 2 as I'm setting values in two planes, but it only works when I'm setting it to 0.
Furthermore, is there a way in the &correct command to force a specific position at some elements even with the cost that the beam is more offset at other positions? I'm thinking about a bump, where an offset of for example 1mm should be achieved within a specific region. The goal is to really have this offset of 1mm in this region, even if the payoff is that the beam takes longer to return to (0,0) after the bump.
Thank you very much for your help!
Best,
Lea
