Hello Maurik,

Apologies for being sloppy on the absolute positions. You are correct that the

dipole field is shifted into global coordinates when being used in HPS.

I just wanted to demonstrate that the unfolding into the remaining three

quadrants was done correctly.

Hello Norman,

Presumably the field is shifted in z (and a little in x) when placed into the SLIC geometry?

A minor thing, but I also presume the -1500 to 1500 axis is z, and -300 to 300 is x? (that makes this a left handed coordinate system, curious)

Best,

Maurik

Hello All,

Here’s a plot of B_y as a function of x and z as unfolded and being used in slic

and org.lcsim. I’ll generate similar plots for the TOSCA files that Stepan sent

around.

I am working on functional fits instead of interpolations to speed up the field

value calculations.
