Image of the week: Precision magnetic field mapping for CERN experiment NA62

In the CERN experiment NA62, low-mass straw-tube tracking-chambers have been designed to operate in vacuum and, in conjunction with precisely mapped magnetic fields, enable the determination of the trajectories of the charged decay products of a 75 GeV/c K+ with high accuracy.  

This week’s image is from this paper on NA62 by John R Fry, Giuseppe Ruggiero and Felix Bergsma.
