Detailed Description

The BFieldComponentQuad class.

This class represents a magnetic field map from quadrupole magnets QC[1/2]*. Only the field from QC[1/2]* inside beam pipes is described. Leak field inside the beam pipe from the quadruple magnet on the other beam line is also included, however, leak field outside both beam pipe are not described. Therefore, we should turn on this field component only when we use TouschekTURTLEReader and Synchrotron radiation study, which needs accurate propagation of beam particles. Field strength are calculated from the magnet parameters (K0,K1,SK0,SK1) used in accelerator simulation. These parameters are provided for each 4cm slice in the beam direction.
