Bending magnets

A BEND is a magnet of the dipole type:

      

A MBN dipole

Length = 5 metres
Strength BL = 10.8 Tm
Bmax = 21.6 kGauss


Its purpose is to deviate a beam over an angle theta given by

theta = 0.2997 • BL / p

where p is the beam momentum in GeV/c and BL the bending power in Teslameters. Theta is the angle in radians.

A detailed description of used dipoles can be found in the Magnet bible (EDMS 1062808).

In the SL/EA group many different types of bending magnets are in use. Please find below some data on some of these types.
