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.
