# MNP17

The MNP17 magnet has a gap of

high,

wide and

long.
The maximum current (

) gives a field of

.
You can control it freely from the EBCR control room, not from the T9 one, including its polarity.

- Magnet in storage:

# MDX

0.51 T.m for a yoke length of 40 cm i.e. field strength of 1.275 Tesla.

# Deflection

Radius of orbit in magnetic field:

E.g. the MNP17 magnet has a field, of , so for a particle with elementary charge, , and a momenta, of ,

The aperture of the MNP17 magnet is long, so a particle will exit the field well before entering an orbit. The angle of deflection will be given by,

For a particle, the deflection angle is around . To find the linear displacement of the particle from the point it exits the magnet, over a distance of, say, ,

There is also a displacement in the magnetic field of,

giving a total displacement of . Repeating this at gives

## Approximation

Since

, and ignoring the displacement in the field; we can approximate the deflection by

at , or at ;
