FASER Magnet

Magnet Design

  • The details of the FASER dipole magnet design can be seen in the design report here.
  • A very nice seminar on the FASER magnets from Pierre can be seen here.

Magnet orientation

  • The current plan is for the magnets to be aligned such that a positive charged particle entering FASER will bend downwards (TBC after installation!)

Field Measurements

Magnet 1 (1m long)

  • A quick look at the field map in FASER_filled_cylinder shows that this contains 29 measurement points in the transverse (x-y) plane as seen here, and for each of these a very fine set of measurements in the longitudinal direction (z) is taken. Plots of the 3 measured field components at each point, as a function of z can be seen in the following: Bx, By, Bz.

  • We need to decide where this magnet goes in the spectrometer (front or back)

Magnet 2 (1m long)

Magnet 3 (1.5m long)
