| The
tracks of charged particles in the detector and hence event
display are curved due to the presence of the strong applied
magnetic field inside the detector. Oppositely charged moving
particles curve in different directions under the influence
of a magnetic field. Also the radius of curvature of the particle
track depends on the momentum of the particle. Therefore we
can determine the charge and momentum of a particular particle
by simply looking at the curvature of of its path. |

| A
much better way of displaying particle events is in three dimensions,
where it is possible to get the entire picture of the interactions
taking place. To do this we have used a java applet that can run within
a web page. |
| In the pages
that follow several interesting events from our data are displayed
which can be observed from all directions and zoomed in on using the
scroll bars on the bottom and to the right of the display. It is also
possible to alter the strength of the magnetic field within the detector
to see the effect it has on the curvature of the particle tracks.
You can view information about a particular particle,such as momentum
and velocity, by clicking on the particle track. Calormeter hits are
shown as red lines outside of the central detector with the length
of the lines proportional to the energy absorbed. |
