The main beam elements ramp with the momentum,
|
|
|
|
but up until now, the corrector elements have been
|
|
|
|
operated DC
|
|
|
|
Ž |
Beam can “wander” by up to a few cm’s during ramp.
|

Ramping control cards were installed during the
|
|
|
|
shutdown.
|
|
|
• |
Closure control program almost ready. Still needs to
|
|
|
|
be tested.
|
|
|

Correctors not powerful enough to steer the beam all
|
|
|
the way through the cycle. Still,
should help.
