The Time Line Generator (TLG) sequences all
accelerator
|
|
|
|
operations.
|
|
|
| • |
Traditionally, each sequence (“module”) is
independent,
|
|
|
including any necessary Booster prepulses.
|
|
|
| • |
This wasn’t really compatible with the goal of
getting the
|
|
|
|
maximum possible beam out of the Booster.
|
|
|
| • |
In the new scheme:
|
|
|
|
– |
Standalone sequences are placed in the time line,
with necessary
|
|
|
prepulses
|
|
|
|
– |
MiniBooNE pulses are “trailer-hitched” to the end of
these to achieve a
|
|
specified average repetition rate, subject to an
overall total rate.
|
|
|
|
– |
If there aren’t enough modules to trailer-hitch to,
new modules will be
|
|
|
built (still working the bugs out of this one).
