| Bit Error Rates |
The qualitiy of the links in the L1Cal2B system is quantified by their bit
error rates. A tolerable BER for a particular link is given by the
conditions of:
1) no errors that compromise DØ data taking
2) less than one data error per eight hours of normal operation
of that link. Trouble shooting of data errors below this rate will
likely be neglected
until after the shutdown or perhaps even tolerated indefinitely.

|
|
| ADF Crates (80 ADFs total) |
|
Canned data that repeats set patterns every turn to exercise
trigger algorithms in a pre-determined fashion.
|
|
|
|
Pseudo-random data.
|
|
|
|
Real data from N splitter channels (specify N!)
|
|
|
|
A mixture: e.g. real data for N splitter channels, canned data
for remainder of detector.
|
|
|
| TAB/GAB Crate |
|
Operation with 8 TABs + 1 GAB in final crate
|
|
Mulhearn |
| TAB Operations |
|
Receiving data from all ADFs and setting parity, sync, and
BC number status bits.
|
|
Mulhearn |
|
Running the sliding windows alogirithm on all ADF data
|
|
Mulhearn |
| GAB Operations + And/Or Terms |
|
A diagnostic and/or term that fires every BC10
|
|
Mulhearn |
|
An and/or term that fires every time a splitter channel
is above threshold. This, along with
2B-to-precision correspondence plot generated from the
resulting data, represents the PRIMARY deliverable for the
operating system prior to the shutdown.

Driving both ADF and TAB/GAB from tbilisi using TCC or expert
direct access to VME.
|
|
Mulhearn/Laurens |
| Readout Crate |

GAB.
|
|
Mulhearn |
|

Notes |
| Program L1Cal from TCC/COOR |
|
Stable Operation == being able to program system from COOR as if
it were installed
(even though there are no signals on the sidewalk to trigger on)
|
|
|
|
Implement L1Cal protocol at COOR
|

|
mostly done |
|
TCC control of TAB/GAB

Mulhearn/Laurens |
|
Firmware Configuration -
Need one-click configuration of all firmware, and constants
|
|
Mulhearn/Laurens |
|
Define/implement initialization procedure
|
|
Mulhearn/Laurens |
| Triggers |
|
Modify global trigger configuration to include sidewalk crates.
|
01-Nov |
Lammers |
|
Design L1Cal2b trigger to be included in global trigger list for
operational period. This would be some kind of EM
trigger based on our 4 splitter towers, as well as some kind of
jet trigger based on canned ADF test input data.
