Below is a draft proposal and charge for an official review of Level 2
convened by Jim Christenson.  Note that only Global and  Cal are part of the
charge unless I hear otherwise.  Jerry and I will be making an agenda next
week with specific speakers.  The general idea will be physicists at the
processor and block diagram level, and engineers for the technical details.
Please pass this along and make travel plans.  I would guess that likely
speakers are:

Overview        Linnemann
Alpha           Martin
MBT             Baden, then Giganti and/or Bard
SLIC,SFO,CIC    Fortner, then Sippach? (Gara is not available)
FIC             Renardy

Global          Moore
Cal             Varelas

This will be iterated and actual times alotted, but I am sure that the folks
listed can expect to speak.  I would like transparencies on the web by 8am
Eastern time Thursday  4 February.

Sufficient progress has been made in defining and designing the Level 2 Trigger
system that it can now be reviewed as is our established practice of setting the
specific implementation of components of the Dzero Upgrade.  We would like you
to help with this important review.  The review is scheduled for Saturday,
February 6, 1999.  This date would allow the trigger folks to carefully consider
the results of the review at the Trigger Workshop in March and would allow some
key members of the Level 2 operation to attend the review.  We imagine that a
day would be devoted to presentations and discussion, followed by a relatively
brief written report.

Review Panel:  Boris Baldin, Amber Boehnlein, Alan Jonckheere, Rick van Kooten,
Dean Schamberger,  Mark Strovink (chair), Gordon Watts, Darien Wood

Date:  Saturday, February 6, 1999

Review Agenda:  To be drafted by the Trigger Project managers Jim Linnemann and 
Jerry Blazey, in consultation with the Chair.

Draft Charge:

Review the Level 2 Trigger project as described in the Technical Design Reports
and report in writing to the Upgrade Project Managers and the Spokespersons. 
This Review will cover Level 2 Global and the Calorimeter Preprocessor, as well
as their components: Alpha processor, Magic Bus Transceiver (MBT), Second Level
Input Computer (SLIC) and Fiber Interface Converter (FIC).  Other Preprocessors
will be dealt with in subsequent specific reviews administered by the Trigger
Manager directly.

The Review should be based on the written TDRs, presentations by the Trigger
group and discussions during the Review.  You should consider whether the design
and implementation of the system is consistent with the physics goals of the
experiment in Run II, including possible expansion of the system to accommodate
STT triggers.  You should explore the system design to determine whether it is
comprehensive and sound.  Does it accomplish the goals efficiently and in a
cost-effective manner?

Please include the following topics in your deliberations:
       Bandwidth capability
       Error detection, recovery
       Event buffering
       Trigger bit hierarchy, relationship to Level 1
       Downloading and verification of same
       Debugging and evaluation of trigger performance
