AFE II/TriP UpgradeWBS 1.2.8

We are proposing an upgrade to the Central Fiber Tracker (CFT) readout & triggering system

Maintain tracking capability in light of cancellation of silicon upgrade, particularly at increased luminosity

considerably improved noise performance – lower thresholds, enhance triggering, efficiency

z-information from timing New Analog Front-End Boards (AFE II) and trigger (TriP)

chip First version TriP chip submitted with SVX4 Designed, tested by Fermilab (PPD, Yarema) Was major success out of the box First full AFE II prototype being laid out now, expect back by

end CY03 System represents major simplification, performance

upgrade Exploiting considerable in-house experience – personnel,

depth of technical knowledge TPC = $2.2M (includes 50% total contingency)

M&S cost estimate based on detailed past experience see talk by Bross

AFE II/TriP Decision Process

Project funding request ($2.2M) includes both salaries and M&S for production only; does not contain either salaries or M&S for R&D

Has been coming from operating funds (e.g., TriP work & testing)

Agreement with Laboratory that this will continue Before fully supporting the pursuit of this sub-

project, we first must convince ourselves that it will provide the experiment with sufficient gains to justify the considerable effort & potential interruptions to data-taking, and that the scheme will work as advertised

Given the time scales (summer ’05 completion), answering these questions must be given sufficient priority during the next few months…and without allowing operations to falter

DZero Run IIb RevNov 05 ‘035 Kotcher

AFE II/TriP Decision Process

The following must be completed before production funds will be released:

Continuation/completion of simulations TriP resubmission

Abder is starting AFE II prototype layout, fabrication & testing

Arrangements to free John A. up to pursue this for next few months being finalized now

Operations will be covered Fabrication and testing must immediately follow

DZero Internal Review, followed by a Laboratory Review, if warranted

DZero Run IIb RevNov 05 ‘036 Kotcher

AFE II/TriP Decision Process

The DZero Review will be a critical one Among the things they will be asked to look over:

Technical gains & feasibility Physics benefits Realism of schedule Long-term commitment of personnel Credibility of installation and commissioning plan, and its

impact on acquisition of physics quality data A major consideration

Will be asked to provide an overall recommendation, submitted to Spokes, PM

If justification is there, and the DZero Internal Review Committee recommends moving forward, would like to hold the Laboratory Review no later than April ’04

Targeting summer ’05 completion (installation during summer shutdown), which is still tight
