## CTT Installation Plan

- Current status
- General plan
- Power supplies + permits
- Basic installation + checking procedures

- Stefan Grünendahl

- Installation Review 2005-10-25

## Why upgrade?

- The existing CTT track finder (DFEA) performance is limited by logic resources in the Field Programmable Gate Arrays (FPGAs)
- Xilinx Virtex FPGAs circa 1999, 600k gates
- Track equations use 'doublet' groups of fibers
- More logic resources are now available
- Virtex-II FPGAs are 10x larger, faster, lower power
- Higher resolution track equations use 'singlet' fibers
- Improved efficiency at higher luminosity
- Better fake track rejection
- DFEA2 board design done at Boston University

## CTT System Overview

- Stefan Grünendahl

- Installation Review 2005-10-25

##  Status at FNAL

- Crates and boards in hand; new l1CalTrack cables terminated and DC-checked
- Power supplies and permit for parallel chain in place; need inspection after full crate installation to get permit for full system
- Installation location surveyed, basic procedure agreed upon
- 8 weeks for system and connections testing and repair (+ 8 weeks for physics commissioning)
- Doublet firmware shown to identically reproduce old system
- Singlet firmware: running in DFEA2s; no eff.known yet
- Control and monitoring software in place; first version exercised with parallel chain; full EPICS version under test now

## New Subrack and Backplane

- Improvements
- No more transition boards
- All cables pass through the backplane

- Stefan Grünendahl

- Installation Review 2005-10-25

## LVDS Cable Rerouting

- Low voltage differential signal cables
- 5 differential pairs
- 1.7 Gigabits per second
- Cable tunnels will be installed in PC04 to allow the cables to reach the rear of PC03 and the DFEA2 crates
- Spare cables will be on hand (10%)

- Stefan Grünendahl

## Muon and CalTrk Cables

- 80 existing coaxial cables go to L1muon
- Adding 80 cables for L1caltrk
- New support bracket has been engineered to support the additional weight

- Stefan Grünendahl

- Installation Review 2005-10-25

## Low Voltage Power Supplies

- Our low voltage, high current supplies had problems with remote sense operation
- No redundancy: failure of a single supply means we lose a subrack
- Significant voltage drop even on thick cables
- Supplies must be located near the subrack
- Poor location with marginal cooling
- Half of the backplane was used for bus bars

- Stefan Grünendahl

- Installation Review 2005-10-25

## Distributed Power Architecture

- 48VDC bulk supplies
- Parallel operation, N+1 redundancy
- Hot swap
- Excellent low voltage regulation on the boards using DC-DC converters
- Low EMI
- 36-72V input range
- Forget about remote sensing!
- No thick “welding cables”
- No bus bars on the backplane
- Logic voltages keep dropping: 1.5V, 1.2V, 1.0V...

## Installation Details

_***Hardware Install & Commission: 8 + 8 weeks (no beam + some beam)***_
- Check L1CalTrack cables using old DFEA system
-  Install boards:
- remove DFEA crates; replace baffle above Mixer with version with cable tunnels; retract Mixer-DFEA cables
- Install DFEA2 crates; connect 48V; connect L1Muon and L1CalTrack cables to pigtails; connect Mixer-DFEA2 cables at backplane
-  Debug Inputs: check clock/sync/parity status of DFEA2 using DFEA2 status reporting
-  Verify Outputs:
- check clock/sync/parity of CTOC/STSX/STOV/L1Muon/L1CalTrack inputs
- Check trigger functionality using test vectors and DAQmon + CTT_examine
-  Detailed study of Triggers: needs beam
- L1: verify doublet firmware CTT And/Or rates are the same as before shutdown, using AOTmon; verify L1Muon outputs using L1Muon tools (e.g. TTK(1,10) version constructed by L1muon); ditto for L1CalTrack (using L1muon tools)
- L2: Verify L2 outputs using STT examine and L2CTT/L2PS ‘GM trigger examine’
- L3: verify track triggers using GM examine; RECO outputs
