Charge for the Workshop

For each of the NIU sessions, we would like to have some preparedtalks to cover the following:

1. Schedule of completion of the hardware

2. Test program at the board level (who, where, when?)

3. Test/commissioning of the sub-detector trigger or frameworkprior to commissioning in the D0 environment in the D0 Hall.(who, where, when?)what other resources are needed (serial links, downloads, COOR,clocks, etc.)

4. Commissioning in D0.

What is the sequence, time estimate for the commissioning?How will cosmic ray studies be used?What interactions with other systems are required?Give an estimated schedule for commissioning.

Board Testing

AFE > 8 MCM bench test - AnTS (on cassette in lab 3)

AFE > 12 MCM bench test - AnTs (on cassette in lab 3)

DFE bench test - DTS

Mixing Box bench test - DTS

The AFE testing @ lab3 requires

working cassettes light pulser system w

VTBG Seq/SeqC/VRB/VRBC trigger generation

logic 1553 links PC / bit3

DD


Board Testing cont.

The DFE testing requires input pattern generator

test patterns tracks

output pattern analyzer download link 1553 link PC / Bit3

The MB testing requires input pattern generator

DD


AFE Board Testing

Some AFE production boards will be tested @ lab3 stand

Test with ‘real’ inputs Test with more

realistic grounding and noise environment

Test cryo and bias supply functions

Note: [MCM are tested prior to mounting on AFE]

Bench test requires development of analog input method

Low amplitude charge injection

VTBG System Input conversion

HD connection that can survive 200 boards

FLEX type cable mated to VTBG

DD


DFE Board Testing

Special Test Daughter board produced

High speed “Data Pump” db generates patterns and fake event data, and checks the output of the DFE

Each of the different Daughter board types will require different test firmware/PC software

Mother board, Transition board, and daughter board sets are tested.

DD


MB Board Testing

The ‘Mixing Box Test Board’ serves as input pattern generator and output analyzer

high rate input source provides high speed

and high bandwidth lvds loopback testing

Share PC and test stand with DFE

Bench test requires

Test pattern input board

Test pattern receiver board

Test generation software

Test analysis software

DD


Test/commissioning of the sub-detector

Commissioning in D0.

4. Commissioning in D0.

What is the sequence, time estimate for the commissioning?How will cosmic ray studies be used?What interactions with other systems are required?Give an estimated schedule for commissioning.

DD


Cosmic Ray Trigger

Trigger on CR that penetrates to center of CFT

require MUON on inward track require track through beam

pipe with CFT

Can trigger down to ~0.5GeV in tracker(?)

Trigger elements uScintOctant CFT A-layer-back-

to-back other CFT layers to

fine-tune rate Timing

run at 396-132 live for CFT

window - 80of396ns or 20%

Tests L3 track finding L2 trigger L1 trigger

Similar Trigger forward with FPS & Forward Muon?

DD


‘In Place’ Commissioning

Four Separate Systems can proceed independently

Each of the systems is commissioned in 3 Stages -

same as sub-system commissioning outlined earlier Each stage adds more hardware Each stage requires more software

A 4th stage - CR running - added with no special hardware

NOW Host software is ON-LINE Can start with ‘one crate’ Can finish within one month after last crate

or about 3-4 months total time (whichever is longer)

DD


Overall Software Needs

KISS Applies keep it simple

Have different types of users

technicians engineers physicists

Have different environments

Stand alone bench tests

sub-dectector as part of full detector possible CR running

Have different goals test/fix/maintain

individual boards develop system

expertise test/fix/maintain full

system

DD


Software cont.

Bench Tests traditionally used PC,

bit3 and windows /excel based software

need users (technicians & engineers) to be able to understand and modify software

Full system tests want to run within

full D0 system run Examine’s and

Calib’s with ON-LINE

Partial systems gray area between

bench and full system

in use / development at lab 3

DD


Infrastructure Required

Bench Tests PC Trigger / clock generator Input generator Output capture Group will provide

software / firmware test fixtures procedures

Need - Physicists for system design / data analysis PC based software help

DD


Infrastructure Required

* Need new bodies for these outside of present group

Full system tests trigger generation SCL (clock and control) DAQ Online Group will provide

special trigger generator hardware

test fixtures D0 provides

online system and software examine and calib shells

Need* MC Track generation

software MC Cluster generation

software (for CR) found-tracks to

survey to new trigger-equations

Examine & calib software

help with special firmware

DD


Summary

Hardware will arrive relatively late Much work between production of

hardware and running A lot of support and fixture hardware

needs to be designed and built - Schedules will suffer without needed EE

support.

A lot of support software needs to be written, and shaken out - Schedules will suffer without needed PH

support.
