Goals
Ensure data integrity at the level of 1014 - 1015, i.e allow for loss of 1 bit in 1014 - 1015 bits transferred
Provide adequate operating margin for device Ensure adequate diagnostics tools and controls Exercise control logic Exercise Data Acquisition and filtering scheme Exercise offline software
Timeline
Commission read out electronics in phases “on the bench” without detectors attached
Integrate final components as soon as available Read out small scale setup in final configuration Enlarge scope of read out
Dec 7, 1999 D0 Dir Review Inst/Com
Current Status
Complete read out system installed in cleanroom in LabC Final version of all read out components, except Interface
Board System run in checksum mode in Level 3 node
» SVX chips downloaded to read out set data value
» All channels read out; data constant
» Calculate checksum (sum of all bits) in VBD
» Data transferred to L3 node; checksum compared
» If checksum different: read in and analyze even

A) Ran with multiple VME Read out Buffer (VRB) boards, without low mass cable and long transmission line, with direct regeneration of signals at hdi, 3-chip hdi’s only
System equivalent of ~22,000 channels
Data transfer on VME at ~ 12 Mbytes/s
Very low noise on data transfer backplane Proper handshaking between read out elements Data integrity > 1013
(~ 1 non-fatal error every ~30 minutes)
B) Ran with single chain (hdi) in close to final configuration, including low mass cable, 30’ 3M/50 conductor cable. Optimized impedance matching for data and control lines on sending and receiving ends
Successfully operated all hdi types Mapped out operating margin for all hdi types Data integrity > 1013 for all hdi types with
comfortable operating margin
C) Written raw data to disk, unpacked and analyzed “offline” within L3 framework and online monitoring program (Examine)

March 15/00:
» Hook up of full H-disk, 48 detectors, 36864 channels; exercise all components
April 1/00:
» Hook up barrel, 72 detectors April 15/00:
» Hook up barrel and F disk, 96 detectors (~10%) May 1/00:
» 15 more detector assemblies to go (5 barrel/disk, 6 F disks, 1+3 H disks)
» one week for read out and debugging per assembly
» Done Aug 15/00
» Note, doubling the time per assembly (23 assemblies) would give completion date of Oct 7/00. Still adequate (7 H disk assemblies can go last)
Timeline
So far discussed development on small scale system (12 ladders) and commissioning of read out system. Move to full subsystem in March 00.
No assembly (barrel or disk) leaves the silicon facility without having been read out.

Barrel and disk hookup at DAB
Hookup of cooling system immediately Run coolant above dewpoint, so no damage to detectors.
Procedure verified at silicon facility Starting 9/26/00, 5 weeks allocated for check out of silicon
detector 1.5 weeks allocated for cabling each detector end.
Note, read out has HDI-enable line, therefore, system can be fully powered at hookup time, thus instant hdi checkout. Procedure should be developed at silicon facility during full barrel/disk tests
Complete Barrel and F disk hookup in 3 weeks.
» Assuming 7days/week, 12hrs/day, this gives ~20 mins of debugging time per hdi
Two additional weeks for debugging complete barrel and F disk assembly. Hookup of H disks in parallel.

Summary
Read out system will be verified continuously. Current level of data integrity for single hdi would be adequate.
Partial barrel with cosmic ray data taking first step to final system configuration
All system components will be exercised at the silicon facility and procedures developed for DAB hookup and commissioning
Many DAQ components exist already in stand alone form,
but are not integrated. All full assemblies will have been read out at the silicon
facility before installation. Development of procedures at facility crucial.
Schedule is tight but feasible
