Room 104 Clean Room Configuration Room 104 Clean Room Configuration

Draft Procedure available in LATDOCS. (LAT-DS-03281)
Some graphics improvements in work.
Space in room 104 is tight with limited parallel processing

space available. – Only enough space for the LAT integration stand or the LAT Mock-up stand at one time. – Metrology bay must be moved out of room for ACD and X LAT plate installation. – LAT integration stand must be moved if rework of ACD required. – Unused MGSE must be stored outside room 104

6.6 6.6 – – Security against unauthorized software changes Security against unauthorized software changes

In the I&T testing phase (not commissioning phase), protection

is needed against on-the-fly editing of code and configurations as the changes can’t reliably be tracked Run reports indicate mismatches with released files Kiosk mode Read-only source files

6.13 6.13 – – Validation & verification (1) Validation & verification (1)

Subsystem test-stands

– Many instances ( ~40 ) – Many hours of operation – Many people involved, each with a different approach

EM-1 and EM-2 tests with mini-tower

– More complete with hand-off of persistent data to SVAC – But, less seat time and consequently less practiced

Full tower testing (no detectors)
Test-bed testing

– In progress in ELX with LATTE 4.x – Hardware not yet fully functional

Standalone mode testing

– Useful for developing code not requiring hardware interaction

SLIDE 25

GLAST LAT Project 4.1.9 - Integration and Test 11 Aug 04 Face to Face Meeting 25

6.13 6.13 – – Validation & verification (2) Validation & verification (2)

Limited unit testing of core functions
Will exercise system in not often explored corners of phase

space – Bad data – High data rate – Large data sizes

Will induce errors in major blocks to verify graceful behaviour

– Induced exceptions

Will generate a matrix of features with checked-off test criteria

Confidence will improve with more testing However, we need to define an end point

RFA By To Answer STATUS

Please trace responsibility for every pass/fail test within I&T. Which department performs and evaluates each test? This is very important because these pass/fail tests determine whether we can proceed to the next stage of the build. The LAT schedule Steve Ritz Eduardo do Couto e Silva After discussions with SE SVAC realized that PASS/FAIL nomenclature used for SVAC tests are not the correct terminology to use. All Pass/Fail tests are the responsibility of IFCT which performs all of these tests. The scripts that drive these tests have P IN PROGRESS slide 39. Evaluate the processing times for each step and end to

end. Match the computing resources and personnel to the expected

data volume by day. Steve Ritz Eduardo do Couto e Silva ned pipeline to finish that. Data volume captured in LAT-MD-00575 IN PROGRESS slide 39. Please describe the calibration validation process. After each calibration is performed, the resulting constants set must be validated (ranges, changes from previous, etc.), and the calibration set must be flagged as good or bad. Who is respo Steve Ritz Eduardo do Couto e Silva SVAC is responsible for all that and how this is going to be implemented will be described in LAT- MD-00575 IN PROGRESS You should examine what elements of the pipeline and analysis

peration will be stressed by a potentially rapidly changing code
environment. For example, is it possible to rerun particular steps in

the pipeline if a small version change is made in that st Richard Dubois Eduardo do Couto e Silva Under discussion IN PROGRESS What is the configuration control scheme envisaged for ensuring that the SVAC etc scripts etc that are run in the pipeline are in fact the

nes agreed to. Will the agreed tags be checked out of cvs and

made read-only for use by the pipeline? Richard Dubois Eduardo do Couto e Silva Agreed we communciate with SAS via CVS, but we need to make sure we have a plan to handle updates in the future IN PROGRESS 1) Create mechanism and schedule for scripts to parse and decommutate schema, snapshot, and online report. 2) Strengthen and formalize communication between online and offline with regard to command state. 3) Define and create deliverables for Towers A Eric Grove Eduardo do Couto e Silva / Ric Claus SVAC pieces will be hnadled via LAT-MD_00575 and Eric has alredy a copy for review.

» Issue: SAS not fully convinced of importance of TOT. SVAC needs it for the first tower tests

– LDF Parser

» Issue: SAS and Online need to finalize their interface since SVAC needs data files from SAS for EM2

– Analysis Ntuples

» Issue: SAS and SVAC have not agreed where to store detector information (e.g. trigger). Need resolution ASAP to support EM2 testing

– Geometry

» Issue: SVAC needs traceability of geometry information that has lowest priority in SAS work

Cal EM-2 Observations

The following items were observed during the receiving inspection and installation of the EM2 Calorimeter.

Connector covers missing on 2 connector ports. J1 on TPS and JS1
n TEM.
Misaligned mate found on CAL to TEM connector. One screw and jack

post found stripped contributing to the awkward mate.

No shock indicator on outside or inside of shipping container.
CAL unit found a little out of square in relation to the shipping
container. This is only a concern because there is no shock indicator.
No pressure on purge lid gauge. A vacuum was discovered while

depressing the red purge button. Our procedure, LAT-PS-03027, requires above 5 psi. Should we consider revising this number? Should the container by pressurized? We’ve never received a Calorimeter with the gauge indicating positive pressure.

Debris found on top of the calorimeter.
1X1 base plate interferes with NRL calorimeter lifting corner brackets.

Safety First

– Personnel Safety – System Safety

Communication is key to success

– Use visuals whenever possible; flow charts, status, Quality metrics – Liberal use of pagers and cell phone – Need subsystem POC and alternate for off hour anomaly resolution.

I&T Engineering Responsibility

– Interpret LAT Engineering requirements from drawings and specs to I&T procedures for execution by Techs – Provide ongoing support for troubleshooting and problem resolution.

Don’t do anything for the first time on flight hardware.
Don’t proceed unless everyone has a clear understanding of the task.

Minimize risk.

I&T Operating Plan I&T Operating Plan

Plan for 2 shift operation

– Minimum staff will be 1 Lead Technician, 2 Technicians and a Test Conductor or Test Director on shift (4 people per shift).

Shifts will run 7:00am-3:30pm and 3:00pm-11:30pm

– Daily morning meeting at 7:00am – Half hour overlap will facilitate a daily “hand-off” meeting at 3:00pm. Shift log will be used for documenting hand-off. – Shift hand-off between 2nd shift and the following day will be accomplished via shift log.

Baseline plan is 2-8hr shifts/5 days a week.

– Extended shifts and/or Saturdays will be used to maintain schedule as required.

Work has been scheduled on Friday after Thanksgiving and

through the Christmas shutdown.

Summary and Conclusion Summary and Conclusion

We are closing in on readiness for flight hardware integration.
The resources are in place.
Documentation and Planning are near term focus.
Training is on-going on EM hardware.
MGSE is arriving “just in time”.
Successful integration phase will depend on close
