GLAST LAT Project 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 4.1.9 - Integration and Test 11 Aug 04 Face to Face Meeting 6

GLAST LAT Project Roadmap Roadmap • LAT-TD-03075 Document written and agreed to February 2004 • Status of required elements follows • § 7 – Bonus items are not addressed • § 8 – Subsystem support is never ending 4.1.9 - Integration and Test 11 Aug 04 Face to Face Meeting 13

GLAST LAT Project 6.1 – – GASU GASU 6.1 � 6.1.1 – Trigger API � 6.1.2 – ACD script migration � 6.1.3 – EBF (now called LDF) package update • New request � ACD software counters 4.1.9 - Integration and Test 11 Aug 04 Face to Face Meeting 14

GLAST LAT Project 6.2 – – Hardware monitoring system Hardware monitoring system 6.2 • Development started by ELX for Test-bed needs FSW is developing a housekeeping telemetry server • � Released. Online needs training. • HskSvr usage will fit seamlessly into ELX monitor • Online is adding – Alarming – Alerting – Archiving – Trending LATTE 4.x preliminary version running in B33 for EM2. LATTE 4.x preliminary version running in B33 for EM2. 4.1.9 - Integration and Test 11 Aug 04 Face to Face Meeting 15

GLAST LAT Project 6.4 – – Event Event prescaling prescaling in in VxWorks VxWorks 6.4 • Needed to manage nominal or higher trigger rate testing � Completed However, new request: • Simple event data filtering – Requires FSW support � Delivery 15 August, 2004 4.1.9 - Integration and Test 11 Aug 04 Face to Face Meeting 16

GLAST LAT Project 6.5 – – Subsystem scripts Subsystem scripts 6.5 • Official deliveries needed prior to V&V phase • None yet received • Development snapshots stored in CVS • Online gaining experience with these snapshots • E2E scripts in progress (Lester, trigger group) 4.1.9 - Integration and Test 11 Aug 04 Face to Face Meeting 17

GLAST LAT Project 6.6 – – Security against unauthorized software changes Security against unauthorized software changes 6.6 • 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 Available in LATTE 4.x and is being exercised in B33 during EM2 testing. Available in LATTE 4.x and is being exercised in B33 during EM2 testing. 4.1.9 - Integration and Test 11 Aug 04 Face to Face Meeting 18

GLAST LAT Project 6.7 – – Security against operator complacency Security against operator complacency 6.7 � Permission scheme set up � Operator authentication � Certain features are enabled or disabled according to operator permission level � Normally disabled for backward compatibility (e.g. during commissioning) � Core system modified to use it – Test scripts must use it for it to be effective • Operators must sign off on input parameters – Test scripts must use it for it to be effective. In Progress 4.1.9 - Integration and Test 11 Aug 04 Face to Face Meeting 19

GLAST LAT Project 6.13 – – Validation & verification (1) Validation & verification (1) 6.13 • 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 4.1.9 - Integration and Test 11 Aug 04 Face to Face Meeting 24
