1. Quality Control Infrastructure
Use computer controlled instruments
Minimize manual data entry
Keep (complete) electronic record
=> a brief description of our plans
=> you will see most of it during the tour

2. Conceptual Overview WWW MySQL Database Barcode Scanner High Voltage
Gas
System

3. Software Tools The database is mySQL (3.23.54a-3.72)
Hosted on a Linux PC
Apache web server, php scripting language
For web graphics we use jplib
Support for database access from Linux and Windows
Components (a.k.a Server) for our hardware devices including oscilloscope, barcode scanner, gas system, HV system…

10. Module Assembly I We plan to assemble the modules in Smith Lab.
Severe space constraints (Tour)

11. Module Assembly II 4 Assembly Stations Source Scan Station Super Box
(Tube storage in hallway)

12. Tube Handling (Baseline)
Bring box to door
Line up table
Slide tubes onto scan
table
Line up scan table
Slide tubes onto assembly station
Reverse for complete modules

13. Tube Handling (Carrier)
Super Box with tubes
Tube
Carrier
Fixed to wall or floor
In hallway

15. Tube Handling (Carrier)
Scan Table
“J” Carrier
Questions: Is this an acceptable solution?
Can we do something similar for modules?
