Quality Control Infrastructure

1
Quality Control Infrastructure

• Use computer controlled instruments
• Minimize manual data entry
• Keep (complete) electronic record
• gt a brief description of our plans
• gt you will see most of it during the tour

MySQL
Database
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

Questions Is this an acceptable solution? Can
we do something similar for modules?
