Module Transmission Testing:
Beginning 10/15/01 we will be doing transmission tests only on modules that
have 2 “bad” fibers already observed in their module maps or modules that we
suspect have been damaged in handling. Module maps must be reviewed before
scintillators are place on the steel.
Module transmission test results:
Module 1
Module 2
Module 3
Module 4
Module 5
Module 6
Module 7

4. Light Injection Cable checkout:
The following two procedures must be accomplished as part of the light leak
checkout procedure. These are done after the clear fiber cables are installed on
both sides of the scintillator module. Fiber 1 position is near the small dowel .
Part 1:
Shine a flashlight down one end of the clear fiber. Check for light on the cable
attached to the far side of the module. The light should start at the small
dowel pin-hole and be continuous across the connector for 20 (CIT module)
or 28 (UMN modules) fibers. Broken fibers will appear dark. If the first fiber
is dark, you should expect the first fiber in test 2 to be dark also. If light shines
beyond 20 for CIT or 28 fibers for UMN, contact the physicist shift leader.
Part 2:
Slide the special black out connector and rubber band over one end of the clear
fiber. Make sure the small dowel hole on the cable and the black out connector
face each other. Shine light on the hole in the black out connector. Light should
appear in the fiber 1 position on the far end of the cable. If the light does not
appear anywhere and fiber one was dark in test one, then you should expect to
find that fiber one is broken. Have a physicist shift leader check the module map.
If the light appears in some position other than position 1, either a clear fiber
cable is mounted backwards or one of the cables has not been built correctly.
Contact the physicist shift leader.
