Naming conventions
Detector, Ladder, Tray
Names
Detectors, ladders and trays are identified by a simple index N and the
suffices D, L, T. N = 1,2, ..... .
| Type |

The detector number is marked on the detector
itself by the manufactor. |

Detector Position in a Ladder
The position of a detector within a ladder is indicated by a capital letter,
A, B, C, D, E. The position A is the closeset to the electronics.
The oriantation of a detector in the ladder is so that the bias resistors are away from
the electronics.
Ladder Position in a Ladder
The ladder position wthin a tray is counted from 1 to 10.
Ladder Wire Bond Names
The wire bonds between detectors in a ladder are numbered from 0-321. Bond 0 and
bond 321 are the bias ring connections. Bonds 1-320 are the 320 wire bonds between
the strips.
iv-curves
The detectors, ladders and trays are tested during the assembly. In particular i-v curves of the
total detector current are measured. The name of a file starts with the type of measuement (iv) followed
by the name of the detector (or ladder, tray) and the date and time.
The date and time format is:
YYYYMMDD-hhmm
and is a fixed format with
YYYY: year (4 digits), MM: month (2 digits), DD: day (2 digits),
hh: hour (2 digits) and mm: minutes (2 digits).

Continuety Measurements
The file names for continuety measurements are the same as for iv-curves except
that the suffix ivis replaced by cs.
Where are the files
The measurement results are on \\GLAST\home\glast\tracker.
