Germanium Primer
It is impossible to completely describe all the intricacies of the detectors, but this document should answer some basic questions.
Basics
The array has 4 rings of detectors.
- 1 - 5 are at 158 deg
- 6 - 10 are at 134 deg
- 11 - 15 are at 101 deg
- 16 - 20 are at 79 deg
Calibration
- The germaniums are gain-matched in hardware to be 0.5 keV/ch on 8192 ch.
- The doppler-corrected spectra are 1 kev/ch
- The TDC spectra are 0.2 ns/ch (i.e. 1ns = 5ch) on 2048 channels
