Gamma-Ray Detectors at the Target Position
Description
Recoil-Gamma studies can be performed with ten Germanium detectors from the
ANL-Notre Dame gamma-ray detector facility. They get installed in a frame
designed to surround a small, thin-walled aluminum target chamber. A dedicated
set of electronics has been purchased for this array to expedite the setup of
the detectors at the FMA. Although this is the standard gamma-ray array for use
at the FMA, a larger array called AYEball
was constructed and used between August and December, 1996. Future plans
include the installation of GAMMASPHERE
at the FMA at the end of 1997.

Installing the ANL-ND Array
- contact Robert Janssens. Moving the detectors and cabling takes 1
day. Expect a few days for the whole process.
