Picture shown :

Split Compton suppression BGO detector.
Four two inches phototubes, four optically independent BGO segments. Side and back catcher capability.
Thin walls in the vertical junction plan for maximum efficiency and minimum loss.

....... a precise sketch,
Preamplifier included (Y/N),
High voltage (HV) connectors on phototubes (BNC, HV, SHV, Lemo size O, other),
Signal connectors on phototubes (BNC, Lemo size OO),
Quantity of HV or signal connectors per phototube,
Dynode output,
Cables if necessary length ?,

Type of external environment (pressure, moisture, water.....),
Expected detector overall dimensions,

Do not forget to specify the units you use (mm, inch, etc...) Just for a better understanding, an hand sketch is always useful.

ARRAY

If you need a special array of detectors :
Specify individual detectors as above.
Then place each detector in a spherical framework (Radius, theta, phi).
Always consider the incident beam as the reference axis.
Thanks to send us your table of nubers and, if possible, a rough scheme.
