#	Part	Qty	What it does
1	NaI(Tl) Scintillation Crystal	1×	Single thallium-doped sodium iodide crystal, ~9 mm thick, that flashes light when struck by a gamma photon.
2	Optical Light Guide	1×	Glass coupling layer spreading scintillation light across the photomultiplier faces.
3	Photomultiplier Array 3 parts	1×	Hexagonally packed array of photomultiplier tubes reading the light and encoding the event position.
4	Preamplifier Board	1×	Charge-sensitive preamps conditioning each tube signal before digitisation.
5	Head Lead Shielding	1×	Lead jacket
6	Mu-metal Shield	1×	Magnetic shield protecting the photomultipliers from the Earth field and gantry motors.
