MATTER/ANTIMATTER REACTION CHAMBER

	The matter/antimatter reaction chamber (M/ARC) consists of two 
matched bell-shaped cavities which contain and redirect the primary 
reaction. The chamber measures 2.3 meters in height and 2.5 meters in 
diameter. It is constructed from twelve layers of hafnium 6 excelion-infused 
carbonitrium, phase-transition welded under a prsesure of 31,000 
kilopascals. The three outer layers are armored with acros-senite arkenide 
for 10x overpressure protection, as are all interface joints to other pressure-
bearing and energy-carrying parts of the system.
	The equatorial band of the chamber contains the housing for the 
dilithium crystal articulation frame (DCAF). An armored hatch allows access 
to the DCAF for crystal replacement and adjustment. The DCAF consists of 
an EM-isolated cradle to hold approximately 1200 cmì of dilithium crystal, 
plus two redundant sets of three-axis crystal orientation linkages. The 
crystal must be manipulated with six degrees of freedom to achieve the 
proper angles and depths for reaction mediation.
	Connecting the equatorial band to the upper and lower halves of the 
chamber are twenty-four structural pins. These pins are hafnium 8 
molyferrenite and are reinforced in tension, compression, and torsion, and 
are continuous with the engine structural integrity field. Running along the 
center of the equatorial band are two layers of diffused transparent tritanium 
borocarbonate for reaction energy visual monitoring.  Æ
