Incident wavelength:	0.25 - 6.5Å
Momentum transfer:	The minimum achievable value is 0.25Å-1, but this value increases as backgrounds increase.
	The maximum value at which oscillations in the structure factor may be observed depends on the degree of short range order in the sample, but values in the range 30 - 50Å-1 are typical.
Beam:	S7
Moderator:	100K CH4 (see section 4.6)
Sample position:	10m from moderator (L1)
Beam Size:	40mm high, 20mm wide, reducible by apertures before the sample (see section 3.4)
Count rate:	5x103 (5°) - 7x104(150°)
Sample environment:	The sample tank is smaller than the ISIS standard (see section 3.1)
Data acquisition:	Vaxstation 3200 (see section 4.2)
