COMPUTER SYSTEM HARDWARE AND SOFTWARE

	Data acquisition: Pentium 4 (3.4 GHz, 1GB RAM) running WindowsXP and Omnic Atlus 7.3. For data transfer, it has a 3.5” floppy drive, a CD-R/W drive and an Ethernet connection. transfer
	Data analysis: Pentium 3 computer (836MHz, 512MB RAM) running Windows XP and Omnic/Atlus 7.3.
	Laser Jet 5P printer

OPTICAL CONFIGURATION

Total Angular Acceptance: 45H x 45V mrad.
Mirror: Water-cooled silicon carbide beam extraction; beam is steered and focused by a combination of ellipsoidal and planar mirrors to provide a 1:1 image of the source. Beam passes through a wedged diamond window and continues through rough vacuum and then through either KBr or polyethylene window into the nitrogen-purged instrumentation listed above.
