Spectrometer Ancillary Equipment

Summary information on the ancillary equipment is given below. Manuals, technical specifications and other documents describing the ancillary equipment at the laboratory, are all available in the CNBC work area.

The ancillary equipment listed here can be used with any of the neutron instruments. For information on equipment available to only a subset of instruments, see the pages specific to that instrument (C2, C5, D3, E3, L3, N5 or T3).

Monochromators

A wide selection of monochromators is available to match the monoenergetic characteristics of the scattered beam to the experiment (e.g. Ge, Si, Pg, Cu).

Cryostats

• D1, closed cycle (Displex), 10 to 300 K
• D3, closed cycle (CTI), 12 to 300 K
• H6, 10 cm bore, top load, 4 to 300 K
• H8, 5 cm bore, top load, 1.5 to 300 K
• M2, horizontal field (3 T), top load, 1.5 to 300 K
• M4, vertical field (6 T), 4.0 to 300 K
• M5, vertical field (9 T), 0.3 to 300 K
• Cryostat for biological studies (manipulation of both humidity and temperature)

Furnaces

• FD, cartridge heater based furnace temperature range 300 K to 1000 K vacuum typical 1.0E-2 torr
• F3, radiant heater based furnace temperature range 300 K to 2200 K vacuum typical 1.0E-7 torr

Filters

• Cold beryllium or sapphire (77 K), before the monochromator
• Cold beryllium (77 K), cryostat can be placed between monochromator and specimen or specimen and analyzer
• Pyrolytic graphite can be placed between monochromator and specimen or specimen and analyzer
• NVS, C5 only, before or after sample, 2.37 to 4 Angstroms

Mechanical Devices

• XYZ translation tables
• Kappa Goniometer
• C Cradle
• Eulerian Cradle
• Precision collimating devices to study volumes as small as 0.3 mm × 0.3 mm × 0.3 mm
• Chopper to determine higher order contamination in incident beam

Process and Control

PC based temperature and process control systems for each spectrometer operating as a slave to the spectrometer control computer.
