This special liquid scintillator is formulated specifically
for encapsulation in capillaries for imaging with fast neutrons.
Its important properties are . . .
|
- Very high light output
- High refractive index
- Deuterated to 98 atom%
|
- High flash point
- Low chemical toxicity
- Biodegradable

For good light-piping in capillaries, high refractive index is
critical.
Among the several liquid scintillator solvents traditionally
known for their high refractive indices, most are chemically
and photochemically unstable and consequently darken over a
period of a few months if exposed to air or UV light for even
relatively short times.
Hence the components of EJ-399-05D were selected to provide an
outstanding combination of high scintillation efficiency, high
refractive index and excellent chemical stability in order to
endure the often complicated handling associated with
encapsulating liquids in capillary arrays.

EJ-399-05D additionally has a low vapor pressure making it
suitable for using vacuum techniques when loading capillaries.
Its high flash point and low chemical toxicity make it a
relatively safe liquid to handle.
It is always advisable, however, to exercise reasonable caution
when handling organic solvents with regard to personal contact
and breathing.
