High-durability single-crystal phosphor screen revolutionizes conventional imaging

The direct bonding type phosphor screen that can be selected as an option is a single-crystal phosphor screen with extremely high X-ray durability.

It suppresses the destruction of a phosphor screen by X-rays and realizes stable imaging and measurement for a long period of time.

Synchrotron radiation white x-ray phosphor screen

No destruction occurs even if synchrotron radiation white X-ray is incident for a long time.

Measurement conditions

Beam line SPring-8 BL28B2
X-ray energy White
Attenuator Air (9 m), Aluminum (0.034 mm), Be window (1 mm thick on the beam line side + 0.5 mm thick on the detector side)
Beam size 3×3 mm2
Detector

Glue bonding type: AA40 (f = 50 mm) + ORCA-Flash2.8 (f = 35 mm) 

Direct bonding type: AA40 (f = 50 mm) + ORCA-Flash4.0 (f = 50 mm) 

Pixel resolution Glue bonding type: 5.1 μm / pixel, Direct bonding type: 6.5 μm / pixel
Scintillator LuAG (Thickness: Glue bonding type about 20 μm, Direct bonding type about 20 μm) *
* AA40 is used for durability evaluation. The single-crystal phosphor screen is not recommended for use with AA40.
