1. A high quality beam has low emittance and low energy dispersion.

2. Vriable emittance thermal control device is one of the focus of the future spacecraft thermal control.

3. The beam emittance and brightness are the important figure of merit for the beam in accelerator.

4. For # the following batch of projects is scheduled: Scheduling, Ordering, Despatch & Receipt, Invoicing version # emittance Advice

5. The solar absorptance changed obviously , while the emittance has little change after irradiation.

6. 8 The influence of the scattering albedo and scattering phase function to the apparent emittance was investigated.

7. The nonlinear space-charge field of a beam is a serious concern for beam emittance growth in particle accelerators.

8. The influence of the scattering albedo and scattering phase function to the apparent emittance was investigated.

9. A laser-ablation ion source is provided for generating a low energy ion beam having low longitudinal and transverse emittance.

10. The LEDs are arranged in close proximity so that a luminous emittance from a emitter area of the LED array is at least 1000 lumens per square centimeter.

11. 23 As a result of infrared correction, curves of relationship between output signal and blackbody radiation were established to convert the original image data value into radiant emittance.
