	To reduce the beam loss in the high current linac, beam transverse emittance is a key value which has to be characterized. At Institute of High Energy Physics (IHEP) in Beijing the C-ADS project has started beam commissioning. A newly developed double-slit emittance meter (DEM) for pulsed proton beam from the (RFQ) has been installed in the beam line. In this paper principal of operation, instrumentation and programming of emittance meter are discussed. The emittance measurement has been carried out with the newly developed DEM at a beam energy of 3.2 MeV and a beam current of 10 mA. Typical rms emittance for x and y direction are measured to be 0.1303 and 0.1347 π mm mrad，which are well below the design standard of the RFQ.

	For the third-generation light sources, the vertical emit-tance of a few pico-meter-radians which can be achieved with good coupling correction close to 0.1%, will lead to very small beam size. Several microns vertical beam sizes measurement has presented challenges for diagnostic capability in this region. A few techniques have been developed to make a precise measurement, such as visible light interferometer, x-ray imaging using Fresnel zone plates, compound refractive lenses or pinhole camera. In this paper, an x-ray reflective optics method based on the Kirkpatrick'Baez mirrors will be emphasis on discussed. The K-B mirror system will be installed and tested in SSRF to obtain the vertical beam size close to 20 microns, which is expected to be used for several microns vertical beam size measurement in the future light source named HEPS (High Energy Photon Source) in China.

	The transverse emittance at C-ADS injector-I has been measured by the wire scanners at the Medium Energy Beam Transport-I (MEBT1). We have studied the effect of different fitting methods for obtaining the beam sizes on the emittance result, the result will be presented in this paper.
