	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.

	Position monitoring, tune calculation and subsequent optimization of hadron circular accelerators requires specific instrumentation. Libera Hadron is the newly developed instrument intended for data acquisition and post processing of signals from shoe-box or capacitive type pickups. Development, initial measurements and verification of the instrument performance were conducted in the Instrumentation Technologies' laboratories, followed by the characterization measurements of the unit carried out at Facility for Anti-proton and Ion Research (FAIR) facility. This article discusses the new BPM electronics concept, the tests performed and the performance obtained.

	The HRMT27-Rodtarg- experiment used the HiRadMat facility at CERN to impact intense 440 GeV proton beams onto thin rods -8 mm diameter, 140 length- made of high-density materials such as Ir, W, Ta, Mo among others.

The experiment was designed to recreate the extreme conditions reached in the named target, estimated on an increase of temperature above 2000 °C in less than 0.5 μs and a subsequent compressive-to-tensile pressure wave of several GPa. The goals of the experiment were to validate the hydrocode calculations used for the prediction of the antiproton target response and to identify limits and failure mechanisms of the materials of interest. In order to accomplishing these objectives, the experiment counted on extensive online optical instrumentation pointing at the rod surfaces. Online results suggest that most of the targets suffer important internal damage even from conditions seven times lower than the reached in the AD-target. Tantalum targets clearly showed the best dynamic response.
