The Cerenkov background is supprcssed by adding a coincident gate.

Using coincidence method, transit time spread (TTS) is measured with Cherenkov light produced by cascade γ radioactive source, 60Co on photocathode window of photomultiplier tube (PMT).

A method for measuring TTS of photomultiplier with Cherenkov lightproduced by direct gamma ray illumination on glass windowis presented and theexperi mental result for fine-mesh R5924 is given.

An online beam spot diagnostic system for high current,short pulse electron beam based on Cerenkov radiation is introduced.

A new way in electron beam emittance measurement with Cerenkov radiation "double imaging" method is proposed in this paper.

Cherenkov radiation in a plasma-filled, dielectric coaxial waveguide;

Using the proton exchanged MgO∶LiNbO 3 planar optical waveguides,the characters of Cerenkov second harmonic generation of infrared laser diodes were studied,the direct frequency doubling of 956nm and 804nm laser diodes were realized and 478nm blue and 402nm violet light are generated.

After interaction nuclides was removed using TRPO solvent extraction, Determination of radioactivity of 90Sr or 90 Y in waste water using Cerenkov counting method is studied.

Cerenkov counting method is studied for determination of "K in geawater and plants.
