Experimental diagnoses of plasma electron density by interferometry using an x-ray laser as probe
利用x射线激光干涉诊断等离子体电子密度

The interferometry with an x-ray laser as probe is an important tool of diagnosing the electron density of a high temperature and dense plasma. A successful experiment of diagnosing the density of a CH plasma was demonstrated by using a Ni-like Ag x-ray laser as a probe and a Mach-Zehnder interferometer as instrument under the ShenguangII laser facility. The legible interferogram indicating the information of electron density was obtained.
