    Abstract: A method for determining a property of earth formations surrounding a borehole, including the following steps: isolating a region of the borehole, and obtaining a sample of borehole fluid from the isolated region; and implementing measurements, dowhole, of the Raman scattering of electromagnetic energy directed at the fluid sample; the property of the earth formations being determinable from the measurements. In a disclosed embodiment, the steps of isolating a region of the borehole and obtaining a sample of borehole fluid from the isolated region include: providing a logging device in the borehole in sealing engagement with the isolated region, causing formation fluid from the isolated region to flow in a flow line of the logging device, and providing a measurement cell in the logging device which receives the sample of formation fluid via the flow line.

    Abstract: A radiation generator may include a generator housing, a target electrode carried by the generator housing, a charged particle source carried by the generator housing to direct charged particles at the target electrode based upon an accelerating potential, and a suppressor electrode carried by the generator housing having an opening therein to permit passage of charged particles to the target electrode. A target extender electrode may be between the suppressor electrode and the target electrode and have an opening therein to permit passage of charged particles to the target. At least one voltage source may be coupled to the target electrode, the suppressor electrode, and the target extender electrode to cause the target electrode to have a voltage greater than a voltage of the suppressor electrode and to cause the target extender electrode to have a voltage greater than the voltage of the suppressor electrode
