An 800 × 800 Texas Instruments virtual phase charge-coupled device (CCD) was used to obtain pinhole images and x-ray spectra of laser-produced, solid target plasmas. With the CCD used in the single-photon counting mode, the spectrum in the energy range 2-10 keV was obtained without a dispersive element. Typical spectra reveal two distinct temperatures: a "cold" component of approximately 200 eV and "hot" component of approximately 5 keV. Also, multiline spectra comprising characteristic line emission (K[sub α], K[sub β]) from a multilayer target bombarded by β rays were recorded using a three-phase CCD. The results demonstrate the potential of CCDs as imaging spectrometers with application in space, laboratory, and fusion plasma research.
