A new high photon energy (hν > 15 keV) time-integrated pinhole camera (TIPC) has been developed as a diagnostic instrument at the Z facility. This camera employs five pinholes in a linear array for recording five images at once onto an image plate d

A new x-ray beam chopper has been designed and tested at the Advanced Photon Source. This beam chopper uses the diffractive properties of a rotating crystal to produce transmission window times as short as about 10 ns from a single diffracting face f

An explanation is presented for the recently reported striking differences in the kilovolt Xe L-shell x-ray emission from Xe cluster targets excited by comparable terawatt ultraviolet (248 nm) and infrared (800 nm) femtosecond laser pulses under near

A direct comparative measurement of the dependence on the wavelength of irradiation of the kilovolt x-ray yields ( and ) multiphoton-induced from Xe clusters by excitation with intense femtosecond pulses at 248 and 800 nm has been made. The spectrosc

The role of Raman heating of plasma electrons and the subsequent thermal generation of Xe(M) emission from Xe cluster targets has been examined through studies of the spatial and spectral properties of the observed x-rays. Several experiments conduct

Examination of the intensity dependence in the range of the multiphoton-induced Xe(L) spectrum from Xe clusters has demonstrated (i) a very high sensitivity for the production of ions having multiple vacancies and and (ii) a reduction of the average

The analysis of X-ray emission from channeled propagation occurring in gas-phase Xe cluster targets provides evidence that multiphoton coupling can produce an atom-specific power exceeding 1 W/atom. This exceptionally high rate is found to be consist
