Design of a pulsed X-ray system for fluorescent lifetime measurements with a timing accuracy of 109 ps

Femtosecond laser-driven x-ray tube

“…Our work extends the results of Anderson et al, 13,14 Tomov et al, 15,16 Derenzo et al, 17 and, more recently, of Girardeau-Montaut et al 18 who have demonstrated x-ray tubes driven with nano-and picosecond laser pulses.

Ultrafast X-ray Absorption Spectroscopy

“…These are then accelerated to several tens of kiloelectronvolts and generate characteristic line emissions and continuous bremsstrahl- ung at the target anode. With 100 fs optical pulses an X-ray pulse width around 1-2 ps was already demonstrated, 112 thus extending the efforts with nanosecond and picosecond lasers by Rentzepis et al, 43,[113][114][115][116][117][118] Derenzo et al, 119 and Girardeau-Montaut et al 120 This technique delivers continuum spectra, but it is not very widespread due to its low efficiency. So far only one group has recorded an X-ray absorption spectrum ∼10 ns after the pump pulse with such a source.…”

Growth by Bridgman method and luminescence properties of Na:PbFCl crystal

“…The decay time was measured with the pulsed X-ray facility described in detail by Derenzo [14]. Light from a pulsed laser diode incident on a photo-cathode generates a pulse of electrons that are accelerated and bombards on a tungsten anode, producing a 30 KeV X-ray pulse.…”
