Abstract.A fast-decay and low-afterglow liquid scintillator was developed for the fast ignition experiment at the Institute of Laser Engineering (ILE). The liquid scintillator was coupled to a gated photomultiplier (PMT), and the gating performance under high-intensity -rays was experimentally checked. In 2010, a detector with a high detection efficiency of 10 −4 was developed and installed in this experiment. The neutron yield in the fast heating experiment was successfully measured using this detector.

“…Therefore, it is necessary to develop a fast-response and low-afterglow scintillator. R. Lauck et al and C. Stoeckl et al have already reported very low afterglow liquid scintillators [1,2]. This scintillator consisted of a xylene solution with a fluorescent dye quenched by oxygen gas.…”

“…Figure 2 shows the comparison of the scintillation afterglow and the fast decay component of the BBQ scintillator and BC-422Q. Scintillation afterglow was measured by Time-Correlated Single Photon Counting method [4]. In order to measure the fast decay profile of these scintillators, a silica glass cell was filled with the mixture and then irradiated by 150-fs, frequencytripled (290 nm) Ti: sapphire laser pulses, having 20 µJ pulse energy and operating at 1-kHz repetition rate [7].…”

The progress on the neutron time of flight (nTOF) detection system for Fast Ignition (FI) related experiment was presented. The novel nTOF detector consists with custom-developed liquid scintillator and gated PMT was implemented. The origin of the harsh backgrounds which had been observed in previous experiment was identified by Monte Carlo simulation. The neutron yield around 10 6 in the 1 kJ-heating experiment which is 10 times lower than previous lower limit was clearly diagnosed.

Organic single crystals (OSCs) have ideal qualities (well defi ned structure and\ud morphology, lack of grain boundaries, high purity, 3D long range order, good\ud electronic transport properties) for several technological applications, in particular\ud as key components for electronic devices. It is only recently that OSCs\ud have been considered as ionizing radiation detectors, and the latest developments\ud in this fi eld are here reported. In the fi rst section, various methods for\ud OSC growth are described, with emphasis on cost-effective, solution-based\ud approaches capable of delivering large volume, well performing crystals. The\ud second section is focused on the use of solution-grown OSCs as scintillators\ud (i.e., as high energy photon to UV–vis photon conversion), highlighting\ud the ability of cm-scale OSCs to effectively detect neutrons and to carry out\ud neutrons-gamma pulse-shape discrimination tasks. Finally, the third section\ud describes the use of semiconducting, solution-grown OSCs as effective\ud solid state direct detectors (i.e., directly converting high energy photons into\ud charge carriers), evidencing extremely promising performances in terms of\ud operability in environmental conditions (i.e., no need for encapsulation),\ud radiation hardness, linear response and low operating voltage
