The iodine laser PALS operated at the fundamental 1ωo and third harmonic 3ωo frequencies (wavelengths 1315 nm and 438 nm, respectively) was used for the generation of plasmas of various Z-number targets. The investigation was performed at energies up to 800 J and 250 J for 1ωo and 3ωo, respectively, in the 400 ps pulses. In these conditions attention has been paid to the application of the solid state nuclear track detectors of the PM-355 type for measurements of parameters of ions emitted from the laser produced plasmas. Detector samples were masked with different Al-foil filters for making possible a rough estimation of ion energy. Track densities of the order of magnitude >107 tracks cm−2 were observed on the uncovered detectors and on detectors masked with 0.75 and 1.5 μm thick Al-foils. It confirms that Ag-, and Ta-ions of energy in the MeV range were emitted from the targets irradiated with the laser pulses. The ion streams were estimated on the basis of the track densities for different experimental conditions. The results were compared with those obtained with the use of ion collectors.

ヨウ素レーザーPALSは、基本周波数1ωoおよび第三高調波3ωo(それぞれ波長1315 nmおよび438 nm)で動作し、様々な原子番号のプラズマ生成に使用された。実験は、1ωoでは最大800 J、3ωoでは最大250 Jのエネルギーで、400 psパルスにおいて実施された。これらの条件下において、レーザー生成プラズマから放出されるイオンのパラメータ測定のためのPM-355型固体飛跡検出器の応用に注目が払われた。検出器試料は、イオンエネルギーの概算評価を可能にするため、異なる厚さのAlフィルターでマスクされた。フィルターなしの検出器、ならびに0.75 μmおよび1.5 μm厚のAlフィルターでマスクされた検出器上において、>10⁷ tracks cm⁻²のオーダーの飛跡密度が観測された。これは、レーザーパルス照射されたターゲットからMeV領域のエネルギーを持つAgイオンおよびTaイオンが放出されたことを確認するものである。イオン流は、異なる実験条件における飛跡密度に基づいて評価された。得られた結果は、イオンコレクターを用いて得られた結果と比較された。
