“…In addition, several other conferences are devoted specifically to advances in this area. Finally, we note that the use of NTM within this field of research has seen a recent increase in interest due to the use of new chemical compositions in detectors (see, for example, Kodaira et al, 2009).…”

The aim of this paper is to provide an overview of the developments in nuclear track methodology as published in the proceedings of the last ten meetings of the International Conference on Nuclear Tracks in Solids (ICNTS) from the Marburg (Germany) conference in 1990 to the Bologna (Italy) conference of 2008. Nuclear Tracks Methodology (NTM)examines the effects of the interaction between charged particles and solid materials and presents several desirable characteristics: the detectors can easily be cut into a size appropriate for any application and can be used in locations for which other radiation detectors are not suitable; the etching and reading instrumentation is relatively simple; there is a quasiinsensibility to gamma radiation for reasonable dose exposures (typically < 1 kGy); after

“…An approach to raise the detection threshold of CR-39 is the use of a copolymer resin of CR-39 and diallyl phthalate (DAP) [47,48]. Although the CR-39-DAP detector is a candidate for the detection of heavy ions, charge resolution deteriorates due to the extremely rough surface conditions that result from chemical etching.…”

Due to the harsh radiation environment produced by strong laser plasma, most of the detectors based on semiconductors cannot perform well. So, it is important to develop new detecting techniques with higher detection thresholds and highly charged particle resolution for investigating nuclear fusion reactions in laser-plasma environments. The Columbia Resin No. 39 (CR-39) detector is mainly sensitive to ions and insensitive to the backgrounds, such as electrons and photons. The detector has been widely used to detect charged particles in laser-plasma environments. In this work, we used a potassium–ethanol–water (PEW) etching solution to reduce the proton sensitivity of CR-39, by raising the detection threshold for the research of laser-induced 11B(p, α)2α reaction. We calibrated the 3–5 MeV α particles in an etching condition of 60°C PEW-25 solution (17% KOH + 25%C2H5OH + 58%H2O) and compared them with the manufacturer’s recommended etching conditions of 6.25 N NaOH aqueous solution at 98°C in our laser-induced nuclear reaction experiment. The results indicate, with the PEW-25 solution, that CR-39 is more suitable to distinguish α tracks from the proton background in our experiment. We also present a method to estimate the minimum detection range of α energy on specific etching conditions in our experiment.

“…Nuclear fragmentation cross sections also give information about collision dynamics of high energy heavy nuclei like lead and uranium. Various techniques [3][4][5][6][7][8] have been employed for studies of nuclear fragmentation and other reactions, including solid state nuclear track detector (NTD) [9][10][11][12][13][14][15][16][17][18]. Here, we discuss experimental meth-ods and related problems for the measurement of fragmentation cross sections using NTDs.…”

The potential of the high resolution nuclear track detector (NTD) CR-39 is examined carefully for the measurement of relativistic nuclear projectile fragmentation cross sections and studies of related processes using the experience of many years of such measurements. The charge resolution and the charge resolving power of CR-39 detectors for the measurements of 158 A GeV 207 Pb projectiles and their fragments are presented. Exposures of target-detector stacks, the chemical etching procedure and the nuclear track measurements are described in detail discussing precautions and possible errors. The procedures discussed are also valid for other NTDs. A comparison with electronic active detectors is also made considering important detection and measurement aspects. An experimental design proposing the co-use of NTDs with in-use active detectors is described.
