“…In this study, we have used a detector irradiated with particle to measure the VB [7]. Some initiatives have been undertaken in the last ten years to decrease etching time for speedier track development [9,10]. The objective of the research is to calculate registration characteristics such bulk etch rate VB, track etch rate VT, and etching ratio V. and etching characteristics such as the nuclear track detectors' diameter (d), number of tracks, and thickness of the removed layer (h), which are etched with a NaOH solution such as the nuclear track detectors' diameter (d), number of tracks, and thickness of the removed layer (h), which are etched with a NaOH solution…”

In this work, we use three different etching techniques—water bath, microwaves, and hotplate stirrer devices—in an effort to confirm the optimal etching time and conditions for tracks in the CR-39 solid-state nuclear track detector following irradiation to an alpha particle source (241Am). The research shows that the water bath’s maximum track density is 57596 tracks/cm2, appearing at 90 and 150 minutes. On the other hand, the hotplate stirrer’s maximum track density is 28050 tracks/cm2, appearing at 90 and 150 minutes. The microwave is the best etching method since it generated the tracks (65076 tracks/cm2) in a relatively short amount of time (10 min). The computation of the etching parameters, which are the bulk etch rates (VB), track etch rate (VT) and track etch ratio (V), was investigate in the etching properties. The time for the appearance of all traces of the microwave device is at a time of 10 minutes, followed by a hotplate stirrer at a time of 90 minutes, then a water bath at a time of 120 minutes.

“…There are several devices used for etching SSNTDs: water bath, microwave and ultrasound, and all of them provide heat to the etchant solution in addition to specific waves in microwaves and ultrasound devices which is used to speed up the etching process. The etching time is reduced and the track edges are found to be smooth and well defined [2].…”

In this research we try to investigate the optimum etching time for the tracks originate in (CR-39) solid state nuclear track detector after irradiated with alpha source (241 Am) using three different etching techniques: the traditional method (water bath), microwaves and ultrasound devices. The track etching parameters: bulk etch rate (VB), track etch rate (VT), track etch rate ratio evaluates (V), critical angle (θC), and etching efficiency (η) were calculated in this research. It's seen that the optimum etching time was ranging with (60-150 min), (20-30 min) and (60-120 min) when etching with water bath, microwave and ultrasound respectively. Also we observed that the critical angle was (24.29) when etching CR-39 detector with microwave. This value is lower than the critical angles values for the detector etched with water bath or ultrasound; thus it can be the optimum magnitude because its decrease leads to increasing the number of the tracks appeared in the detector and the etching efficiency.

“…There are new approaches to deal with extremely dense overlapping tracks [29,30]. Recent developments of rapid etching techniques [31,32] can be adopted to reduce the etching time significantly. Effectiveness of these etching methods is discussed in section 8.…”

Solid polymeric track detectors (SPTDs), due to their insensitivity to low LET radiations and integrating nature of signal registration, are found to be effective and convenient for neutron measurements, particularly in pulsed and mixed radiation fields such as in particle accelerator environments. This paper in addition to reviewing some of the existing methods of neutron spectrometry and dosimetry, explores new approaches on the use of SPTDs for neutron measurements, elaborates on the extended energy response and rapid etching techniques of SPTDs along with some new results. Microwave induced chemical etching (MICE) technique, recently introduced for rapid and efficient processing of track detectors is discussed in the paper.Contents of Paper
