“…When 30 µm is removed, this density will be reduced to only 15 tracks.cm -2 which is about 9 times smaller thus reducing the MDL of the PCTD significantly for low-dose low-fluence charged particle applications. It seems the observed effects of the frequency on the BGT characteristics can be related to some phenomena as discussed above (Tommasino and Armellini, 1973, Sohrabi, 1975, 1980, 1985, 1986, Wong and Tommasino, 1982, Hassib and Piesch, 1978, Sohrabi et al 2012, Olszewski et al, 1982, Boyang, 1984, Singh and Virk, 1987. As shown in Figure 3, by increasing the frequency for each thickness removed, the BGT density and diameter increase especially when no layer removal has been performed.…”

“…The electrochemical etching (ECE) of charged particle tracks in polymer track detectors has been the subject of research and development as well as applications for over 4 decades (Tommasino and Armellini, 1973, Sohrabi, 1974, 1975. The ECE method is governed by a large number of chemical and physical parameters in particular the applied electric field strength and frequencywhich have been under some theoretical and experimental studies (Tommasino and Armellini, 1973, Sohrabi, 1974, 1975, 1980, 1985, 1986, Wong and Tommasino, 1982, Hassib and Piesch, 1978, Olszewski et al, 1982, Boyang, 1984, Singh and Virk, 1987, Sohrabi et al 2012. Some frequency studies have been focused on polycarbonate track detectors (PCTD) (Sohrabi, 1975, 1980, Wong and Tommasino, 1987, Singh and Virk, 1987, Hussain and Khan, 1988.…”

“…Wong and Tommasino (1982) concluded that the power dissipation is an important factor on the alpha-exposed PCTDs up to 1 MHz using Maxwell-Wagner interfacial polarization theory. Olszewski et al (1982) studied the vibration of LR-115 under a forced harmonic oscillation to justify a "resonance-type effect" in frequency responses. Boyang (1984) reported the electrostriction in ECE and measured the vibration of CR-39 foils by the Michelson interference (He-Ne laser).…”

Polycarbonate track detectors (PCTD) when electrochemically etched (ECE) provide excellent characteristics for registering relatively lower-LET charged particles (e.g. alphas, fast-neutroninduced recoils) for many health physics and ion detection applications.The layer removal method of PCTDs by ethylenediamine (EDA) developed in our laboratory reduces the background track (BGT) density significantly. The frequency of the applied electric field strongly affects the BGTdensity and diameter and thus affects the minimum detection limit (MDL). In order to study the combined effects of the frequency and layer removal on the BGT density and thus on the MDL, this research was conducted. The BGT density versus the layer thickness removed at frequencies up to 12 kHz decrease rapidly to about 10-20 µm above which they reach aminimum constantlevel, while the mean BGT diameter verses layer removed at all frequencies are constant with flat responses. On the other hand the BGT density and diameter versus frequency at different layers removed up to ~50 µm increase till 4 kHz above which they reach plateaus. The PCTDs with ~20 µm layer removal at frequencies up 1 to 2 kHz showed the lowest MDL. The results are presented and discussed.
