Different shapes of tracks in phlogopite, biotite and soda lime glass

Abstract

Etched track opening geometries in Biotite, Phlogopite and soda-lime glass irradiated with swift heavy ions [ 197 Au(11.64 MeV/n), 136 Xe(11.56 MeV/n), 58 Ni(11.56 MeV/n)] at different angle of incidence have been studied using appropriate chemical etching technique. Different geometries (Hexagonal, irregular polygon, triangular in case of Biotite and Phlogopite, and circular & elliptical in case of soda lime glass detector) of heavy ion tracks are reported in the present investigations using optical microscope. The different shapes of these heavy ions track geometries are found to be related with various target-projectile parameters (viz : type of projectiles, energy, stopping power, angle of incidence of the projectile, density of defects and its reactivity with etchant, etching conditions and chemical structure of the detectors). The dependence of different shapes of heavy ion tracks in isotropic and anisotropic medium on the variation of radiation damage densities along the ion trajectories have also been discussed in the present paper.

An exploration of lattice transformation mechanism of muscovite single crystal under EB irradiation at 0–1000 kGy

“…If mater is rigid as a perfect crystal, all atoms are linked together with compact stacking with no vacancy, any atom slide might deteriorate stacking regularity, inducing lattice disorderliness. This situation is common especially to compactly stacked mater under ion irradiation 19–21 . If mater is stacked loosely with vacancy or hydrogen/ionic bond existence, adjacent layers might readily slide.…”

“…This sit-uation is common especially to compactly stacked mater under ion irradiation. [19][20][21] If mater is stacked loosely with vacancy or hydrogen/ionic bond existence, adjacent layers might readily slide. Even a feeble fluctuation within ionic/hydrogen bond could alter lattice size.…”

Heavy ion range anisotropy in muscovite mica

“…Since the ionic bonding between the K + layers and the trilayer aluminosilicate sheet is weak, mica cleaves rather easily at the positions of the K + layers. The most stable surface [0 0 1] was used for heavy ion irradiation after cleaving the muscovite crystal [7,24].…”

“…Among various radiation detecting materials, the minerals (e.g., Mica) provide unique opportunity to measure the radiation effects and defects because of the better measurement of damage [7,[22][23][24][25][26]. The irradiated mica can provide enormous important applications in science and technology.…”

Intensive study on structure transformation of muscovite single crystal under high-doseγ-ray irradiation and mechanism speculation

“…In this case, designing new material or evaluating the existing material to ensure whether it is suitable for detecting high-dose irradiation or not is useful. Nowadays, numerous materials have been evaluated such as polymers, semiconductors (silicon), glass and calcium fluoride (CaF 2 ) [11]. However, they are probably not useful because of certain disadvantages.…”
