Experimental results are presented obtained with a cryogenically cooled high-resolution X-ray spectrometer based on a 141 × 141 µm Nb-Al-Al2O3-Al-Nb superconducting tunnel junction (STJ) detector in an SR-XRF demonstration experiment. STJ detectors can operate at count rates approaching those of semiconductor detectors while still providing a significantly better energy resolution for soft X-rays. By measuring fluorescence X-rays from samples containing transition metals and low-Z elements, an FWHM energy resolution of 6–15 eV for X-rays in the energy range 180–1100 eV has been obtained. The results show that, in the near future, STJ detectors may prove very useful in XRF and microanalysis applications.

This paper offers a close reading of the contemporary Russian writer Vladimir Sorokin’s Ice trilogy and explores its deep roots in early gnostic spiritual movements of late antiquity, Russian esoteric philosophy and literature, and Western popular culture. Reflecting sources as varied as the Apocryphon of John, the Disney movie Escape to Witch Mountain, Russian New Age paganism, and esoteric Soviet science, these three interconnected novellas are based on the real-life “Tunguska event,” the great fireball that appeared over the Tunguska region of Siberia in 1908, flattening more than 800 square miles of forest. Famous in ufo circles as the “Russian Roswell” and long a magnet for esoteric speculation, in Sorokin’s hands this probable meteor strike becomes the springboard for a contemporary gnostic fantasy in which a giant chunk of ice carries the spirits of 23,000 gnostic demiurges to earth, where they inhabit human bodies that they despise and seek only to reunite and return to their source. More than a simple postmodern parable of the seventy-year Soviet regime and post-Soviet societal excesses, Sorokin’s damning portrait of his “children of the Light” illuminates the deeper and darker currents of human nature, ethics, and spirituality.
