New design techniques facilitate a high reliability 1T1C 8Mb ferroelectric random access memory with 0.71u<sup>2</sup> cell operating at 1.5V on a 130nm 5LM Cu process. Zero cancellation increases the cell interrogation voltage by using a nonswitching ferroelectric capacitor to remove charge from the bit line that compensates the linear charge from the cell(More)
High-frequency (5 to 40 millihertz) induced lunar magnetic fields, observed at the Apollo 15 site near the southeastern boundary of Mare Imbrium and the southwestern boundary of Mare Serenitatis, show a strong tendency toward linear polarization in a direction radial to the Imbrium basin and circumferential to the Serenitatis basin, a property that could be(More)
The quantum mechanical description of atomic spectra was the beginning of a new era of quantum physics which today is the theoretical basis of nuclear and solid state physics, chemistry, and biochemistry [1,2]. Quantum mechanics opened also a new look to solid state physics which will be illustrated by the development of the conception of excitons [3]. One(More)
Cats were tested for their ability to follow a dot target which periodically jumps horizontally from side to side. They can learn to perform saccadic tracking of various stimulus frequencies, and often they produce saccades predicting the target displacements. The preferred stimulus frequency for response to synchronize was in the 0.5-Hz range. Cats tend to(More)
LiF crystals exposed to swift heavy ions exhibit unexpected coloration phenomena at a depth up to 3 mm beyond the ion range. The induced color centers were investigated by thermo-stimulated luminescence, optical absorption, and nuclear magnetic resonance (NMR) spectroscopy. The crystals were irradiated with various ions from C to U at the UNILAC accelerator(More)
Fine-grained isotropic graphite R6650 (SGL Carbon) has been selected for manufacturing the production target and the beam catchers at the planned Super-FRS fragment separator [1] at FAIR. Failure criteria due to irreversible ion-beam induced damage of these components are related to dimensional changes, degradation of the mechanical strength due to defect(More)
Spatially resolved (19)F and (7)Li nuclear magnetic resonance (NMR) spin-lattice relaxation rates have been measured in LiF crystals irradiated with 1.44 GeV Xe ions at fluences from 10(10) to 10(12) ions cm(-2). In addition, the F-centre concentration has been measured by optical absorption spectroscopy and the concentration of paramagnetic centres by(More)
Single crystals of LiF were irradiated with 5-MeV Au ions at the Porto Alegre 3 MV Tandetron implanter applying fluences Φ between 10 and 10 ions/cm. The beam current (i) was varied from 1 to 200 (± 0.1) nA equivalent to ion flux φ [ions/cms] = 3.1×10·i [nA]. The range R of the ions is ~1 μm, which is much smaller than the thickness of the crystals. The(More)
We have studied the colour centre production in yttria-stabilized zirconia (ZrO(2):Y(3 +)) by heavy ion irradiation in the GeV range using on-line UV-visible optical absorption spectroscopy. Experiments were performed with 11.4 MeV amu(-1) (127)Xe, (197)Au, (208)Pb and (238)U ion irradiations at 8 K or room temperature (RT). A broad and asymmetrical(More)
