摘要： A cryogenic apparatus for microscopy of physical properties of an object including a thin, stiff, transparent substrate or window (28) within the outer wall of the vacuum space (18) of a dewar and a cryogenic sensor (72) within the vacuum space and spaced very close distances to the window (28). This construction allows for positioning a sample for measurement outside of the vacuum space, at room temperature or higher and for microscopy of physical properties of the sample (91) by monitoring the output from the cryogenic sensor as it is scanned along the surface of the sample (91).

摘要： Bei einem Verfahren zur Aufnahme von lonen-Zyklotron-Resonanz-Spektren bzw. einer Vorrichtung zur Durchführung des Verfahrens werden gasförmige lonen einer Probensubstanz in einem Ultrahochvakuum gleichzeitig einem Konstantmagnetfeld B. und einem dazu senkrecht gerichteten Hochfrequenzfeld ausgesetzt, wobei Resonanzen dann angeregt werden, wenn die Frequenz des Wechselfeldes der Umlauffrequenz der sich im Konstantmagnetfeld auf kreisförmigen Bahnen bewegenden lonen entspricht. Zur Erzeugung der gasförmigen lonen der Probensubstanz wird diese mit weiteren gasförmigen, energiereichen lonen einer Primärsubstanz beschossen. Die Primärionen werden in der Meßzelle durch einen Elektronenstrahl erzeugt und durch Ionen-Zyklotron-Resonanz auf ein hohes Energieniveau angeregt (Figur 2).

摘要： The invention relates to a novel apparatus for detecting as well as quantifying superconductivity characterized by a rigid-stemmed pendulum used to support the superconductive sample for free-swinging movement about a low-friction fulcrum in a magnetic field effective to swing the pendulum to one side, connecting both a first mechanism to the pendulum operative to sense the movement of the pendulum and generate a signal proportional thereto along with a second mechanism effective to receive such a signal from the first mechanism and react thereto in a manner to null the movement of the pendulum along with the sample suspended therefrom, and, finally, connecting a signal processing mechanism into the system whereby the signal generated by the first mechanism is quantified as a measure of the superconductive properties of the sample. The invention also encompasses the method for detecting and quantifying the superconductive properties of a purportedly superconductive sample which includes suspending the sample from a rigid-stemmed pendulum within a magnetic field effective to repel same when exhibiting the Meissner Effect, detecting the repelling force tending to swing the pendulum and measuring it as a quantification of the Meissner Effect force present in the superconductive sample, and nulling the swing of the pendulum by applying an oppositely-acting force thereto equal to the repelling force.

摘要： A level gauge for liquid helium comprising a sensing element in the form of a ribbon wire made of superconductive alloys and a tube supporting the sensing element, which tube is inserted into liquid helium upon measurement. The superconductive alloys are represented by a formula Zr.sub.100-x.(Ru.sub.y.Rh.sub.1-y).sub.x in which x represents contents of Ru and/or Rh in atomic % and in a numerical value of 22.5.ltoreq.x.ltoreq.27.5 and y represents a numerical value of 0.ltoreq.y.ltoreq.1. The alloys are made of an amorphous phase obtained by rapid quenching a molten alloy material and have a superconducting transition temperature, Tc, of 4.2.degree. to 4.5.degree. K. When the level gauge is immersed in liquid helium, a portion of the sensing element below the level of the liquid helium has a zero electric resistance because of the superconductivity of the alloy, so that the level of the liquid helium can be detected by a variation in resistance of the sensing element.

摘要： A method and apparatus for imaging objects utilizing acoustic waves at frequencies above 4.2 Ghz and up to 8 Ghz wherein the transducer and the object imaged by waves or beams from the transducer are both at a temperature no greater 0.2.degree. K. The transducer is driven by pulses generated by a short pulse generator which are stretched and coded by a dispersive filter and inductively coupled to a low temperature coupler to be use to drive the transducer. The frequency returns are carried by the same bidirectional coupler to a low noise amplifier. Both the low noise amplifier and bidirectional coupler are maintained at a temperature of less than 4.2.degree. K. The output of the amplifier is then coupled to a dispersive filter which responds the coding in the first dispersive filter to decode the information and reconstruct the signal. Subsurface defects are detected by heating the object while it is inspected by the acoustic transducer.

摘要： An improved apparatus and method for analyzing the chemical and structural composition of a specimen including whole-body specimens which may include, for example, living mammals, utilizing nuclear magnetic resonance (NMR) techniques. A magnetic field space necessary to obtain an NMR signal characteristic of the chemical structure of the specimen is focused to provide a resonance domain of selectable size, which may then be moved in a pattern with respect to the specimen to scan the specimen.
