Date Oct. 24, 1996Streak camera whereof the pulse converter for converting a photon pulse for detecting into an electron stream comprises a gaseous medium. A streak camera for a photon pulse in the far-infrared region is provided with a laser source to bring particles in the medium into a Rydberg state, in a streak camera for an X-ray pulse the medium contains particles for bringing into an Auger state, and additional deflection plates are provided for separating a primary electron stream from a secondary electron stream.

    Abstract: Semiconductor device with two photodiodes, each having maximum spectral sensitivity at a different wavelength, comprises a n (or p)-type substrate, a p (or n)-type dish-shaped zone (A) adjacent to the surface of the substrate, and a n (or p)-type zone (B) entirely surrounded by zone A and the surface. The improvement is that zone B has a much lower dopant concn. than zone A. The device may be used as a dual-spectrum photodiode or phototransistor, e.g. in photocopiers, spectrophotometers, alpha-particle detectors, etc. The improvement increases the blue sensitivity of the devices (cf. US4011016).

    Abstract: This spark gap is used to discharge a capacitor through a gas laser circuit to produce very short pulses of ultra violet light. The problem with conventional spark gaps used to supply pulses of a few nano-seconds is that the self-inductance of the gap extends the pulse rise-time, thus reducing the power of the pulse. The usual rate of rise of 10 to 40 kV/nano-second can be increased to greater than 60 kV/nano-second by adding a third electrode (4) separated from the two spark gap electrodes (2,3) by an insulated substrate (1). The third electrode is connected to one of the other two. The self-inductance is then reduced from a value proportional to the width of the gap to a value proportional to the thickness of the insulated substrate.

    Abstract: 1,166,755. Thermonuclear apparatus. STICHTING VOOR FUNDAMENTEEL ONDERZOEK DER MATERIE. 4 July, 1967 [7 July, 1966], No. 30749/67. Heading G6P. In a thermonuclear fusion device, a toroidal plasma is enclosed within a cold gas blanket inside a containment vessel. The gas is injected through pipes tangential to the containment vessel so as to cause the gas to rotate about the toroidal axis. By centrifugal action the gas assumes a position surrounding the plasma. External coils produce the internal toroidal magnetic field. A current is induced in the plasma by further external coils to effect plasma heating.
