    Abstract: A system for measuring the direction of flight, velocity, charge, mass and chemical composition of micrometeoroids. The analyzer includes two spaced arrays of interconnected capacitors and an ion detector. Electrodes are fastened to the edge of each array. Micrometeoroids impinge on the arrays and generate signals at the electrodes. The magnitude of the signals is a function of the impact location. Ions accelerated from one array are focused on an ion detector to provide a time-of-flight mass spectrometer.

    Abstract: A detector for ionizing radiation of relatively low energy of the type in which a normally nonionized gas in a chamber connects two high-voltage electrodes and is ionized by radiation entering the chamber through a window in the chamber wall relatively permeable to the radiation, is provided with a window of fine wire gauze and continuously supplied with gas under a pressure sufficient to prevent entry of contaminants from the environment through the openings in the gauze. The screen window is more permeable to low-energy radiation than known windows.

    Abstract: the wavelength detector includes a diffusion element that diffuses the laser beam; a light collection optical system provided downstream from the diffusion element; a member, including an aperture, provided downstream from the light collection optical system; a discharge tube that is provided downstream from the member and that includes a cylindrical anode and a cylindrical cathode that each have a through-hole formed therein, and that is configured so that an electrical property between the anode and the cathode changes due to an opto-galvanic effect when a laser beam having a predetermined wavelength passes through the through-hole of the cathode in a state in which a DC voltage is applied to the anode; and a high-voltage DC power source. The discharge tube is disposed so that the laser beam that passes through the aperture passes through the through-hole of the cathode of the discharge tube without directly irradiating the cathode.
