The LRL Capture-Gamma Coincidence Spectrometer

Description: Abstract. A fast-slow coincidence scintillation spectrometer for gamma-gamma cascade measurements following thermal neutron absorption in nuclei is now in operation at the Livermore 1-megawatt pool-type reactor. Design features of the spectrometer and experimental techniques in its use are discussed with particular emphasis on the application of the recently introduced sum-coincidence method for analysis of capture-gamma double cascades. A new technique for the determination of added neutron bi… more

Magnetic Core Tests for Pulsed Operation at 30 Nanoseconds Pulse Width

Description: The magnetic properties of core materials ae investigated for a pulse width of 30 nanoseconds. Methods of testing which are necessitated by the sort pulse width are explained and the design of the pulser which is capable of 0.2 megawatt peak power is described. The data obtained if evaluated and presented for the various materials which were tested.

Observations on the Response of Two P-NJunction Diodes to Protons

Description: The response of a two silicon p-n junction diodes has been measured for protons up to 13.3 Mev. In one case the dependence of depletion layer thickness with bias voltage was found to be T or V(0.46). The observed resolution, made up of contributions from crystal noise, beam width, and scatterer thickness, was about 1% for 9-Mev protons.

Nine-Channel Polychromator For Observation Of Time-Dependent Spectral Line Profiles

Description: The instrument (polychromator) described observes time-dependent spectral-line profiles by simultaneous measurement at nine different wavelengths of light intensity as a function of time. A cylindrical lens magnifies the dispersion of a Jarrell-Ash Model S2000 Ebert Monochromator and forms an image on a light-pipe solder. Light pipes transfer light from various sections of the image--i.e., different wavelengths--to photomultiplier tubes, and the responses are displayed on oscilloscopes. The ins… more
