Small Nanosecond-Discharge Capacitors Low-energy ultrafast capacitors are often used for producing nanosecond light ñashes. The spark gap is incorporated in the capacitor itself. The candlepower (CP) peak light is approximately proportional to the peak of current voltage . ) 8. MEASUREMENTS OF U L T R A L O W I N D U C T A N C E ( N H ) CAPACITORS 41 H. 2 kV; duration 25 nsec(l/2 light). 5kV; duration 7 nsec (1/2 light). A paper by Yguerabide discusses the generation and detection of subnanosecond light pulses which are used to study the luminescence of different materials.
Since the micas are usually encased in resin, they have superb environmental properties and operate at over 200 C. a. Off-the-shelf Cases Cost Less Any capacitance value can usually be made tofitany case, but the capacitor may have a lifetime of only one pulse. For best reliability, allow the largest size possible and demand to know the expected lifetime of the model under the specified conditions. Choosing the case tofitthe available space is an expensive approach. A great variety of off-the-shelf cases are available, all much less expensive than a custom container.
7 μsec. 1 kV/cm. A fourth capacitor bank was being added to the Scylla IV system to extend the magnetic compression field of the primary bank both in magnitude and time. This ''power crowbar" bank had 3 Μ J of energy storage at 20 kV. This bank was expected to increase the magnetic field in the 1-m coil to more than 200 kG with a half-period of ^ 50 ^sec. Today batteries with more than 2 Μ J are being used for plasma experiments. e.
