Switching Vacuum Arc in a Pulsed Transverse Magnetic Field
An experimental analysis of the vacuum arc behavior in a pulsed transverse magnetic field with amplitudes up to 120 mT and frequency of 900 Hz is presented in the paper. The arc was produced between Cu contacts during the switchingoff operation of the current half-wave of amplitude 500 A and frequency of 30 Hz, so that the circuit parameters had rather moderate values which are easy to obtain i...
متن کاملa generalization of strong causality
در این رساله t_n - علیت قوی تعریف می شود. این رده ها در جدول علیت فضا- زمان بین علیت پایدار و علیت قوی قرار دارند. یک قضیه برای رده بندی آنها ثابت می شود و t_n- علیت قوی با رده های علی کارتر مقایسه می شود. همچنین ثابت می شود که علیت فشرده پایدار از t_n - علیت قوی نتیجه می شود. بعلاوه به بررسی رابطه نظریه دامنه ها با نسبیت عام می پردازیم و ثابت می کنیم که نوع خاصی از فضا- زمان های علی پایدار, ب...
Magnetic properties of nanoclusters formed by implantation of Fe into Ge using a metal-vapor vacuum arc ion source
The magnetic properties of Fe ions implanted into a germanium crystal by metal-vapor vacuum arc ion source were investigated using a Quantum Design SQUID magnetometer. The presence of Fe nanoclusters in Ge was verified by magnetization measurements. A Langevin fit was used to obtain the size distribution of the clusters. The results demonstrated that the clusters are magnetic. The magnetic beha...
متن کاملA Novel Method for High Current Vacuum Arc Interruption Using Externally Applied Ultra High Axial Pulsed Magnetic Field
Axial Magnetic Field (AMF) is widely used in vacuum interrupters to keep the arc in the diffused mode. With increasing axial magnetic field, the multiple arc mode extends to higher arc currents. In this mode of arc, the fault current can be easily interrupted due to fast recovery of the diffused vacuum arc. The magnetic field amplitudes considered in the preceding studies are all less than hund...
متن کاملProduction of large metallocarbohedrene clusters using a pulsed arc cluster ion source
The hypothesis of the existence of multi-cage structures of metallocarbohedrene clusters (“metcars”) bases on the observation of certain magic numbers in the mass spectra corresponding to an excess of carbon atoms with respect to the bulk stochiometry (1:1 for TiC). E.g., the appearance of the magic number cluster Ti13C22 has been explained by assuming a double-cage structure. However, the same...
