In this work, the anode-cathode distance in a direct current glow discharge is reduced manually to values smaller than the Child-Langmuir extent, while the discharge current, the discharge voltage and the Langmuir probe current are monitored continuously. The discharge current is observed to develop a large peak as soon as the sheath edge contacts with the anode, then decays to negligible values for a certain time interval, after which, this cycle starts repeating itself periodically. A model is described to interpret the behavior of all three quantities self-consistently. The experiment is performed with different anode-cathode distances and the implications of the observations regarding ion implantation processes are discussed. (C) 2002 American Institute of Physics.

Applications of ions produced by low intensity repetitive laser pulses for implantation into semiconductor materials
Wolowski, J.; Badziak, J.; Czarnecka, A.; Parys, P.; Pisarek, M.; Rosinski, M.; Turan, Raşit; Yerci, Selçuk (2008-01-01)
This work reports experiment concerning specific applications of implantation of laser-produced ions for production of semiconductor nanocrystals. The investigation was carried out in the IPPLM within the EC STREP 'SEMINANO' project. A repetitive pulse laser system of parameters: energy up to 0.8 J in a 3.5 ns-pulse, wavelength of 1.06 mu m, repetition rate of up to 10 Hz, has been employed in these investigations. The characterisation of laser-produced ions was performed with the use of 'time-of-flight' io...
Micro processing by intense fast electron beam
Goktas, H; Kirkici, H; Oke, G; Udrea, M (2001-06-22)
Generation of intense electron beams by superposing two discharges, namely a low pressure do glow discharge and a high current pulsed discharge at pressures and voltages very similar to that of the pseudo-spark gap devices, has been reported previously [1, 2]. The small diameter, high peak current and short pulse length are the characteristics of the electron beam generated using this technique. In this technique, no high vacuum facilities are necessary, and many applications such as micro processing, X-ray...
Spatial variations of non-uniform argon glow discharge
Akbar, D.; Bilikmen, S.; Akbar, H. (Springer Science and Business Media LLC, 2006-01-01)
The spatial variation of a non-uniform glow discharge due to the different diameters of the same discharge tube on the plasma parameters is attracting a considerable attention. For this reason the fundamental spatial plasma parameters of an argon. glow discharge have been measured by using fast three couple of Langmuir double probe (TCDP) technique. The orbital motion limited (OML) theory has been used, since the probe radius is smaller than Debye length xi < 1. The axial and radial variation of the electro...
Charging and discharging li-on battery by using two-quadrant chopper circuit topolojies in space applications
Akin, Metin (2007-06-16)
From the first time of mini-satellite to this time, Ni-Cd batteries has generally been used for power system of satellite because of its smooth discharge characteristics. It is now, in contrast to this, it has low energy density when compared with some other batteries. So, li-ion battery can be alternative to it in space applications. To achieve this goal, a circuit was designed to charge/discharge li-on battery, payload of our satellite (RASAT) which will be launched two years later, will be used as main e...
Spatial stabilization of Townsend and glow discharges with a semiconducting cathode
Salamov, BG; Ellialtioglu, S; Akınoğlu, Bülent Gültekin; Lebedeva, NN; Patriskii, LG (IOP Publishing, 1996-03-14)
The physical processes determining the functions of an ionization system and especially the discharge stabilization by the distributed resistance of a semiconducting cathode in such a system are studied. The current-voltage (I-U) characteristics of the system with a semiconducting GaAs cathode are obtained experimentally as functions of the gap pressure P (16-760 Torr) and inter-electrode distance d (10 mu m to 5 mm), which are varied for the first time over very wide ranges. The experiments showed that the...
