equipment

Nanosecond pulse generation and recording system for conductivity investigations of thin films
Nanosecond pulse generation and recording systemconsists of ns pulse generator (pulse length 5-900 ns, rise time 0.5 ns, max. Amplitude 2 kV), closed cycle helium gas cryocooler which ensures measurements in the temperature range (4.2-320)±0.01 K, 50 W impedance 10 GHz bandwidth transmission line, 30 ps pulse duration laser and 6 GHz Tektronix or 16 GHz Tektronix  real-time oscilloscopes.

 

 

Setup for measurements of conductivity in permanent magnetic field in wide temperature range
Setup for measurements of conductivity of films in permanent magnetic field up to 0.9 T in the temperature range 4.2-320 K. It consists of closed cycle helium gas cryocooler and electromagnet with programmable power supply (Agilent Technologies N5769A). The measurements are automated by using „LabView“ software. There are two programmes: one for automated measurement of conductivity dependence on temperature; the other one for measurement of conductivity dependence on magnetic field.

 

Setup for measurements of conductivity in permanent magnetic field
Setup for investigations of electrical conductivity up to magnetic field B = 2.4 T in the temperature range 270-350 K. It consists of two parts. Temperature stabilization is made by using Peltier element.  Electromagnet with programmable power supply (Delta Elektronika SM 120-50), gaussmeter, multimeter (Agilent 34411A) and PC with special code for voltage, current and resistance change measuring in magnetic field. In this case the electromagnet has exchangeable poles which surface area could be changed from 490 cm2 up to 20 cm2 and a distance between them from 10 cm up to 1 cm. Therefore, homogeneous magnetic field could be created between the poles.

 

Compact high magnetic field source
Compact high magnetic field source (pulse duration 0,5-1 ms, B up to 40 T) consists of capacitor bank high power switch and a pulsed coil. Discharging capacitor bank through pulsed coil a high magnetic pulse can be generated. Coil winding is insulated with Kapton® and reinforced by Zylon®-epoxy resin composite. Such construction allows to generate pulsed magnetic fields up to 40 T, 0,5-1 ms of half sinus shape pulses. Such facility is unique in Lithuania allowing to investigate materials in high pulsed magnetic field.

 

Electroporation of biological cells
It is two types of electroporation setups. First setup for electroporation of biological cells consists equipment for generation and registration of nanosecond-pulses. It allows generation of pulses with the amplitude of 2 kV and the duration of 15 ns - 1 μs.
The second setup for generation of high-voltage (up to 30 kV) 10-90 ns-duration pulses which is realized using a spark-gap discharge triggered by high-power subnanosecond (Standa, STA-01)laser.
