Plasma surface coating equipment 

Radiofrequency glow discharge system (RFGD)

The RFGD is an in-house made equipment consisting of a large Pyrex tube reactor (50 cm length, 13 cm diameter) with copper electrode placed on the outside of the tube. The radiofrequency power (13.56 MHz) is supplied to the electrodes by an ENI Power Systems Generator (Model ACG 3XL) through a matching network (RFC 5MW) to minimize the reflected power. An Alcatel vacuum pump is used to obtain the required vacuum measured by an MKS Baratron. Gases can be introduced into the reactor trough special valves connected to an MKS 4-channel readout. 

The RFGD system is used mainly for modification of polymer surfaces for various biomedical applications.
