Project description:

The project aims to improve the technology used in the production of a new type of micro pattern gaseous detectors (MPGD). These gas ionisation detectors consist of microelectronic structures in which the distance between the anode and cathode electrodes is in the order of millimeters or parts of millimeters. The ionizing radiation particles interacting with the gaseous medium of such a detector generate electrons and ions, which are accelerated in an electrostatic field. By selecting the appropriate electrostatic field strength, it is possible to ensure an avalanche process of charge multiplication and thus to record the ionization event using an appropriate electronic circuit. Moreover, with the use of position-sensitive detectors, these solutions also allow process imaging.
The aim of the research is to develop a laser technology for the formation of polyimide (Kapton®) – diamond carbon (DLC) based microstructures, which is compatible with the technologies of gas electron multipliers (GEM) used in the high-gain Fast Timing MPGD (FTM) detector.
Project objectives:
1. To form mechanically stable, high adhesion, controlled electrically conductive diamond like carbon and nanocomposite diamond carbon based coatings on commercial polyimide films suitable for gas electron multiplier (GEM) technology.
2. To select the parameters of femtosecond laser exposure including wavelengths, energy densities and beam focusing and scanning strategies for the realization of microstructures used in GEM technology in the DLC-polyimide system.
3. To evaluate, together with CERN scientists, the suitability of the developed structures for GEM technology and high-gain Fast Timing MPGD (FTM) detector.
