Opis:
The main goal of this research was to develop antistatic polyethylene films with a surface resistance of ≤109 Ω. The research involved testing low density polyethylene/linear low density polyethylene (PE-LD/PELLD) filled with various amounts of expanded graphite EG 096. The samples were made by hot pressing and injection molding. Mechanical and electrical properties were tested. The research results show that samples with a content of 30% by weight of expanded graphite are characterized by good mechanical properties, e.g. Young’s modulus of the filled PE was higher by 195% compared to pure polyethylene.
Głównym celem prezentowanych badań było opracowanie antystatycznych folii polietylenowych o oporności powierzchniowej ≤109 Ω. W pracy zbadano polietylen małej gęstości (PE-LD/PE-LLD) napełniony różną ilością grafitu ekspandowanego EG 096. Próbki wykonano metodą prasowania na gorąco i formowania wtryskowego. Zbadano ich właściwości mechaniczne oraz elektryczne. Na podstawie wyników badań stwierdzono, że próbki o zawartości 30% mas. grafitu ekspandowanego charakteryzują się korzystnymi właściwościami mechanicznymi, np. moduł Younga napełnionego PE był o 195% większy niż polietylenu bez udziału napełniacza.

Opis:
Objective: the authors’ main objective was to analyse, on the basis of other publications on the subject, the merits, the stages and the reasons for which enterprises establish innovation-driven relationships, as well as to present the results of an empirical study showing the condition and scope of co-operation between Polish enterprises within the scope of innovation-related activities in the years 2017-2019. Project/methodology/approach: The results of the empirical study presented in the paper have been taken from a statistical analysis by the Central Statistical Office titled: “Innovative activities of enterprises in the years 2017-2019”, GUS (Central Statistical Office), Warsaw-Szczecin 2020. The study covering industrial and service enterprises was carried out in the years 2017-2019, and its results were published in 2020. The study applied the methodology developed by Eurostat and OECD described in the Oslo Manual (Oslo Manual, 2008). Findings: the paper and its summary discuss the main findings from the and the results of the empirical study conducted. Originality/value: the paper presents the latest data published by the Central Statistical Office, which are the results of studies innovation-focused activities of Polish enterprises as part of innovation-driven co-operation (relationships). The paper is addressed chiefly to industrial and service enterprises.

Opis:
A novel approach to a trigger mode in the Gas Electron Multiplier (GEM) detector readout system is presented. The system is already installed at WEST tokamak. The article briefly describes the architecture of the GEM detector and the measurement system. Currently the system can work in two trigger modes: Global Trigger and Local Trigger. All trigger processing blocks are parts of the Charge Signal Sequencer module which is responsible for transferring data to the PC. Therefore, the article presents structure of the Sequencer with details about basic blocks, theirs functionality and output data configuration. The Sequencer with the trigger algorithms is implemented in an FPGA chip from Xilinx. Global Trigger, which is a default mode for the system, is not efficient and has limitations due to storing much data without any information. Local trigger which is under tests, removes data redundancy and is constructed to send only valid data, but the rest of the software, especially on the PC side, is still under development. Therefore authors propose the trigger mode which combines functionality of two existing modes. The proposed trigger, called Zero Suppression Trigger, is compatible with the existing interfaces of the PC software, but is also capable to verify and filter incoming signals and transfer only recognized events. The results of the implementation and simulation are presented.

Opis:
The validation of the measurements quality after on-site diagnostic system installation is necessary in order to provide reliable data and output results. This topic is often neglected or not discussed in detail regarding measurement systems. In the paper recently installed system for soft X-ray measurements is described in introduction. The system is based on multichannel GEM detector and the data is collected and sent in special format to PC unit for further postprocessing. The unique feature of the system is the ability to compute final data based on raw data only. The raw data is selected upon algorithms by FPGA units. The FPGAs are connected to the analog frontend of the system and able to register all of the signals and collect the useful data. The interface used for data streaming is PCIe Gen2 x4 for each FPGA, therefore high throughput of the system is ensured. The paper then discusses the properties of the installation environment of the system and basic functionality mode. New features are described, both in theoretical and practical approach. New modes correspond to the data quality monitoring features implemented for the system, that provide extra information to the postprocessing stage and final algorithms. In the article is described also additional mode to perform hardware simulation of signals in a tokamak-like environment using FPGAs. The summary describes the implemented features of the data quality monitoring features and additional modes of the system.

Opis:
The paper presents improvements of the developed system for hot plasma radiation measurement in the soft Xray range based on a Gas Electron Multiplier (GEM) detector. Scope of work consists of a new solution for handling hardware time-synchronization with tokamak systems needed for better synchronization with other diagnostics and measurement quality. The paper describes the support of new modes of triggering on PC-side. There are communication and data path overview in the system. The new API is described, which provide separate channels for data and control and is more robust than the earlier solution. Work concentrates on stability and usability improvements of the implemented device providing better usage for end-user.
