Opis:
The Compact Muon Solenoid CMS is one of the major detectors of the LHC Large Hadron Collider accelerator. The second, a competitive brother, is Atlas. The accelerator complex in CERN was shut down for two years, after two years of exploitation, and will resume its work in 2015. During this break, called long shutdown LS1 a number of complex components, including electronics and photonics, will be intensely refurbished. Not only the LHC itself but also the booster components and detectors. In particular, the beam luminosity will be doubled, as well as the colliding beam energy. This means tenfold increase in the integrated luminosity over a year to 250fb⁻¹y. Discovery potential will be increased. This potential will be used for subsequent two years, with essentially no breaks, till the LS2 in 2017. The paper presents an introduction to the research area of the LHC and chosen aspects of the CMS detector modernization. The Warsaw CMS Group is involved in CMS construction, commissioning, maintenance and refurbishment, in particular for algorithms and hardware of the muon trigger. The Group consists of members form the following local research institutions, academic and governmental: IFD-UW, NCBJ- Świerk and ISE-WEITI-PW.

Opis:
High energy physics experiments require fast and efficient methods for reconstructing the tracks of charged particles. The commonly used algorithms are sequential and the required CPU power increases rapidly with the number of tracks. Neural networks can speed up the process due to their capability of modeling complex non-linear data dependencies and finding all tracks in parallel. In this paper, we describe the application of the deep neural network for reconstructing straight tracks in a toy two-dimensional model. It is planned to apply this method to the experimental data obtained by the MUonE experiment at CERN.

W artykule przedstawiono zagadnienie analizy warstwowego systemu zabezpieczeń z uwzględnieniem błędu człowieka-operatora. W analizie bezpieczeństwa funkcjonalnego systemów sterowania i zabezpieczeń istotną kwestią jest dokonanie redukcji ryzyka poprzez warstwy zabezpieczeniowo ochronne. W referacie przeanalizowano system składający się z trzech warstw: podstawowego systemu sterowania BPCS, systemu alarmowego AS oraz systemu automatyki zabezpieczeniowej SIS. W warstwowym systemie zabezpieczeniowym ważną funkcję spełnia system alarmowy, poprzez który człowiek-operator ma istotny wpływ na realizację funkcji bezpieczeństwa. Funkcje te są realizowane poprzez odpowiednie moduły w ramach systemu BPCS, lub SCADA.

Opis:
Wide scale, European, infrastructural research projects on accelerator science and technology are under realization since 2003. CARE project was realized during the period 2003/4-2008, and next EuCARD during 2009-2013. Now during 2014-2017 there is successfully continued EuCARD² - Enhanced European Coordination of Accelerator R&D. European accelerator R&D community prepares next continuation of the EuCARD inside the Horizon 2020. The paper presents the work developments of EuCARD. Several institutions from Poland are participating in EuCARD: NCNR in Świerk, IChTJ, technical Universites in Łódź, Wrocław and Warsaw. Realization of the project during the last 12 years gave numerable and valuable results combined with essential modernization of the European research infrastructures. From the point of view of domestic interests, where we do not have large research infrastructures, the considerable benefits are associated with the participation of young researchers from Poland - engineers and physicists, in building of the top research infrastructures. Due to such participation, high technologies are developed in several centres in the country. The EuCARD project organizes annual meetings summarizing periodically the R&D advances. The EuCARD AM2015 was held in Barcelona in April.

Opis:
In this paper, a novel probabilistic tracking method is proposed. It combines two competing models: (i) a discriminative one for background classification; and (ii) a generative one as a track model. The model competition, along with a combinatorial data association, shows good signal and background noise separation. Furthermore, a stochastic and derivative-free method is used for parameter optimization by means of the Covariance Matrix Adaptation Evolutionary Strategy (CMA-ES). Finally, the applicability and performance of the particle trajectories reconstruction are shown. The algorithm is developed for NA61/SHINE data reconstruction purpose and therefore the method was tested on simulation data of the NA61/SHINE experiment.

Opis:
Human error is recognized as the most common factor that causes maritime accidents. The human error assessment and reduction technique (HEART) is a human reliability assessment (HRA) that has been widely applied in various industries. Furthermore, the HEART – 4M method has been proposed to assess maritime accidents. The HEART – 4M method can clearly define the relationship between man, machine, media, and management factors and the human error. However, the calculation process to determine the weight of every selected error-producing condition (EPC) suffers from the uncertainty of the assessor's estimation in practical applications, which may affect the objectivity of its result. In this study, a modification of the HEART – 4M method with the technique for order preference by similarity to ideal solution (TOPSIS) is proposed. TOPSIS is a multi-criteria decision making (MCDM) tool. This study aims to develop the HEART – 4M method to make it more comprehensive and objective when assessing maritime accidents. First, the parameter of the generic task is determined as in the conventional HEART method. Second, the causal factors are converted to the suitable EPC – 4M, and there are four classification factors for the 38 standard EPCs, which are divided into man, machine, media, and management factors. Third, the TOPSIS is applied to handle the problems of interdependencies and interaction among EPC – 4M and the uncertainty that exists in the assessor´s judgment. The proportion effect of each EPC – 4M is determined through TOPSIS by considering the correlation among EPC – 4M. Finally, thirteen collision data obtained from the National Transportation and Safety Committee of Indonesia are assessed to apply the proposed method.

Opis:
The paper describes Trigger and Data Acquisition (TRIDAQ) systems of accelerator experiments for High Energy Physics. The background for physics research comprises assumptions of the Standard Model theory with basic extensions. On this basis, a structure of particle detector system is described, with emphasis on the following functional blocks: Front-End Electronics, Trigger and DAQ systems. The described solutions are used in the LHC experiments: ATLAS, ALICE, CMS and LHCb. They are also used in other accelerator experiments. Data storage and processing functionality is divided into two hardware systems: Trigger and Data Acquisition, that are dependent on each other. High input data rate impose relevant choices for the architecture and parameters of both systems. The key parameters include detailed system structure and its overall latency. Trigger structure is defined by the physics requirements and the storage capability of DAQ system. Both systems are designed to achieve the highest possible space and time resolution for particle detection. Trigger references are reviewed [1]–[39] as well as chosen accelerator research efforts originating in this country [40]–[83].

Opis:
The High Energy Physics (HEP) experiments, due to their large scale, required performance and precision, have to be controlled by complex, distributed control systems. The systems are responsible for processing thousands of signals from various sensors of different types. Very often, one of the data sources applied in such systems are visible light/infrared cameras or other imaging sensors, which provide substantial information about studied phenomena. High data throughput for camera systems require dedicated mechanisms for data collecting and processing. Moreover, the images from cameras should be also available to system operator. It needs the support from both operator panels interface and control application which should provide data in the dedicated format. The paper presents two different approaches to image distribution, processing and visualisation applied in distributed control systems. Discussed is the issue of support for cameras and image data implemented in the Distributed Object Oriented Control System (DOOCS) and an example control system designed to the needs of image acquisition system on the base of the Experimental Physics and Industrial Control System (EPICS) environment.
