Business trip March 2015

Ing. Matej Oravec attended a business trip in CERN.

Part of the work consisted of creating a driver for the cooling device Hubert MiniChiller H1 plus and its connection with WINCC OA. The cooling device is connected to the PC via the RS232 serial interface. The device driver is implemented in C++ programming language (under OS Windows) and contains programmed communication with the device (writing data to the serial port and their encoding/decoding into a form understandable for the connected cooling device). The driver has also implemented DIM server functionality and sends data from the device to the visualization in WINCC. The visualization contains functions for controlling the cooling device from the PC.

The next part of the work consisted of creating communication between the card being developed, called the Readout Board (RB) and the WINCC OA tool. Communication was realized in C/C++ language (under OS SLC 6) with implemented DIM server functionality. The card is still in development and its functionality is still limited.

Business trip February 2015

Members of CMCT&II participated on business trip at CERN:

  • doc. Ing. Ján Jadlovský, CSc.
  • Ing. Matej Oravec
  • Ing. Ján Čabala

During their stay, they worked on the implementation of analytical and programming work in connection with the development of the new generation of Pixel detector. After consulting and coordinating consultations with project management headed by project manager Luciano Mousa, we determined the scope of work in detector development. Subsequently, we received data (electrical diagrams of the power supply of the detector, blocking and cooling system as well as data in connection with the connection of these modules to the DCS experiment ALICE).

Then we took over the available peripherals (new Huber cooling module, existing CAEN power supply). These peripherals were connected to a computer server with WINCC OA installed. During our stay a program interface for Huber cooling module was created and together with the CAEN power module the mentioned peripherals were logically and physically connected to DCS ALICE during our stay.

In this way, a workplace has been created which can also be operated via remote access.

In addition, discussions were held on HepTech’s activities and the joint conference „CERN’s amazing world and its research – become part of it“.
