Komunikační protokol pro kontrolu polohy a tvaru plazmatu tokamaku COMPASS
Janky, F. ; Horáček, Jan ; Pereira, T.V.
The Compass tokamak, reinstalled at IPP Prague, will have a new digital plasma position and shape control system. Development of a communication protocol is necessary for the connection between the energetics devices built by CKD company and the operator - either human or computer together. The present work is focused on development of such communication protocol. Human operator can send a request for status of energetics, time synchronization, counting errors, etc. through communication protocol. Predefined currents for individual power supplies will be send through the communication protocol. In the future this system will be replaced by feedback control system integrated in CODAC (Control Data Acquisition and Communication system).

Vysokopovrchové hydrodesulfurizační katalyzátory MoO3/TiO2
Gulková, Daniela ; Kaluža, Luděk ; Vít, Zdeněk ; Horáček, Jan ; Macháčková, Eva ; Zdražil, Miroslav
MoO3/TiO2 were prepared by impregnation of TiO2 supports with surface areas of 140, 230 and 407 m2g-1. MoO3 loading was in the range 2-32wt.%. The point of zero charge of the supports was 5.0, 8.1 and 10.5, respectively, and decreased with MoO3 loading to the value for MoO3 (2.1). According to the point of zero charge the supports were saturated with a molybdena monolayer at approximately 12, 24 and 14 wt.%, respectively. Temperature-programmed reduction exhibited four peaks, which were assigned to the stepwise reduction (Mo6+ to Mo4+ to Mo0) of tetrahedral monolayer species, po

Analýza relaxačních jevů v tokamaku CASTOR vyvolaných nabíjením okrajového plazmatu hluboce vnořenou elektrodou
Brotánková, Jana ; Stöckel, Jan ; Hron, Martin ; Štěpán, Michal ; Peterka, Matěj ; Horáček, Jan ; Ďuran, Ivan ; Spolaore, M. ; Peleman, P.
Transport of plasma to the walls is one of the crucial topics in magnetic confinement fusion research. In tokamak CASTOR, during special regimes with strong biasing of plasma, we can observe relaxation events, corresponding to increasing and collapsing of a transport barrier. High spatially and temporally resoluted arrays of probes enable us to describe these phenomena in details.
