Description
  • Hall sensors offer an attractive true non-inductive method of magnetic field measurements for fusion reactors. However, there is only limited experience in using of these sensors in such demanding environment. Recently, a combined magnetic probe was developed for CASTOR tokamak, which contains 3 Hall sensors and 3 coils arranged to measure all three components of magnetic field approximately in a single point of space. The probe is compatible with in-vessel use well in confinement region of CASTOR. It is fully controlled by multi-functional electronic system. Design of the system and its implementation on CASTOR is reviewed. Results obtained using this diagnostic during various regimes of operation of CASTOR tokamak are presented. Radial profile of the poloidal magnetic field is used to deduce radial profile of safety factor.

  • Hallovy senzory nabízejí pro fúzní reaktory velmi zajímavou neinduktivní metodu měření magnetického pole, a to jak dynamického tak stacionárního. Prozatím jsou však malé zkušenosti s jejich používáním v tak náročném prostředí jakým plazma bezesporu je. Pro tokamak CASTOR byla vyvinuta kombinovaná magnetická sonda složená ze 3 Hallových senzorů a 3 cívek uspořádaných tak, abychom mohli měřit všechny složky magnetického pole téměř v jednom bodě uvnitř vakuové komory tokamaku. Soustava je plně řízena multifunkčním elektronickým systémem. Pozastavíme se nad jeho konstrukcí a začleněním do diagnostiky na CASTORu. Výsledky měření získané pro různé režimy chodu tokamaku CASTOR jsou porovnávány s průměrnými hodnotami získanými ze standartní diagnostiky. Z radiálního profilu poloidálního magnetického pole je vyvozen radiální profil faktoru zásoby stability. (cs)
