A 1 GSPS VME data acquisition module
Loureiro, C. F. M.; Combo, A. M. C. F.; Correia, C. M. B. A.; Varela, P.; Manso, M. E.; Varandas, C.; Serra, F.In the following a new data acquisition architecture is proposed allowing high sampling rates along with a large memory data buffer. The modular design allows up to four 250 MHz, 8-bit acquisition channels to operate in an interleaved way, achieving 1 GSPS. Each channel can acquire continuously up to 3 MBytes of data (or 12 MBytes when interleaved). Since several modules can coexist in an acquisition system, pr...
Reflectometry measurements of the m=1 satellite mode in L- and H-mode plamas in...
Serra, F.; Manso, M. E.; Silva, A.; Matias, José; Wagner, F.; Zohm, H.; Kallenbach, A.; Varela, P.In ASDEX, with strong NB, heating, often a large central m=1, n=1 mode is observed on the SXR emission. For PNBI > 1 MW a mode rotating with the same frequency, the so-called`m=1 satellite`, is seen on the magnetic pick-up coils in the L and H-phases. Magnetic measurement s in the divertor chamber suggest that the satellite mode might be located outside the separatix, on open field lines reaching the diretor /1...
