TJ-II has an AM reflectometer [1] for measuring electron density profiles with a temporal resolution of 2 ms (located between sectors A4 and A5).
Apart from that, a fast frequency hopping reflectometer [2] was used from 2004 - 2008 in perpendicular incidence (conventional reflectometry) [3] . Since February 2009, the frequency hopping system is in operation in oblique incidence (Doppler reflectometry) [4], measuring plasma density fluctuation velocities and their wave number spectra.
