Abstract
A significant upgrade to the 110 GHz DIII-D ECH system was begun in 2005. Two short pulse (< 2 s) GYCOM gyrotrons were replaced by CPI diode gyrotrons having acceptance parameters of 1.0 MW, 5 s and designed pulse length of 10 s. In addition, a CPI gyrotron with depressed collector, which has demonstrated 1.3 MW for short pulses, was installed and is being tested. Two CPI gyrotrons, which have experienced collector failures, are being repaired.
