Query: Status Report on the Low-Energy Demonstration Accelerator (LEDA)   The 75-keV injector and 6.7-MeV RFQ that comprise the first portion of the
cw, 100-mA proton linac for the accelerator production of tritium (APT) project
have been built and operated. The LEDA RFQ has been extensively tested for
pulsed and cw output-beam currents <=100 mA. Up to 2.2 MW of cw rf power from
the 350-MHz rf system is coupled into the RFQ, including 670 kW for the cw
proton beam. The emittance for a 93-mA pulsed RFQ output beam, as determined
from quadrupole-magnet-scan measurements, is ex x ey = 0.25 x 0.31 (pi mm
mrad)2 [rms normalized]. A follow-on experiment, to intentionally introduce and
measure beam halo on the RFQ output beam, is now being installed.
