Assembly of the OH2L coax is now well underway. The operations remaining
include bending, vacuum impregnation, and fitup to the OH2L coil terminal
block. The feltmetal sandwich material used between the coax and terminal
components is now being produced at a rapid pace. Finally, components
for the OH1 and OH2U coax are being completed. Only the the OH2L
coax is on the machine assembly 'critical path'.

The upgraded power supply for the third ICRF transmitter has
arrived and is in position. This system, along with a fourth system
still requiring modification, will be used to drive the PPPL antenna.

Some minor changes to the cryo system have been made. The flapper
valve that regulates cryostat pressure by controlling the GN2 flow
through the bus tunnel has been replaced. The old valve was subject
to icing on its bearing surfaces. We have also moved all the
pressure transducers used to monitor nitrogen pressure in the
coils to an easy to reach position, away from the control valves.
This change should make the pressure readings more reliable.

Miklos Porkolab and Paul Bonoli were at PPPL this week for a
meeting on ITER RF. Earl Marmar and Jim Irby were also at PPPL for
a meeting on ITER diagnostics.
