improved.
• A full-sine-wave power supply

implemented.

Instruments and controls:
• A second power-amplifier loop
on the vertical transverse-feed-
back system was upgrated to
enhance the feedback power.
• EPICS (experimental physics and
industrial control system) control
interfaces for the injection wave-
form display were updated.
