Abstract
Jabba was offline due to an internal water leak destroying the main power and signal pass-through PCBs at the rear of the spectrometer. Repairs were completed, including new PCBs and cabling, to bring Jabba back online. The aft starboard Peltier-effect thermoelectric coolers were replaced. Mark-V and Jabba were removed from the mount. Mark-V has been moved into storage, and Jabba reinstalled in the electronics area at the rear of the dome fed by an optical fibre where it no longer requires water cooling. Additional repair work was completed to the mount RA drive transmission including replacing the stepper motor and gearbox, and also replacing the RA potentiometer encoder and signal cable. A new UPS was installed. Ongoing issues with the fibre conversion require further work.
