v3.0 RF Cabinet
IntermediatePowerAmplifier
Final PowerAmplifier
RF ControllerNew Firmware
§ More rapid resonance searching§ Faster recovery from crowbars§ Text error messages aids diagnostics§ Tracks operating hours of final amp
Combined Digital MeterDisplay
§ Eliminates noise seen on analog meters. More accurate, less likely to fail§ Flexible – get more information to aid troubleshooting
Pallet Amplifier § Increased power pallet amplifier (500 W to 1 kW) to increase reliabilityCombined Digital MeterDisplay
§ Eliminates noise seen on analog meters. More accurate, less likely to fail§ Flexible – get more information to aid troubleshooting
Higher Power § 800 W capacity gives more head room to drive final amp (improved reliability)
Eliminate matchingnetwork
§ Makes two tuning controls redundant hence simplifies setup / reduces service complexity (requires new matched50W final)
Indexed tuning § Easier tuning due to ability to record current setting and turn up/down in known increments
50W Final Input § Directly matches IPA input, eliminating need to tune IPA matching network, simplifying setup
Increased structuralstrength
§ Reduce failure rate of electrical components currently seen due to mechanical stress, e.g. failures of solder joints§ Reduce shipping damage by replacing fragile components such as Ultem standoffs
Increase output to 12kW
§ Increase from 10 to 12 kW§ Increased head room, hence less stress on system and fewer failures
High voltage powersupply § Increased output to support higher-output final amplifier
Breaker Panel PCB § Updated components to improve reliability
Input circuit breaker § Increased rating to reduce unnecessary trip events

Eclipse Technology Focus Areas
The critical areas being addressed to increase the performance and sustainablity of the Eclipse:
• Improved beam dynamics and injector output: Reduce the beam losses from the source into thefield of acceleration and improve beam dynamics
• Higher power and modern RF system: 12kW v3.0 RF system to be released
• Improved conditions for beam acceleration: Higher vacuum (10^-8 Torr) and improved heat transferfrom the dees
• 18F target saturation yield: Opportunities to increase saturation yield in process of being optimized

Testing Changes to 18F HP TargetRemoval of hex grid gives ~5% increase saturation yield
• Current design uses a copper nose piece with hexgrid for Arnavar window support• Hex grid prevents major window failure but
copper gets highly activated which increasesexposure when rebuilding target
• Testing ongoing using Aluminum nose piecewithout hex grid• Aluminum doesn't get activated, but higher risk
of window failure causing distribution of activityand activated Arnavar material withincyclotron– avoided by diligent PM schedule
