Paul Derwent 8 Adding Applications o Actively adding applications:  3rd index page  Shot setup: »Beam line tuning »Diagnostics and monitoring  Stacking & operation: »Debuncher tuning »Accumulator tuning  New hardware: »VSA »Scopes »NMR probes P34TWT Status Page P101Flux Capacitor P142VSA Acc Long Prof P146Debuncher Bumps P152Deb Inj TBT P170Accumulator Ramp P188GPIB Command Editor P192Core Sig Suppression P194Proton Torpedo P207Long Emit Calc A CUTOFF DATE: After x/y/200z, no longer accept new applications? Force development of Java applications? Some recent programs

9. Paul Derwent 9 Future Applications o Pbar will be changing operational modes significantly as the Run II upgrades go forward:  Higher stacking rates  Frequent pbar transfers  Tuning needs will probably change »Using new hardware (e.g., VSA to do Debuncher TBT injection) »Developing new measurements (e.g., Debuncher momentum notch filter position) o Need structures (objects?) to make it easy for programmers to:  Setup hardware  Get data from hardware »Programmable scopes »Spectrum and signal analyzers »Programmable multiplexers  e.g., AP1 Gap Monitor and Scope »P194 120 GeV protons on target Measures important for Debuncher momentum cooling »P207 8 GeV pbars to MI Measures important for coalescing »Different timing and scales  J Budlong developing Java classes for the Tek scopes that are proliferating
