Hi Ernest,

Here at APS, we are extensively using PVA/EPICS 7 for various control aspects of APS/APSU accelerator.

Here are some highlights:

1. EPICS V4 for high performance DAQ for
   1. Fast feedback system;
   2. Power Supply data out of FPGA;
   3. BPM turn-by-turn data;
   4. LLRF;
   5. We have been using EPICS 4.6 + 3.15.4 for more than a year in production with our real beam and is working on updating to EPICS 7
2. pvaPy
   1. GUI, simulation, server, data analysis
3. Area detector with PVA plugins for beam diagnostics, which is with EPICS 7

Thanks,

Guobao
