7. Cavity Controller - RF test stand
Cavity combiner
Prototype V1 under test (1x)
Cables received for 1 cavity (time of flight compensation)
1 combiner per section => 3 needed for test stand
V2 series (4x) will be launched by end of Sept.
Will be ready for installation (1 cavity) by December 2017
Mechanical support to be designed (BE-RF-PM ?)

8. Cavity Controller - RF test stand
Cavity controller (uTCA)
Hardware ready (uTCA: CPU, MCH, RTM (DS8VM1), AMC (SIS8300))
Europa crate
Predriver: production launched
RF calibration (filtering, attenuation, …): to be developed
Firmware
BE-CO will provide the infrastructure by end Sept (PCIe bridge, White-rabbit core, interfaces (SPI,…), DDR interface)
BE-RF is developing the RF feedback (1-turn feedback, polar loop, demodulator, modulator, …)
Software
Driver: Encore for PCIe/PCI under dev. By BE-CO (by end 2017)
FESA class (wait for Encore or use BE-CO internal library -UAL)
