IFR Protocol Board

FEE crate

(Designed by S.Minutoli and M.Negri)

The FEE ( Front-End Electronic) crate contains the IFB, ICB, ITB and the ICC. The crate is a standard 6U VME crate from mechanical point of view, with the special IFR backplane ( PDB ). The ICC acts as a crate controller with the responsability to collect data from IFB, ICB and ITB and send them to the ROM via G_link.

The crate power supply and the temperature inside are monitored by a microcontroller in the ICC. Monitor data are send to Detector Control main system via CAN bus.

In the IFR data acquisition system there are 8 FEE crates, 4 for barrel and 1 for each endcap half-door.
