The detector controller (see Fig. 5) used by EMIR is based on a Generation III Leach Controller. Some modifications have been introduced to make it more robust. The boards have been interconnected using a flex-rigid circuit. Also a direct connection is made to the cryostat vacuum sealed connector with no cable.
Some boards have been adapted, which is the case of the slew rate of the clock signals, the analog chain previous to the A/D conversion, etc., to match with the characteristics of the detector.
The controller consists of:
• 4 video boards with 8 channels each,
• 1 back panel with power board,
• Rigid flex interconnection with additional electronics to achieve high slew rates for the pixel clock, and
• Fan and water cooled system to allow installation in a hermetic enclosure.
