Mezzanine manufacture Progress • • 10 th November 2009 PCB design sent to manufacturer

Mezzanine manufacture Progress • • 10 th November 2009 PCB design sent to manufacturer Order for assembly placed and parts purchase started. PCB manufacture error requires restarting the build. Expect PCB this week. Assembler planning sequence broken – hard to predict delivery until pcb arrives. Two of the failed pcbs delivered to use for mechanical checks. ERNI connector mounted – pcb too large – manufacturer will change by 1 mm overall Plan to send one pcb to wirebond engineers.

FEE 64 testing and VHDL progress • • • Assembled boards delivered. Power supplies

FEE 64 testing and VHDL progress • • • Assembled boards delivered. Power supplies tested and found to be working OK after a couple of wire mods. FPGA programmed through JTAG port. Two misplaced devices removed and re-fitted Flash memory programmed and used to program the FPGA. 10 th November 2009

FEE 64 testing and VHDL progress • • • 128 MB SDRAM operating successfully

FEE 64 testing and VHDL progress • • • 128 MB SDRAM operating successfully Gbit ethernet functions at 10/1000 Mbits/s Linux loaded over the network after the core loaded by JTAG. Loading from Flash memory not functioning yet. Some ethernet problems solved by damping capacitor. Ethernet rate tests => 10 MB/sec Started testing the multiplex readout ADC. First results using MIDAS and TCL scripts. 100 m. V input via the test mezzanine. VHDL for timestamped ASIC driven operation in progress. 10 th November 2009 400 300 200 100 0 29517 29567 29617

Trial mechanical assembly Plastic versions of the FEE mechanics created by a ‘Z’ printer.

Trial mechanical assembly Plastic versions of the FEE mechanics created by a ‘Z’ printer. Two FEE 64 cards and two mezzanine scrap boards assembled. Some alterations to the spacer required. 10 th November 2009
