FEE--Octant Test Work

•St. 2 Production Chamber•6 readout planes•960 channels

•4 chassis, fully populated•8 Control Boards•16 Cathode Readout Cards

•12 channels of HV, dist. system•10 channels of LV, dist. system

M. Brooks


FEE--Octant Test Work•Mechanical Structures:

•Chassis and cross-rib assemblies delivered to BNL some time ago. Assembly mostly complete, by Andrew, some plumbing still needs to be received.

•Board Status:•First control board (3rd round) received (LANL) and checked out o.k.; Full order placed.•First Readout Card (3rd round) expected this week; full order will follow

•Noise specs already achieved on large fraction of the channels; this latest version should have layout fixes required to meet specs on all channels

•Backplanes expected 17-April•HV

•Initial hookup complete•Will switch to latest version of distribution system over the next couple of weeks

•LV•Distribution system design completed by LANL/UNM•First production board expected this month, also real LV supplies

•DAQ•Hookup to GTM, DCM, associated software completed by Ming, Jamie, Mickey

•ARCNet:•Preamp, AMU/ADC, FPGA downloads available (Andrew). Also, board monitoring (T, I, V)

•Calibration System•Already had gone through few rounds (Pat and Mike); final or nearly final system expected available for octant test

M. Brooks


FEE--Other Work•Ancillary Systems:

•Full review of system completed by Steve Pate, Andrew Hoover. Orders of necessary VME modules begun

•Mechanics (AMC @ NMSU, Jake and Bernie @ LANL)•In-magnet mechanical structures to nearly complete•Eyebrow (platform for racks) completed

UNM: Preamp testing nearly complete, LV distribution sent out, much work for FEE safety review completed by NickiFPGA: Download via ARCNet worked on by Andrew, full production FPGA code worked on by Jack FriedRack Layout completed, cable layout begun (Jan B.)
