NEW NEW NEW - adapter cable for linking forward hybrids to barrel support cards
fwdadapt.ps,file showing adapter cable, barrel support card and forward module.
OLD Hybrid, proposed forward opto and power cable pin assignments. The pin assignments here are designed so that the interconnecting, two-layer, kapton cable can be made without crossovers or the need for plating through. This will allow this cable to be made from two layers of aluminium on kapton.

To understand use of layer names see pltabc1a.mac, this is a text format macro file used for producing plots from the PCAD database and contains all the layer names, their use in the database and the groupings of layers for plot production There are many layers in the database other than those used for plot production, containing mechanical info, layer buildup etc. Please understand that this database file has evolved over time and several different pcb and hybrid designs so it contains information on some layers that may not be up to date or relevant.

scha0.dxf, dxf file of full schematic which if plotted at A1 size will give readable text if the plot is good.
scha0.ps, postscript file of whole schematic - but too small to read unless you can enlarge it so there now follow 16 A4 size sheets which can be put together to form an A0 plot if you have no other option

NEXT FORWARD HYBRID _ PROVISIONAL PLOTS FOR DISCUSSION
original and proposed increased cooling contact area on forward hybrids.
NOTE that the new increased area is close to the maximum possible using the original V1 hybrid profile. This has been achieved by removing all diagnostic lines and removing the bus and resistors required for distribution of the CAFE current setting line. If these are required then this new contact area will have to be reduced.

Some plots of the component overlay etc. of the cdp/lbic/cafe/hac forward hybrid. Note that the schematic and component assignments are essentially the same as the original Carl Haber barrel version A single sided version was also produced on alumina using only the top side plots.
