Half Rung Up
We will have to machine these from the current half up types if
they have been made in sufficient numbers we need 8 or 9

These may well have been made already we need 8 or 9

Voltage solution
For columns close to top of crate
HV power out of column
with minimum of bending
Other Cables can make
S bend reasonably easily

Si Bias
Voltage solution
For columns far from the top of crate
All cables can exit form the
back of the column if there is
the space available
This also allows the voltage
patch panel to be in line with
the cable port in the shield
Low Voltage Power
Low Voltage Sense
Two 2 pin lemo cables – with approximately cat5 thickness and stiffness
High Voltage Power
Have to redesign end piece to allow these very thick cables to exit column
satisfactorily. Can unbolt from patch panel and feed through so not too much
compliance required.
HV monitoring
Goes to one 15pin sub D – may be a problem with
different lengths of cables
Silicon Bias
A single lemo cable – Can it come from the C board?
SPECS/ECS
Single RJ45 Network Cable
Temperature
Monitoring
Flat cable going to 37pin Sub-D
Data Fibres
24 Fibres going to 2 break out boxes. Need to be careful of
bending just after boxes. Need to be very careful of loop. Spare
fibres go down front U channel by HPDs.
Concerned about space for loop before patch panel.
Doesn't show looping round the Lo boards to use uip fibre length
TTC Fibres
7 TTC control fibres – occupying the same space as the data
fibres. Loop could be sooner to avoid too much conflict as no
break out boxes to worry about.
