Grounding

Ground cables have been daisy chained together from FEE to FEE. Ground cables are screwed into a feee bolt hole on the FEE body using an M3 bolt.&nbsp;

LEMO cables have been connected in a similar way between the grounds on the adaptor boards for each FEE. Short LEMO cables go between J6 on pairs of adaptor boards in the same FEE holder and long LEMO cables go between J7 on adaptor boards in different FEE holders.&nbsp;

The LEMO grounds from the adaptor boards and the ground cables&nbsp;attached to the FEE bodies are then connected together and then connected to the CRYRING grounding cable.&nbsp;

Pulser

Jan has kindly lent us a pulser. We send the pulser to an inverter giving us a +ve and -ve signal.&nbsp;

The +ve signal goes into the pn FEEs (1,2,5,6)

The&nbsp;-ve signal goes into the nn FEEs (3,4,78)

LEMO cable connecting FEEs in the same holder using J3 on adaptor board. J4 is used for recieving the pulse signal, connecting FEEs in different holders or terminating the signal.&nbsp;
