Wed Jan 12 20:07:20 2022, JM, OH, TD, FEE holder installation 10x
|
4 FEE holders installed on CARME. Mounting procedure devised due to limited working space to install.
Mounting procedure:
>Install FEE holder mounts (image 1) onto feedthrough flange |

Thu Jan 13 10:33:24 2022, JM, OH, TD, Adaptor Board misallignment
|
The ERNI connector is not central on the adaptor boards causing misallignment with the FEE.
The adaptor board is 80mm long. The ERNI connector is 50mm long. The connector is 13mm from the 2x Lemo side and 17mm from the 3x Lemo side.
This results in misallignment between the FEE and adaptor board. |

Sat Jan 15 15:38:25 2022, JM, OH, TD, FEE installation, cable management
|
All 8 FEEs have been installed in their holders.
The damaged feedthrough does not have the D-connector on the adaptor board inserted into the falnge but the FEE is connected to the adaptor board.
FEE's were carefully installed, with one person inserting FEE and another making sure FEE was straight and on the correct pin positions. |

Wed Jan 26 19:16:18 2022, JM, OH, Water cooling, FEE MAC address
|
Water cooling has been connected to the FEE's. Flow meter installed to outlet manifold by way of two right angled pieces. No leaks observed
rom any points in the coolant loop, loop will be bled using taps tomorrow. Water turned OFF overnight.
FEE's powered up with the MAC addresses of each read. 1 is the very bottom FEE and 8 the very top. FEE's have also labelled with the |

Power, Ethernet and HDMI cables connected to FEEs. To prevent cables coming out of connectors, power and HDMI cables are zip tied to FEE cooling pipe
(see attached image).
Correct FEE MAC addresses have been updated in /etc/dhcp/dhcpd.conf |

|
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.
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 |

Pulser walkthrough taken for motor position 23.1mm and motor position 67.43mm.
Points taken at 30,50,70,90,110,130,150,170,190,210,230 for 23.1mm position and 230,210,190,170,150,130,110 for 67.43mm position.
Motors moved to fully OUT position and pin put back in. Current positions before closing program 19.1mm and 19.57mm. |
