To use both anydesk and firefox on the carme server require an internet connection.
As the server is on the cryring local network an ssh tunnel needs to be opened to the GSI proxy server.

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 |

|
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. |

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. |

|
Baking tent, frame and trays fully removed from CARME chamber. Removal of baking frame required removing air lines from upper gate valve and repositioning
of vacuum hose connecting turbo pump to backing line and turbo power cable. Some difficulty encountered removing upper baking frame now the target support
frame is assembled. Small modification seperating section in two would aid future installation and disammebly. |

Found SIP power unit for D2000 #4 not functioning correctly. Max current regardless of ion element connected to.
ML kindly loaned a spare. All D2000 work Ok now. Will have to send faulty unit for repairs back to SAES. |

Increased conditioning temperature in D2000 #3 and 4 (behind detectors) to 150C from 130/140C. No appreciable change in temperature. Minor effects in
pressure.
Pressure has completely recovered from yesterday and did not settle on higher/lower plateau value which may suggest conditioning the D2000 NEG |

Used thermocamera provided by GSI beam diagnostic division to take some pictures of YR09. See attached.
Due to aluminium outer wrapping some reflections are inevitable, but tried to only take pictures of heat spots that did not disapper from different
angles. |
