The length of the wire needed was estimated with the aid of a scale image of the detectors in the CARME chamber and foam model pieces. Wire length estimated
by simply cutting wire so that it 'fits' the scale model and by taking coordinates of the end points of the longest sections of wire needed on
the model and calculating a bezier curve to estimate wire length. Bezier curve calculated by inputting the endpoints of the wire and control points such |

Wed Nov 10 18:38:16 2021, RSS TD + ML OG AK NK, CARME wrapped in heating tape
|
Heating and electronic experts were in CRYRING and were unhappy with the damaged wire. Heaters were opened by OG, but no damage was found. It is suggested
to replace the entire wire and then get it approved by the concerned authority.
To avoid further delays, ML and TD agreed on heating tapes/wires covering the chamber. OG helped in wrapping the heating wire around. Tent is |

This morning the pressure was 4e-7 mbar. The bolts on the windows and the large flange on the bottom of the interaction chamber were tightend.
No leak was present on the windows following tightening. However, the leak on the rotatable flange, although decreased in magnitude, was still in the 1e-9 |

With the assistance of Oemer and Davide all of the M22 bolts removed from the downstream section of the CARME chamber. To separate the downstream section
from the
upstream sections it was necessary to use a lever between M10 bolts screwed into the lift points of adjacent sections of the CARME. The upstream sections |

Confirmed leak as per previous Elog.
Tightened to 100 Nm - no effects.
Tightened to 130 Nm - bottom leak disappeared. Top leak still at 1.3E-8 mbar l second. |

Mounted rails on dolly. The rails don't smoothly connect to those on the Aluminium frame and some thin metal shims were required to get the
correct height. A metal support had to be placed above the Delrin pads to support the rails above the gap between frames. |
