<p>(Fri 29 October)</p> <p>Cleaned wire seal recess and labeled thermocouples and flanges to identify p-n vs. n-n side and ports with bias pin. See attached in case baking damages the label.</p> <p>Grossmontage insisted to clean wire seal once more to remove black stains noticed when opening. Kapton vapour condensation could be possible cause. They used special cleaning product from XHV (not sure what - acetone mix with something?)</p> <p>Lifted CARME back. Inserted wire seal. Closed chamber. Step is noted between central CARME section and other two - it's normal. Noted some damage to SS vessel on the outside. Unclear what could have caused it but it's only cosmetic.</p> <p>Wire seal tightened with 20 - 40 - 60 - 80 - 80 Nm turns starting from top and proceeding in a circle. Had to temporarily dismount on foot to make space for torque wrench. Also had to saw off front part of ratchet attachmnent to slide wrench between GSI ion pump and flange. All other flanges closed by Grossmontage. Pump down started.</p>
