  116   Mon Oct 11 11:24:16 2021 RSS TD MLValve support and cable labeling

Split funnels were given to Oemer for cleaning. Have received them back after lunch.

Valve support is installed again (see picture 1).

Ion pump was connected but not activated. Michael will help in doing so. No vacuum support to help will RGA. Will proceed without it.

Neg and ion cables were labeled (see pictures 2 and 3).

Chamber was vented using nitrogen.

 

  117   Tue Oct 12 09:22:37 2021 RSS TD + OG DRMotors problem solved

Neg and ion cables were taken off and were put in the box.

Top support was taken off.

Motors are rotating again. Have to be careful with the position of the limit switches.

Split funnels installed on 4 (of 8) 2x78 way D connector feed-throughs.

  150   Wed Nov 10 18:38:16 2021 RSS TD + ML OG AK NKCARME 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 to be built by tomorrow.

MG and RSS tried the magnetic power back off thing which eventually did not work.

AK and NK helped with the power and thermocouple of the heating wire. NK has also covered the pipe and bellows near the magnet with heating jackets.

Ring seal is out. See picture 1.

Bellow (towards CARME) was installed in the gas jet chamber. Attached are some pictures.

  120   Wed Oct 13 12:06:09 2021 RSS TDFlanges cleaned
RSS & TD had some success cleaning the COF600 flange surfaces of the staining and residues observed when the downstream COF600 section was opened yesterday  
https://elog.ph.ed.ac.uk/CARME/118

Isopropanol and laboratory tissues were used - most but not all of the staining and the residues were removed.

  154   Fri Nov 12 08:54:11 2021 RSS ML + CB (remotely) NK AK NPFirst CARME baking attempt

07:50 Small leaks (near the motors and upper valve) were detected in the tent which were covered with Al foil.

08:10 ML changed the baking temperature to 120 degrees.

09:40 Since the bottom of CARME is cold, due to uneven distribution of heat, baking is stopped.

13:00 Tent was slightly opened from the sides so that the heat can escape.

13:15 NK mounted three 200 W (see red labels in the picture below) and one 40 W (see the yellow label in the picture below) heating jacket on four CF100 flanges. Power cables and thermocouples were taken care of by AK.

14:00 Tent was closed.

14:00-17:00 ML started baking at temperature 80 degrees to check the heat distribution in the tent. Baking was then stopped and will start from Monday.

Attached - thermocouple temperatures (now correct)
