B6 Oxford final sign-off check list

Barrel Check that all bolts and other mechanical fixings are glued in

place with loctite (a removable rad-

hard adhesive)

Not done

Verify that no loose objects are

inside the barrel/service cages.

Done

Service cages Check that all boxes are properly

secured and all screws are tight

inside the earthing ring. Check thatno loose DCS sensor cables are

hanging out of their slots.

Done

Harnesses Disconnect fibres, fit each MT12connector with protective cap and

carefully coil fibres in boxes,

taking care that nothing is sticking

out of the lid.

Done

Shorting cards are mounted on

TPPs with all connectors properly

attached.

Done

Check visually that all harnesses

are properly insulated from the

barrel structure (have kapton at theclamping at the barrel ends).

Not done (no problems found during testing)

DCS Check all temperature sensors for

swaps. If a swap is found the

sensors should be swapped in the

JST connector on the service cages.

No swaps on B6

Secure all screws on the cooling

temperature sensor clips with

Loctite. Make sure that the wires to

these sensors cannot touch any

modules. Glue down if necessary.

Not done

Publish calibrations for all sensors

on barrel on the web.

Not yet done

FSI Before shipping check that no FSI

ribbon has been damaged on the

spools during the assembly.

One fibre ribbon damaged at RAL

Cooling Close of all cooling loops at theend with Metrulok blanking pieces.Should we leave capillaries on?

Done. Capillaries left in place

Modules All modules have been electrically

tested (incl. HV). Test results arepublicly accessible.

Done

Check that no module connector is

exceeding the envelope of the

particular barrel.

Not done. No template available

3/4

Closing transport

boxes.

Install the ShockLogChange both batteries and only install at

the last moment. It has a 10-day life.

Once ShockLog is in place, avoid

knocks and bangs around the barrel (e.g.floor).

Done

Install roof panels first.Someone holds a gloved hand below each

corner piece when screw is inserted and

tightened in the upper part.

Done

Make sure that all ground straps are

properly connected.

Removed bottom straps to enable insertion into outer box

Secure brass inserts in corner

pieces with tape so that they cannot

fall into the container.

Secured with glue

Carry out final visual inspection

before service cage ends are closed.

Done

Mark one end of inner box with a

sign indicating Z (gearbox) end.

Not done. Gearbox end is coming out last out of outer container.

Wrap inner box Done

After installing inner box in outer,

check that inner box rails are fixed

into outer box saddles. (Screwsshould be M6 or bigger).

Done

Take care with installation of the

outer box panels. These were a

difficult fit on B3 and one mustavoid shocks to the barrel.

Nitrogen system, if used. Needs

documentation about the barrel is

passed on to CERN.
