Schedule

Following is the planned production schedule for barrel capillary production. As of this time, disk capillary production has been completed.

Production Progress

Barrel

The production tracking spreadsheet is updated frequently and may be found here. Representative weights of the capillaries are here. Not all capillaries will be weighed. Uniformity is good enough to not need this.

Disk

Capillaries for both endcaps have been completed. 24 (12 per endcap) good capillaries were produced with no spares (spares will be produced on demand if a failure occurs later in the integration). The production tracking spreadsheet may also be found here. The weights are here.

Repairs

The items linked in this section describe repair procedures for the capillaries.

Development of a splice repair for a disk capillary may be found in the folder here.
