 | The overall tube process is described in the FCal1 process sheet 1.3.3.1.1. Another overview on the sequence of procedures in the tube process is given in the FCal1 Tube Process Workflow Diagram. This diagram can also be used to navigate through the various process sheets. The order of processes in the two groups 1.3.3.1.1.1 and 1.3.3.1.1.2 in the listings below is also following the sequence of application. |
|
1.3.3.1.1.1 |
| The tube acceptance process is performed for a random sample of 200 tubes extracted from the shipment. The procedure is described in process 1.3.3.1.1.1, which includes the two processes 1.3.3.1.1.1-1 and 1.3.3.1.1.2-1 (see links below). | ||||||||
|
1.3.3.1.1.2-1 |
| The visual tube inspection is part of the regular tube processing described in 1.3.3.1.1.2, and has also been performed for the randomly sampled 200 tubes. |
|
1.3.3.1.1.1-1 |
|
The inner and outer radius of each of the 200 sampled tubes has been measured as described in
the process 1.3.3.1.1.1-1. The results are summarized
in the |
||||
|
1.3.3.1.1.2 |
| This process describes the "normal" procedures applied to prepare the tubes for installation into the FCal1 copper matrix. | ||||||||
|
|
1.3.3.1.1.2-1 |
| Each tube is subjected to a visual and rolling inspection after unpacking from the crate, as described in this process sheet 1.3.3.1.1.2-1. Typical batches of 1000 tubes are inspected at a time. | ||||||||
|
1.3.3.1.1.2-2 |
| The two ends of each tube are de-burred after the visual and rolling inspection described in the process sheet 1.3.3.1.1.2-1. | ||||||||
|
1.3.3.1.1.2-3 |
| Visual inspection of the de-burred tube ends (process 1.3.3.1.1.2-2). Tubes can be rejected following the guidelines given in this process sheet 1.3.3.1.1.2-3. | ||||||||
|
1.3.3.1.1.2-4 |
| The tube cleaning process is a sequence of soaking, ultrasonic excitation, agitation and rinsing of batches of tubes in various chemicals and water baths. The quality of the cleaning is checked in the following tube cleaning inspection (process sheet 1.3.3.1.1.2-5). | ||||||||
|
1.3.3.1.1.2-5 |
| The results of the tube cleaning are inspected and tube batches are either accepted for storage (see process sheet 1.3.3.1.1.2-6) or send back to the cleaning process 1.3.3.1.1.2-4. | ||||||||
|
1.3.3.1.1.2-6 |
| Tubes are packaged and stored after successful cleaning, for future use in the matrix assembly process 1.3.1.7). | ||||||||
