1. 16-Oct-15S.Movchan Straw manufacturing and QC1 Straw machine status polished anvil new welding configuration software for on-line seam quality control status conclusion DB, Dubna assembly hall Presented by S.Movchan

2. 16-Oct-15S.Movchan Straw manufacturing and QC2 CERN polished anvil Ra=0.04 mkm Rz=0.33 mkm

3. 16-Oct-15S.Movchan Straw manufacturing and QC3 New fixture Tape -> to straw shape

4. 16-Oct-15S.Movchan Straw manufacturing and QC4 New welding configuration

5. 16-Oct-15S.Movchan Straw manufacturing and QC5 Seam shape on-line QC by microscope set up weld seam shape

6. 16-Oct-15S.Movchan Straw manufacturing and QC6 Software: seam quality on-line control Set of pictures processing Modes: - manual - auto (0.8 sec per frame) Tuning cut level: typical – 0.02

7. 16-Oct-15S.Movchan Straw manufacturing and QC7 Straw machine: conclusion Ready: Straw transportation mechanics: - forward speed – (4-22) mm/sec - reverse speed – 22 mm/sec Room T and H control – ready Ultrasonic generator control – ready In progress: On-line QC by microscope Clean room start up In fabrication: Tape pretension mechanics Tape to round shape transfer: set of fixtures - ready Light source for on-line microscope Preparation: Set up for serial straw test at dP=3 bar Straw bar code printing

8. 16-Oct-15S.Movchan Straw manufacturing and QC8 Straw machine: conclusion Design: Tencile machine – done Storage box for serial straws - option 1 Set of “nipples” for straw long term storage Set up for straw filling by gas: dP=1.2 bar Straw boxes depository inside the clean room Checker pressure inside filling straw during it storage Problem: Electrostatic charge of tape – due to this effect straw transportation speed is non stable. Shuttle speed is constant. => Straw – elastic body.

11. 16-Oct-15S.Movchan Straw manufacturing and QC11 Straw labeling: label glue to straw

12. 16-Oct-15S.Movchan Straw manufacturing and QC12 Straw labeling: conclusion Straw labeling procedure is proposed: - label code - 62TSJIN0999999 (14 digits) - label size – 10x30 mm - print labels by “label printer” - 2 the same labels will be glued on both straw ends (for robustness) - before straw gluing into module straw label will be read out and cut out - straw # (label) will be replaced by hole # in the “Module holes numbering DB” Label reader and DB (based on Excel table) exist at Dubna
