Software: seam quality on-line control
Each seam photo size is about8x10 mm2 at zoom x16 and straw production speed of V=9 mm/sec. So we have some frame overlapping of neighbor Photos.
File record – set of about 250 .bmp photos
File processing: - modes: - manual - auto (0.8 sec per frame)-good/bad seam alarm level: - typical is 0.05

Weld line needs more work before becoming fully operational.
PET research and development appears to be coming to an end.
We have solutions JINR / CERN for storage under pressure.
We should target a start date for full production in September 2010

•Manufacturing end plugs is necessary for long term leakage test of the straw in storage time under pressure•One of two end plug should be possibly inside of the straw for easy mounting because overpressure in the straw is useful for mounting straw to frame
Was tested three types of end plugs which may be used in different combinationAll of them seems to be suitableFinal choice will be complete with sufficient production statistic

ConclusionConclusionEnd plugs filled in cap:
+ seems to be reliable compacting- need high room for vertical polymerizations- need additional cutting operation
End plug filled on silicone:+ inside of the straw (low diameter)- need high room for vertical polymerizations - compacting depend on adhesion
End plug glued to straw:+ There is possibility easy adjust pressure in the straw- Need mechanical treatment- High weight and cost
