Roméo Bonnefoy and François VazeilleTilecal Operation and Maintenance weekly meeting

CERN (4 July 2013)

Status

Production made by Proto Process (Evian, France).¨ 350 active Dividers produced and delivered.¨ Certification made at Clermont-Ferrand and started - Operators: Roméo Bonnefoy, Fabrice Podlyski, Timothée Theveneaux-Pelzer.

- Many Dividers rejected (see next slides).¨ 50 certified Dividers and QC delivered at CERN yesterday.¨ Other Dividers will be delivered in several steps.

Certification and Quality Control sheet

Test Bench of batch of 10 Dividersat 1 kV

Tests of voltages:Nominal voltage sharing

Measures without currentPercentages/nominal without currentPercentages with current/without current

Tests of capacitors

Tests of 10 resistor

Test duration: 20 minutes (automatically)+ 5 minutes (10 ) + 10 minutes handling 2

QC resultsÞ A lot of Dividers are rejected,mainly at the level of the HV cable.

Diagnosis %

Electric arc on the cable 3

Too short HV cable (-1 cm) 61

Too much bended cable 45

Good Divider 21

¨ A given base can cumulate several defaults.¨ 79% of cables are not OK.

Next actions¨ A specialized Cie will redo the cables.¨ Proto Process will put them.¨ Clermont-Fd team will certify again.
