- All 9 staves met the requirements and have been
accepted: 5 have been sent to CPPM for parylene coating, the last four
will be shipped during this week.
- The stave 4005 checked to a 16 bar crash test.
The Al tube alone was already @16bar tested.
- Test Procedure:
- GEOMETRY MEASUREMENTS
- THERMAL MEASUREMENTS UNDER 80.5 W, WITH
COOLING WATER FLOW
- 20 CYCLES 0-16 bar (RAMPED PRESSURE RISE)
- 2 HRS @ 16 bar CONSTANT PRESSURE
- 30 CYCLES (SUDDEN PRESSURE RISE)
- THERMAL MEASUREMENTS UNDER 80.5 W, WITH
COOLING WATER FLOW
- GEOMETRY MEASUREMENTS
- Results
- NO EXTERNAL EVIDENCE OF DAMAGE
- SIMILAR THERMAL BEHAVIOUR
(global Shift can be due to roughness of the measurement setup), SLIGHT
TEMPERATURE INCREASE, MORE SIGNIFICANT IN A WELL CONCENTRATED AREA
(LOCAL DAMAGE?)
- NO SIGNIFICANT CHANGE IN GEOMETRY
