Title: UCSB 4-Hybrid Thermal Test System Status


1
UCSB 4-Hybrid Thermal Test System Status
28 July 2003 Sam Burke UCSB HEP Group
2
Progress
  • Dry Air Bubbler arrived
  • Ordered replacement low air flow sensor
  • Work on 4Hybrid Test Procedure
  • Test Time estimated at 57 minutes

3
Cold Box System
4
Progress
  • Cooling Rate Study
  • Chiller water temperature
  • Room Temp / Dew Point / 5 deg C
  • Communications with Bruno _at_ CERN
  • LVDS-TTL Converter
  • Safety Switch feature in acdc.vi

5
Test Procedure
  • 1. Install 4 hybrids 3 min
  • 2. Close cover and purge 4 min ARC Test
  • 3. Seal box when RHlt20 5 min
  • 4. Reduce air flow to 0.2 L/m 1 min
  • 5. Start Cold Cycle 32 min
  • 6. Stable Temperature 5 min ARC Test
  • 7. Start Heat Cycle 4 min
  • 8. Stable Temperature RH 3 min ARC Test
  • TOTAL 57 min

Cooling Rates
  • TEST 2 T50 min
  • 3.0 L/m air, 1.0L/m _at_17 min, 14g/hr 11deg C
    Water
  • TEST3 T32 min
  • 0.2 L/m air, 16g/hr 11 deg C Water\
  • CERN Rate T20 min

8
Future Plans
  • Seal up air leaks in Cold Box
  • Continue write-up of Test Procedures
  • Verify Air Flow sensor calibration
  • New FR1005 Air 0.40 L/minvolt -3

9
Future Plans
  • Calibrate UCSB Hybrid Cold Box after sealing
  • CERN Box is (1820)/25min on cooling
  • CERN Box is (2018)/3min on heating
  • Test 4 Hybrid ARC Stand
  • System move into clean room
