Polhe3 meeting 20110907

• progress
  • new cell and oven bottom piece (zhiwen)
    • The first cell has not been filled due to some complications in the gas system. The second cell is not delivered and won't be until the first one is filled. Alan is working on oven bottom piece.
  • temperature optimization test (all)
    • redid 230 spin down, did 225 spin down (zhiwen)
    • Checked fitting with error estimation, in preparation for notes (Chunhua)
    • water measurement is done, Chunhua is calculating flux (Jie, Chunhua)
  • pulse NMR (all)
    • recorded down the current NMR setup, in preparation for pNMR setup. (Jie)
    • Jie is writing labview program for DAQ (Jie)
  • convection flow study (all)
    • 2 heater is tested. (Jie)
    • installed two new RTD lines. (Jie, Chunhua)
  • transfer tube wall measurement (Jie)
    • did the measurement,refer to Polhe3 cell wall thickness measurement
